Steeda Mustang 'Stop the Hop' Street Starter Kit (2015-2026)

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/S650 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 Mustang 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 square up the rear subframe to the chassis, limiting side-to-side and front-to-back movement of the subframe under hard acceleration and braking. Second is our tried and true IRS Subframe Bushing Support System, an 8-piece kit made in-house from billet 6061 aluminum with stainless steel hardware that fills all the factory voids in the IRS subframe mounting locations to prevent up-and-down movement of the subframe. The third and final piece is the strongest support brace for the S550/S650 IRS on the market, made in-house from chrome moly steel and designed to support the factory subframe by directly tying it into the chassis at key mounting locations with a 5-point, bolt-in design.

Note: Steeda IRS Subframe Support Braces will not fit convertible models.
