Product Overview

Are you looking to cure your wheel hop but want a bit more than our 'Stop the Hop' Starter Kit, though you don't want to go full blown with the 'Stop the Hop' Ultimate setup? Your wait is over. This is our 'Stop the Hop' Enthusiast Kit, giving you our new Spherical Rear Lower Control Arm Bearing in addition to our 'Stop the Hop' Starter kit, to improve your 60ft times even more.

Which "Stop the Hop" Kit is for you?

Eliminate Wheel Hop without sacrificing ride com fort or breaking the bank. Our Per formance Experts got toge ther and came up with the best four components for eliminating unwanted wheel hop in the S650 Mustang. A kit that gives you the fundamental foundation for ultimate traction and suspension compliance. 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 per formance 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. Third to this kit is the strongest support brace for the S650 IRS on the market! Made in house from chromoly 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. Fourth are our Rear Lower Control Arm Spherical Bearings. These eliminate the factory deflection that can cause up to 2 degrees of inward toe upon acceleration, and improve chassis responsiveness. If you drag race your GT, EcoBoost or Dark Horse Mustang, our spherical bearings for the rear lower control arm will assist tires hooking immediately upon acceleration. These four parts were the first of their kind for the S650 Mustang and nothing will prevent unwanted subframe movement or wheel hop better than this kit for the price.

Add the Steeda Adjustable Differential Bushing Insert Urethane System (GTorEcoBoost) to fur ther improve rear end control under launches by minimizing pinion angle changes, reducing differential deflection, and increasing traction.

NOTE:Steeda IRS Subframe Support Braces Will Not Fit Convertible. Kit is not compatible with 2015-2023 Mustang's.
