Give your 2015-2019 Mustang the proven performance of Steeda manufactured suspension parts. This Steeda Stage 2 Handling Package for your 2015-2019 Mustang GT/EcoBoost is designed to stiffen the front chassis, stiffen the front subframe, and increase traction.

Steeda Stage 2 Handling Package for your 2015-2019 Mustang GT/EcoBoost begins to stiffen the chassis of your S550. A stiffer more confident chassis starts with our Steeda Strut Tower Brace. Our Steeda G-Trac Brace helps stiffen connecting points between control arm mounts and the rear subframe making your load path more direct.

Along with chassis stiffening, our Steeda Stage 2 Handling Package begins to address wheel hop issues notorious with the new 2015-2019 Mustang. The Steeda IRS Subframe Bushing Support System helps with rear subframe deflection that is a direct cause of wheel hop. This bushings stiffen the rear subframe allowing the car to increase traction to the rear wheels. In conjunction with the bushing we give your our IRS Subframe Alignment Kit, which insures your subframe is directly aligned to your chassis, and insures straight launches off the line.

Customer Reviews

Launch the car and you can notice a difference in deflection
Steeda IRS bushing inserts: Install is very easy and you don't notice any difference in ride comfort or noise. However, while I did these the same time as Eibach Sportlines, they stand out on their own. Launch the car and you can notice a difference in deflection. IRS subframe connectors: Obviously no noticeable NVH changes, but the car does feel better when you gas it hard out of a corner. I'm looking forward to testing this beefed rear at the track soon.

wheel hop on my car is 100% eliminated
A couple of months ago, I started looking into overhauling the suspension of my 2015 GT PP. Up to that point, I had put about 7000 miles on my Mustang which allowed me to get a good sense of the issues with the IRS and overall suspension in stock form. Specifically, I wanted to stiffen up the entire rear end and eliminate the dreaded wheel hop while keeping NVH as close to the stock levels as possible. I also decided to replace the stock PP springs and sway bars in order to improve the overall handing, reduce body roll/brake dive and get rid of the bouncy ride. After going through a ton of feedback on the various solutions from the aftermarket (a lot of which came from fellow mustang6g members), I decided to go with Steeda. Below are the parts I chose to go with. Differential Bushings (Red/Street) Subframe Alignment Kit Subframe Bushing Support Vertical Links Rear Toe Link Subframe Suport Braces Linear Sport Springs Front and Rear Sway Bars and Billet Sway Bar Mounts Bumpsteer Kit I already had the Extreme G-Trak Brace installed. Now to the most important part...the results. The handling of the car is on a whole different level after the suspension upgrades. Minimal pitch and roll during braking, turns and transitions. Overall, the entire car is very tight with much better turn in. As expected, the biggest improvement is the rear end. The power delivery through the IRS is fantastic. The wheel hop on my car is 100% eliminated. The rear tires feel as if they are glued to the ground. Coming out of corners, I am able to get on the throttle earlier and more aggressively without any drama. In terms of NVH, I hear some gear whine in 6th gear under minimal throttle between 75 and 80mph (windows closed/stereo off) as a result of the differential bushing inserts. Apart from that, I can't tell a difference compared to stock. Even the ride quality feels great. My fiancé couldn't tell that anything had been done to the car. Overall, I am very happy with the results. Props to Steeda for the excellent work they have done. In the near future, I am looking forward to adding a quality set of performance shocks/struts and hitting the road course.

I now have ZERO wheel hop!
I forgot to update this after installing the Steeda springs and wheel hop kit, I've had them on for a couple weeks now. I'm loving the look with the springs, and there is definitely a noticeable difference in handling. Ride quality suffers a little, but it's not terrible. The wheel hop kit (IRS subframe bushing support system) does exactly what it's advertised to do, I now have ZERO wheel hop!

The handling of the car is just perfect
I am beyond please with everything that Jamie did for the installation and alignment. David was an absolute pleasure to deal with in buying and setting up the appointment for me. Everyone at Steeda has been a joy. The car has been completely transformed. The ride quality with the progressive springs is 3 times better vs. the stock GTPP springs. The handling of the car is just perfect. It is so, so flat now when pushing the car hard in any type of turn. Brake dive has been greatly reduced. I would say by 80-90%. I can mash the brake pedal and it just stops, so tried and true. The front-end barely dives at all. This is from 70-75mph and just mashing the pedal. It truly begs for more speed when entering turns. Of course, this only on roads and not a race track or autoX course. Wheel hop has been greatly reduced. I still have a couple more parts to order to virtually eliminate it all together and those will be ordered at a later date. Shifting hard to 2nd gear, I just now get wheel spin and no hop. Only time I get a little hop is via a hard launch. But again, it is greatly reduced and doesn't happen all the time. The car is so quiet, no increase in NVH in anyway. This has been some of the best money I have ever spent on any car mods, PERIOD. Their parts deliver what they promise and produce outstanding results. Anyone on the fence, I highly recommend you go ahead and purchase their "stuff".

I'm officially a believer!
Ok. So I know everyone has already made threads about their Steeda stuff, but I'm officially a believer! Springs Sway bars Sway bar Billet Brackets Vertical Links Toe Arms Bump steer kit G-Track Brace IRS bushings MMR Camber Plates Performance wheel alignment The car is a go kart. Set the front sway bars to the center and rear to the lower settings, entry high speed turn is predictible, so much so I haven't learned the limits yet. The ass can be easily manuvered with throttle (Race mode/traction off). The body roll seems like it's gone (once the track wheels/tires come in I'll know for sure), it's unreal, I am in LOVE with the car now. This is the way it should've come from the factory for the PP cars. Really a learning curve, since now everything is souch more compossed. The IRS bushings and arms drastically changed the feel of the car on take off, the power actually goes to the tires (which I spin even easier now, even with camber still within factory specs.) There's not that feeling like the IRS wasn't properly fastened, it feels like it's built in to the body. Such a great mod. I'm ordering the IRS brackets as well, but I don't see how it can really improve further. It that good!! Steeda has my vote!
