Our team of engineers got together and came up with the best parts for eliminating unwanted wheel hop in the new S550 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.

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 S550 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eSteeda's Rear Toe Links are the 6th item in the kit.

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.\u003c\/p\u003e\n\u003cp\u003eThe 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.

If you lowered your daily driven S550 Mustang, running the correct camber will eliminate uneven tire wear. Our camber plates are ideal for both daily driving or tracking your S550. With the addition of these camber plates you will be able to dial in precise front suspension camber for each front toe adjustments resulting in a more balanced and predictable vehicle on the street or track. You will notice improved overall handling capabilities, elimination of understeer and increase in your Mustang's turn-in response.
