Our Sales Experts take calls all the time from enthusiasts that want to eliminate wheel hop in drag racing. This is
where the Stop the Hop Drag Ultimate Kit comes in. Our team of engineers got together and came up with the best
parts for eliminating unwanted wheel hop in the new S650 Mustang to help you get the best time possible 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 S650 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 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 Dark Horse 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 S650 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.
Steeda's Rear Toe Links are the 6th item in the kit. They help you improve your launch and allows you to control the
toe of your Mustang during launches. Improve your 60-foot times and get down track faster with this upgrade from
Steeda.
7th in the kit, the Steeda Billet Vertical Links with Delrin Bushings prevents deflection and stiffens the rear of
your S650. This CNC machined 6061 billet aluminum piece is a great step up over the stamped factory piece. Reducing
bushing deflection will help you put more power to the ground, while also preventing unwanted movement and wheel
hop. Bushing deflection from the stock rubber bushings can cost your Mustang energy at launch and will hold your
Ford back from reaching its full potential.
The 8th and final piece of this kit is the Ford Performance Knuckle to Toe Link Assembly. This replaces the factory
rubber bushing and, like above, reduces deflection. This part will improve the handling and help your Mustang
perform at its best.
