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!

Steeda’s S550 Tri-Ax Race Short Throw Shifter is Here!

Thought we just focused on suspension? Drivetrain is our forte as well!

Steeda’s S550 MT-82 Tri-Ax Race Short Throw Shifter is a full factory shifter assembly replacement for your 2015-2016 Mustang GT or EcoBoost. Our race short throw shifter eliminates all slop and deflection of the factory shifter, and still retains the factory shift knob, pull-up style reverse lockout and backup camera functionality.

Product Benefits

- 30% throw reduction
- 20% lighter than the competition
- Eliminates slop and shifter deflection
- Shift knob sits 1″ lower for ideal ‘power shifting’ position
- Top-loaded installation with adjustable springs, in-car assembly
- Retains factory pull-up reverse lockout, OE thread pitch, and back-up camera functionality
- Includes Steeda’s shifter base bushing bracket
- Precision-fit bushings for a direct positive feeling shift

- Made in the USA

Steeda S550 Tri-Ax Race Short Throw Shifter – GT | 555-3717
Steeda S550 Tri-Ax Race Short Throw Shifter – EcoBoost | 555-3718

With the replacement of your factory shifter assembly with our short throw shifter, you will notice a 30% reduction in throw between gears. Our shifter assembly will also lower the shift knob by 1″, putting it in a better ‘power’ shifting position. Our Steeda S550 Mustang Tri-Ax Race Short Throw Shifter is quieter than the stock shifter during daily driving, although during race applications you may notice a slight NVH increase.

One of the great benefits to this shifter assembly is that it’s completely top-loaded. Our short throw shifter for your 2015-2016 Mustang GT or EcoBoost comes with 2 different spring set options for a fully adjustable shifting experience. The kit comes complete with 2 medium-resistance springs and 2 high-resistance springs. The Steeda Tri-Ax has adjustable return springs to fit every drivers’ preference on shifter feel. Using an offset spring tension ensures that you hit your 2nd-3rd gear change every time. Since our S550 MT-82 short shifter is top-loaded, once the base plate is mounted, you can change all of your springs, levers and other options all from inside the car without taking out the full shifter assembly!

Our Tri-Ax shifter features rigid mounting in the front and Steeda poly bushing in the rear, virtually eliminating slop and shifter deflection. With less deflection you will feel a much more direct gear change. The assembly is transmission and chassis-mounted so you don’t get the ‘walking’ affect of a fully transmission-mounted assembly, all while still gaining a more rigid shifter feel. Factory shift shaft bushings are replaced with wider, high-quality machine-finished, low-friction bushings. Tolerances are controlled up to a half thousandth of an inch to ensure OE-quality fitment, alignment and shaft actuation. These features alone make our Steeda Tri-Ax one of the most positive feeling shifters on the market today. To top it all off, our Steeda Mustang GT shifter assembly includes Dynamat sound-deadening material to close out your transmission tunnel and ensures your S550 stays as quiet as the stock assembly.

Steeda’s S550 Mustang MT-82 Tri-Ax Race Short Throw Shifter is manufactured from high-quality aircraft-grade aluminum making it 20% lighter than the competitions’ shifter assemblies. The shift lever itself on our Tri-Ax is made from heat-treated and nickel-plated 4140 steel, making it the strongest part out on the market. All hardware is stainless steel for the highest corrosion-resistance possible. Included in our kit is hardware to tighten up the factory shift knob perfectly into a locking position. These parts have been put to the test on the street and the track and are proven not to bind under extreme conditions or temperatures.

Priced competitively at $439.95 and backed by a lifetime warranty, pick-up one of our Tri-Ax shifters today and shift with confidence!

Steeda’s Vortech S550 Goes 11.2 on Street Tires in Road Race Trim

The team at Steeda was curious how our Vortech supercharged S550 pushing 671 rwhp would do at South Georgia Motorsports Park (SGMP) down the 1320 – while on street tires and still outfitted with our road racing suspension setup (sway bars on full stiffness). After being flogged by Evan Smith, former editor of Muscle Mustangs and Fast Fords, we took our S550 to the strip to see what she could do.

FullSizeRender

Even in 80% humidity this past weekend at SGMP, our Triple Yellow 2015 Mustang GT didn’t disappoint. We ran an 11.25 @ 126.78 mph on 20″ Nitto street tires, and there’s definitely a lot more we can get out of the car with a bit of fine-tuning; this is a daily drivable 671 rwhp monster that’s capable of high 10′s all while on the stock fuel pump and full luxuries of the interior.

Stay tuned for updates as we aim for the 10′s with our 2015 GT!

Steeda’s New S550 Axle-Back Exhaust

Steeda is proud to introduce our new S550 Mustang GT Axle-Back Exhaust System! We’ve designed this fastback exhaust system to bring out the deep muscle car tone that’s begging to come out of your 5.0L powerhouse. Our exclusive axle-back exhaust design improves exhaust flow and is the perfect combination of sound and tone without introducing any unwanted drone.

Our axle-backs are constructed from 409-stainless steel, known for being corrosion-resistant. The tips of our Steeda axle-backs are made of polished 304-stainless steel and feature a laser-etched Steeda logo. The piping size is 3″ all the way up to the chambered mufflers – the tip size steps up to a nice big 4″ that fills in the factory rear valance perfectly.

Similar to other S550 axle-back exhausts, installation will require some fabrication – in order to install this axle-back kit, you will need to cut and remove the factory assembly. Once removed, our Steeda S550 axle-back system can be clamped on.

We designed this kit to be ideal for the daily driver who’s looking for a deep, muscle car tone when they want it while providing zero drone whatsoever.

Key Benefits:
- Adds aggressive muscle car tone
- Great for daily driving, zero drone
- Constructed from 3″ 409-stainless steel piping up to the mufflers
- Featuring 4″ 304-polished stainless steel tips
- Made in the USA

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.

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.

Steeda – Speed Matters

Evan Smith Track Tests Steeda’s 686 rwhp 2015 Mustang GT

Evan Smith said it himself, “This Mustang eats up the track and leaves you plenty of performance for the street.”

The team at Steeda Autosports has been hard at work developing new parts for the S550 platform and we’ve turned our Triple Yellow Q650 2015 Mustang GT into a corner-carving track monster. Pumping out 686 rwhp on 10 psi and pump gas, it’s a force to be reckoned with both on and off the track.

“Our objective with the Q650 and our Q-series of Mustangs is to build a track-ready car that outperforms much more expensive cars for far less money,” said Dario Orlando. “We manufacture and sell our own parts so you can purchase a complete car with the Steeda package installed, or add the parts to your existing Mustang. For the 2015, we first built a mockup of the front and rear suspensions. This allowed us to analyze the suspension arrangement and note the areas of concern as they relate to high performance. We’re looking to satisfy the performance-minded enthusiasts who wants a fast, capable street car that is ready for the track.”
