With the 400 lbs ft of torque, it’s pretty easy to spin the wheels in a 2017 Mustang GT. And if you get on it from a dead stop, you’ll likely get wheel hop. Steeda looked into this and came up with a kit of parts to add to the IRS in the rear to tighten it up. Great Christmas present to myself.
Steeda S550 Mustang ‘Stop the Hop’ Starter Kit
Our Sales Experts take calls all the time from enthusiasts that want to eliminate wheel hop while also staying on a tight budget. This is where the Stop the Hop Starter Kit comes in. Our team of engineers got together and came up with the best 3 parts for eliminating unwanted wheel hop in the new S550 Mustang. A kit that gives you the fundamental foundation for ultimate traction and suspension compliance. As we have explained before, the factory IRS subframe, (often inaccurately referred to as a cradle), mounts to the S550 chassis with 4 mounting locations utilizing 4 soft rubber bushings with plenty of voids, even in the bolt holes. The kit we put together addresses these issues and more.
First is our Alignment dowel kit. This fills the factory bolt hole voids with CNC machined delrin inserts that will square up the rear subframe to the chassis. By filling these voids we are also limiting the side to side and front to back movement of the subframe that is present under hard acceleration and braking.
Second is our tried and true IRS Subframe Bushing Support System. This 8 piece kit was a first of it’s kind in the performance aftermarket and so innovative and popular we patented it’s design! Made in house from billet 6061 aluminum and featuring stainless steel hardware, this kit fills all the factory voids in the IRS subframe mounting locations. It’s job is to prevent up and down movements of the subframe.
The 3rd and final piece to this kit is the strongest support brace for the S550 IRS on the market!! Made in house from chrome moly steel, this brace is designed to support the factory subframe by directly tying it into the chassis at key mounting locations. Using factory mounting locations on the factory frame, this 5 point brace supports the front factory mount and the lower control arm mount as well. A simple bolt in design this brace ties the subframe to the chassis in the best possible way.
The best part about this kit, is the price. These 3 parts were the first of their kind for the S550 Mustang and nothing will prevent unwanted subframe movement or wheel hop better than this kit.
NOTE: Steeda IRS Subframe support braces will not fit convertible
Billet Aluminum Vertical Links
The Steeda tech I talked to suggested I add Billet Aluminum Vertical Links with Polyurethane Bushings to the intro kit.
Featuring our all new polyurethane bushings, Steeda’s S550 Mustang Billet Aluminum Vertical Links provide less deflection than the rubber bushings in the stock vertical links, but do not add any NVH.
Made from 6061 aircraft grade aluminum, these links will keep your S550 wheel alignment dialed-in and help keep the power planted to the ground. The larger polyurethane bushings, combined with billet steel sleeves and spacers, offer more control through jounce and rebound while still offering plenty of compliance, causing absolutely no suspension bind or an artificial spring rate.
Our one-piece billet design is accurate down to one-thousandth of an inch (0.001″). The S550 Mustang geometry requires a precise length Vertical Link (something not possible with a welded design), as a either a longer or shorter piece will drastically degrade handling and stability.
These Vertical Links are an excellent component for road racers, giving better stability under severe and high speed hard braking.
Made in the USA and backed by a lifetime warranty, give your S550 Mustang the best parts possible go with Steeda, where Speed Matters
