Our Sales Experts take calls all the time from enthusiasts that want to eliminate wheel hop in drag racing while also staying on a tight budget. This is where the Stop the Hop Drag Enthusiast Kit comes in. Our team of engineers got together and came up with the best parts for eliminating unwanted wheel hop in the new S550/S650 Mustang to help you get a better time at the drag strip. 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 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 its kind in the performance aftermarket and so innovative and popular we patented its 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. Its job is to prevent up and down movements of the subframe.
The 3rd component of this kit is the strongest support brace for the S550/S650 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 4th piece is Steeda's rear lower control arm spherical bushings which are recommended for all drag race applications. If you drag race your GT, EcoBoost, or V6 Mustang our rear lower control arm spherical bearings will play a huge role in eliminating deflection, ensuring your tires hook immediately upon acceleration. Our spherical bearings stop your Mustang from building negative toe on launch. In addition to eliminating deflection and compliance of the factory bushings, our spherical bearings will also eliminate the spring rate of the factory bushing which does not allow the suspension to articulate up and down freely.
The 5th piece included in this kit is the impressive Steeda Adjustable Rear Camber Arms. These help you dial in that track alignment, correct camber after lowering your Mustang, and help you get a better contact patch at the track. These are CNC machined from 6061 aluminum and offer +2 through -5 degrees of adjustment.
