The team at Steeda was asked to come up with a lightweight Jacking Rail system that didn’t add a bunch of weight to your 2015-2016 S550 Mustang. Well, the wait is over! Made in-house from the same material we have used to keep Fox Mustangs from flexing for 25+ years, these chassis Jacking Rails feature CAD-designed, laser cut, high-strength steel brackets and stout 2″ x 1-1/2″ steel tubing. Powdercoated wrinkle black for a low key, yet durable finish, these will last a lifetime under your S550 Mustang. Unlike the other options available, Steeda includes Zinc-plated, flange-headed, grade 10.9 hardware – a simple bolt-in design that can be removed at any time as they use factory mounting holes. These allow you to jack up your Mustang with confidence anywhere along the jacking rail, preventing damage to your factory pinch welds. They provide a great point for jack stands and 2 post lifts. Lastly, these will work with Steeda’s IRS Subframe Support Braces without interference. Steeda’s new Ultra Lite Chassis Jacking Rails add strength and function to your modern muscle car.

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.
- 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
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).
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.
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
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.

After we removed the air shutter arm.
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.

If you have substantially lowered your vehicle, chances are you have introduced bumpsteer. What is bumpsteer? Bumpsteer relates to changes in toe caused by suspension movement.
Every car has bumpsteer, however when you lower the vehicle you increase the amount of bumpsteer that occurs – if this becomes excessive you will begin to notice some unwanted vehicle driving characteristics.
Excessive bumpsteer is undesirable because it means the suspension is steering the car instead of the driver. If your car is lowered and has tracking issues and less predictable steering behavior, you need a bumpsteer kit!
You shouldn’t have to sacrifice your steering when you lower your vehicle, so at Steeda we’ve designed bumpsteer kits that will allow you to correct your suspension’s geometry and can do so without requiring you to drill or modify your vehicle spindle. In addition, our bumpsteer kit makes a great service replacement for your worn out, high mileage outer tie rods even if you do not have excessive bumpsteer issues.

We’ve been extremely busy with product development over here at Steeda – our main focus has been a turn-key wheel hop/IRS subframe solution for the S550 and we hit the nail on the head with our IRS Subframe Bushing Support System!
Made from CNC machined, 6061 aluminum, our bushing support system gives the rear end a much more solid feel with no increase in NVH at all. The Steeda IRS subframe bushings eliminate rear subframe movement notorious in the 2015 Mustang GT, EcoBoost, and V6. A stiffened subframe allows the car to increase traction to the rear wheels and helps eliminate wheel hop.
Steeda Kit Pros:
- Helps reduce wheel hop by eliminating subframe movement, therefore giving you much better rear suspension compliance
- No permanent modifications are necessary
- Easy, 30 minute installation, can be done on jack stands in the garage
- Our kit doesn’t increase NVH at all
- Can be removed or installed in less than 30 minutes
- Completely eliminates over ½” of travel in the factory IRS subframe
- Doesn’t require a rear end alignment
- Lifetime warranty
- Track-tested at the drag strip and the road course – we are not just straight line people
Competitors’ Kit Cons:
- They make you replace the factory bushings completely with urethane or solid aluminum
- A complete removal of the IRS subframe is required; this not only takes several hours, but it’s not the easiest job for a ‘do it yourselfer’
- Other kits will increase NVH if using solid aluminum bushings or very hard urethane
- Takes hours for installation
- Although other kits may reduce wheel hop, an increase in NVH is not desirable
- You will need to re-align your car if you replace the bushings that locate the rear subframe
- No bushings carry a lifetime warranty, they will fail eventually
We’ve attached some product photos for reference – also, this kit is readily available! Steeda’s IRS Subframe Bushing Support system greatly reduces wheel hop while virtually eliminating all IRS subframe movement. When these pieces are used in conjunction with our other Steeda rear suspension components, wheel hop and subframe movement is eliminated – stay tuned as these additional rear suspension pieces will be available in the next couple of weeks.
Again, this is not a permanent modification! It can be put back to stock in under an hour as it’s very easy to install.
Before and After comparison:
Why IRS subframe movement must be eliminated…
As you can see in the video, when completely stock, the entire rear IRS subframe assembly moves around under acceleration, braking and even more so when bangin’ gears. This is a major problem because every single rear suspension piece is connected to this subframe. So as it’s moving and vibrating, so is the rear sway bar, toe links, integral links, camber arm and lower control arm. They are all moving around violently as well so it makes it very hard for your suspension to ‘work’ and keep the tires planted on the pavement for traction. The assembly is basically fighting the car and not allowing for the suspension to work the way it was designed. This causes unwanted changes in camber and toe which will lead to unpredictable traction and control, resulting in handling issues. Steeda’s simple kit eliminates this. PERIOD.
Steeda’s MT-82 Transmission Mount Bushing Insert is a must for any weekend road racer. Our Transmission Mount Bushing helps reduce transmission movement, assisting in keeping the shifter aligned with the transmission, all while reducing any chance of missed shifts. Also, it is easily able to be removed and reinstalled on track days!
This upgrade is an easy install and provides huge benefits! Just watch our video for a step by step installation:
Don’t just take our word for it, here are a few customer reviews:
“Bought this on an impulse and am definitely glad that I did. Wasn’t really experiencing inconsistent shifting very often, but I can definitely tell an improvement in shifting post-install.”
“Install was straightforward (even moreso thanks to the video) and shifting has definitely improved. Shifts feel more direct! Shipping was fast too, thanks Steeda.”
So if you want to reduce any chance of missed shifts and take advantage of an overall better alignment between your shifter and transmission, then don’t hesitate to upgrade!
As always, our Steeda sales team is here to answer any questions you may have!
