The Steeda Difference: S550 Camber Plates

Our Steeda camber plates (555-8139) have the highest adjustment range on the market. For a 1” lowered car you can adjust your camber from -0.3 degrees to –2.8 degrees. That’s a 2.5 degree adjustment range and higher camber levels are available on cars lowered even further.

Our components are designed from the ground up with function in mind. Our plate thickness is 0.180” and is made of 1008 steel, and is nickel-plated to eliminate the possibility of corrosion.

The design of our camber plates really hit their stride when discussing bearing selection. Our bearings are an extremely high quality ptfe lined (Teflon) bearing. We have a strategic partnership with a US company who provides us with a custom bearing pre-load. This pre-load on the center ball allows us to keep a very low break away torque which minimizes friction in your system. Minimizing friction is important because it affects steering linearity and can also significantly alter the damping of the vehicle. Secondly, this pre-load allows us to make sure there is absolutely no chance of the ball having slop from the manufacturer, or from developing slop over time. This means our camber plates have 100% silent operation, because we hate NVH. We also back that up with a lifetime warranty.

The spherical bearing selected for this unit is rated for over 30,000 lbs statically and over 10,000 lbs dynamically – making it more than capable to handle anything the Mustang, the track or the driver can throw at it. The factory thrust bearing and spring perch are also utilized in our design. Thrust bearings are extremely important for performance applications, yes they are necessary for steering movement in a MacPherson strut but they also reduce spring friction between the spring and the perch when a spring undergoes compression. This is extremely important, spring friction induces secondary undesired spring rates and makes the force which your spring produces unpredictable and inconsistent. Utilizing the factory thrust bearings makes sure we have consistent performance every time. A second benefit of this system is the rubber-coated spring perch from the factory unit – re-using this allows us to keep the spring silent on the perch again for seamless operation. We even go so far as to laser scan the factory units to ensure perfect fitment.

Oh and don’t forget, we rigorously test all of our parts here at Steeda during our product validation phases – between our detailed FEA analysis we have achieved great results. Our Steeda camber plates are rock solid, at forces much larger than the car will ever see the camber plate only deflects 0.002”! Also here are some pictures of us testing the strength of these beautiful TIG welds. With only one weld bead our plates withstood over 40,000 lbs of force!

Steeda – Speed Matters

Steeda’s S550 Mustang Clutch Spring Assist 35 lb/in – Now Available!

Your 2015-2016 Mustang comes with a 185 lb/in clutch assist spring installed from the factory. This high-rate spring is what causes such a vague and disconnected clutch pedal feel (many of you have experienced this). The clutch pedal travels in a circular arc, with the spring assist in the middle of that clutch pedal travel. The middle of that motion compresses the spring initially and then allows it to extend after the first 30 degrees of travel. The combination of a high-rate assist spring and motion of the pedal during engagement causes a non-linear and sometimes confusing pedal feel. Having a non-linear pedal feel makes it hard to modulate the clutch on your Mustang GT, EcoBoost or V6.

steeda-s550-mustang-clutch-spring-assist-35-lb-in-15-16-all-555-7022-01-1

Many new Mustang owners have found that taking out the stock OE spring will give you somewhat similar results, but realistically the clutch becomes far too heavy especially if your Mustang is daily driven. Most owners fail to realize the prolonged effects of simply taking out your factory OE spring and not replacing it with another spring. By negating your factory clutch assist spring you will notice chatter/NVH from your clutch pedal. Your clutch pedal will never fully return to stock position without any assist spring, and over time your slave cylinder may begin leaking due to constant pressure on its seals from the clutch pedal not returning to the stock position. Avoid these problems in the future by installing our Steeda S550 Mustang Clutch Assist Spring 35 lb/in into your GT, EcoBoost or V6.

Our 35 lb/in clutch assist spring completely replaces the factory 185 lb/in assist spring. Our engineers have honed in on just the right amount of spring rate to get you the perfect clutch pedal feel you look for in a Mustang. This assist spring is manufactured from piano wire that naturally has high tensile strength and high elastic qualities. Our piano wire spring ensures a consistent spring rate and minimal sag even after repeated use. With the addition of our clutch assist spring, you will notice a much more linear feeling clutch – the reason being is that we take out much of the influence involved in your clutch pedal motion caused by the assist spring, allowing you to feel exactly what is happening with your clutch engagement.

Key Benefits:

– Improve clutch pedal engagement feel
– Modulate your clutch engagement with ease
– Piano wire construction with high tensile strength and high elastic qualities
– Consistent spring rate and minimal sag even after repeated use
– More linear clutch feel
– Complete replacement of factory 185 lb/in clutch assist spring
– Avoid slave cylinder damage due to removal of stock clutch spring
– Steeda quality, backed by a lifetime warranty

Easily Adjustable
1 full turn = 9/10 degree of camber, nothing needs to be removed to adjust this part. Simply jack up the car, make your adjustment and you’re good to go! Toe will need to be adjusted with it.

Perfect Fitment
Steeda’s development process is always evolving. The factory Ford suspension was laser-scanned and developed into 3d computer models in order to ensure that our parts fit perfectly. No binding or changing of any factory suspension geometry that we didn’t originally intend!

Strength and Stability
An enormous amount of time was spent running through strength simulations of this part. With the large bend needing to clear the chassis, the adjustment sleeve is loaded in a slight bending mode – if not addressed properly this will lead to premature fatigue failure of the system. Our parts are made of heat-treated and nickel-plated 4140 steel for incredible strength and corrosion resistance. Only the highest quality spherical bearings are used, which includes a nylon-coated bearing face to prevent dirt from penetrating into the bearing and ensuring that these rod ends will never need to be replaced. Bend angles, material size and selection, adjustment methods are all engineered to handle the extreme conditions these links are exposed to.

Lowered Deflection
Delrin on one side and spherical bearing on the other rids you of the deflection that the factory bushing allows. This means better camber control in the corner. With the bushing from the factory as you go into the corner, the bushing deflects. This allows the wheel and tire to lean outward, letting the tire lose camber in the corner. This reduces grip and makes the car less predictable as you’re never sure where your camber is at any given time.

With our setup you won’t lose any camber during cornering – you will maintain ideal camber gain throughout the corner. Gain grip, have a more predictable handling experience, and the rear of the vehicle will react to inputs more quickly. This leaves the handling feeling more direct and positive while also making the car much more capable on the track! Steeda also provides these rod ends with specific preloads imparted on the bearing – this ensures the lowest amount of bind on the ball as possible and also ensures that there will never be any slop in your rod end.

Validation
No simulation is ever complete without validation! We have spent over 1 full year testing and developing these parts. These camber arms have spent time in computer simulations, laboratory tests for ultimate and fatigue strength, and have seen thousands of daily driving and track day miles on our Steeda mustangs. We aim to ensure that our final product will provide the absolute best value possible to our customers.

We have these in stock and ready to ship – our Steeda S550 camber arms fit all 2015-2016 Mustangs!

The Steeda Difference: 2015+ S550 Mustang Cold Air Intakes

Modding your car, whether it be a brand new S550 Mustang or something else, can be a very fun and exciting experience – mapping out your upgrade plans, calculating the hp/tq gains, etc. Unfortunately, there’s also a lot of mis-information when it comes to competitors’ products, power gains and overall build quality. In this article we hone in on key differences between Steeda’s S550 cold air intake (CAI) and a competitor’s product. Two main things we’re reviewing in detail are airflow and intake tube design.

Airflow

Building clean, turbulent-free airflow into the intake tube is paramount. Steeda accomplishes this through our industry-leading and technically-advanced velocity stack. The bellmouth in our velocity stack helps air smoothly transition from the filter to the intake tube – this creates the beginning of a healthy laminar boundary layer which transitions to a clean laminar airflow across our mass air sensor.

Steeda S550 CAI Velocity Stack Steeda’s precision CNC mass air housing provides the cleanest mass air signal on the market

Competitor's S550 Cold Air Intake Competitor’s roto-molded mass air housing, note the texture inconsistencies and protrusions which cause turbulence

Most brands do not use a velocity stack and the lip created in their system will ‘trip’ up the airflow, creating turbulent flow from the beginning. Competitors try to remedy this through the use of a ‘MAF straightener,’ which is why there is a screen affixed to the filter in our example below (see image below). However, most MAF straighteners are a honeycomb type of material which allows the air to create a small boundary layer and then re-direct itself. The system in our example looks like it may actually trip up the air more and create more turbulence. Why is this important? The MAF sensor is a temperature frequency-driven sensor – in order to get clean, predictable readings for downstream fuel calculations you need to have your airflow be as smooth as possible. Turbulent air conditions cause erroneous MAF frequency, therefore creating the likelihood of drivability issues.

S550 Cold Air Intake Filter ComparisonCAI filter comparison

Steeda’s CAI utilizes a 101mm mass air opening while one of our competitors utilizes a 110mm mass air opening, although what customers may not realize is that their use of a screen negates their 110mm mass air opening because it causes a restriction. Utilizing a screen is required when the competition’s CAI is not utilizing a velocity stack or bellmouth entry.

Intake Tube

The intake tube itself is extremely important, it must deliver the largest, cleanest amount of high velocity air as possible to the throttle body. Steeda again wins out in total volumetric flow as our intake tube has a much larger and cleaner radius than the others on the market today, which can be seen in our example below. Again, a larger diameter also means more laminar flow is possible at higher velocities than the other brands.

S550 Cold Air Intake Bend Radius ComparisonCompetitor’s inlet tube bend radius vs. Steeda’s

S550 Cold Air Intake Bend Radius Comparison OverlaidCompetitor’s inlet tube bend radius vs. Steeda’s (overlaid)

Other brands may have turbulent flow carried in from the inlet side of their intake tube since they don’t include a velocity stack. Head loss is the amount of pressure loss or velocity loss you get from the beginning of the tube to the end. Bends introduce this type of loss into the system, the more bends you have, the more loss you have and the tighter the radius of those bends the more loss you have. Steeda wins out in this category as we have a larger bend radius on our intake tube and we also have less bends overall when comparing to the other brands.

Also, Steeda’s S550 CAI seals perfectly against the hood, which provides the lowest amount of heat soak possible especially when comparing to other CAI’s on the market.

Steeda’s been designing and manufacturing cold air intakes since the early 1990’s, and we’ll be doing so for many years to come – there’s a reason why Steeda’s kit is the CAI of choice among many S550 owners. We’ll be posting another write-up delving into our CAI comparison and documented hp/tq gains in a controlled environment.

Steeda and Nitto Tire Testing NT555 G2

As many of you may know, Steeda has a long-standing relationship with Nitto Tire – we run their tires on many of our street/strip cars and recently had the exciting opportunity to perform track-testing for their all new Nitto NT555 G2 tires at Palm Beach International Raceway (PBIR).

We brought out two S550 Performance Pack GT’s with equal entry-level mods (Steeda springs, Steeda IRS subframe bushing support system, Steeda cold air intake, Steeda tune) to perform an apples-to-apples test comparing their existing NT555 tire to their all-new NT555 G2 tire.

60-0 Braking:
This kind of testing solely reflects the capabilities of the tires, brakes, and suspension equipped on the vehicle. From a driver-standpoint, it’s imperative to ensure the brakes are hit at the same point on the track at the same speed with max pressure applied to the brake pedal. This technique allows the vehicle’s Anti-Lock Brake system to do its job at peak performance. Considering both vehicles were identical in brakes and suspension, the only variable left was the tires being used. Data we gathered shows the NT555 G2 stopping the car in 76.5’ from 60mph, which is far superior than the current generation NT555 at 96.75’. One thing that these numbers do not show is directional control while applying the brakes – the NT555 G2 had a much more confidence-inspiring feeling transmitted through the steering wheel while the brakes were applied.

orange9

orange10

Driving Experience:
The NT555 never inspired the high-level of confidence that the G2 did while turning into and exiting the corner. What we mean by that is, the G2 – when turning into a corner – transmitted a feeling of the tires gripping sooner than the NT555 by the vehicle actually turning. When the driver feels that the vehicle is now changing in the intended direction that the driver planned, then the driver can place their focus on the exit of the corner maximizing the speed to the next corner; it’s at this point that the driver usually applies throttle to begin the acceleration process. During the acceleration process out of the turn is when forward grip is imperative to achieving a good lap time. The G2 allowed us to not only apply more throttle input, but also had less slip while exiting the corner. When tires slip during exiting a corner, it is usually the rear tires on a rear wheel drive vehicle (such as the S550) resulting in oversteer. When the rear tires slip while coming out of a corner, they are no longer propelling the vehicle forward and instead usually the rear of the vehicle begins to slide in the opposite direction of the turn. If the tires are sliding, usually the driver has to react and either reduce the throttle, or alter the intended direction of the vehicle to compensate – neither of which help to reduce lap times. As we mentioned above, it is also worth noting that braking feel was considerably different between the NT555 vs G2. The G2 seemed to require less pedal pressure to achieve the same desired braking effect as the NT555 – this resulted in less weight transfer while under braking, and a more stabilized feeling while cornering the vehicle as the weight was not all transferred to the nose at turn-in or corner entry.

NT555 Key Benefits:
– compound that offers balance between tread wear and traction
– stable cornering due to reinforced tread blocks
– wide contact patch

NT555 G2 Key Benefits:
– cornering stability due to directional tread pattern
– increased wet traction performance
– increased braking performance
– wide contact patch

2015 Mishimoto Ford Mustang EcoBoost Oil Cooler

When we heard about Mishimoto’s 2015 Ford Mustang EcoBoost Oil Cooler, we had to put it on our Steeda 2015 Competition Orange EcoBoost Mustang!

The entire installation process took about 2 hours – not bad. Especially when you know your turbocharged 4-cylinder engine won’t overheat with this oil cooler as it pumps out over 300 horsepower. This Mishimoto 2015 EcoBoost Oil Cooler is a direct fit, which makes installation a breeze.

Mishimoto offers their oil cooler in either silver or black and they also give you the option to choose between a billet aluminum oil sandwich plate or thermostatic oil sandwich plate. For our installation, we went with the silver oil cooler and the thermostatic oil sandwich plate since we wanted a faster warmup at startup.

All of the parts needed for the installation were included:

  • 3 Application-Specific Mounting Brackets and Spacer
  • 19-Row Oil Cooler
  • 4′ 3.5″ Stainless Steel Braided Hose with 45° and 120° – 10AN Fittings
  • Oil Sandwich Plate
  • 3/4″ x 16 Stainless Steel Sandwich Plate Adapter
  • 2 M20 x -10AN Straight Fittings
  • Mounting Hardware Set

First we lifted our 2015 EcoBoost so we could remove the undertray. After that was completed, we used a flathead screwdriver to remove the eight pop clips that fastened the plastic air diversion cover.

The third stage in this installation process was removing the front bumper. This stage consists of removing the front bumper hardware which are four pop clips, six 8mm screws and two 7mm bolts that are near each headlight behind the fender liner; and unclipping the bumper and six wire harnesses for the turn signals, headlights, and fog lights from the vehicle.

Next we removed the air dam, the air shutter arm and all other connectors that connect to the air shutter motor and the ambient temperature sensor. We also removed the lower grill shutters as well as the arm that attaches the lower shutters to the upper shutters. This gives us the room we need to install the Mishimoto 2015 EcoBoost Oil Cooler.

We then removed our oil filter so that the Mishimoto sandwich plate can attach in place by using the 3/4″ x 16 Stainless Steel adapter.

To avoid any unwanted friction, we lubricated the O-ring on the sandwich plate before fastening it in. Once the sandwich plate and straight fittings are all fastened and secured, we attached the stainless steel braided fittings with the 120 degree fittings connected to the sandwich plate.

We then lubricated the O-ring and reinstalled the oil filter. Next we snaked the oil lines so that they were next to the steering rack. The shorter oil line with the 45 degree fitting was routed into place first since it was the first to be attached to the oil cooler.

We detached the front support bars in order to attach the oil cooler with its application-specific mounting brackets.

After the oil cooler was mounted, we attached the 45 degree fitting and the longer hose with the 90 degree fitting to the oil cooler. We then started reattaching all of the parts we removed during the install!

After our 2 hour installation, we couldn’t wait to test it out on the road and track. The Mishimoto 2015 EcoBoost Oil Cooler reduced our oil temperatures by up to 35+°F. The oil cooler receives the most airflow by being mounted at the front of the vehicle which cools the engine’s oil faster and more efficiently, which is always a good thing with a forced induction setup.
