Kit Components & Features
IRS Subframe Alignment Dowel Kit
Machined Delrin inserts fill factory bolt hole voids to square the subframe to the chassis and limit unwanted movement during launches and braking.
IRS Subframe Bushing Support System
An 8-piece patented design made from billet 6061 aluminum, filling factory voids to eliminate up-and-down subframe movement. Built for durability and precision.
Chrome-Moly IRS Subframe Support Brace
The strongest S650 IRS brace available. This 5-point support system ties the subframe directly to the chassis using factory mounting points for unmatched rigidity and launch consistency.
Rear Lower Control Arm Spherical Bearings
Essential for drag racing, these bearings remove bushing deflection and prevent negative toe buildup on launch, helping your tires hook immediately for faster 60-foot times.
Adjustable Rear Camber Arms
Crafted from CNC machined 6061 aluminum, these arms provide +2° to -5° of camber adjustment, perfect for dialing in a race alignment and maximizing your contact patch.
Adjustable Rear Toe Links
Maintain complete control of your toe settings under hard acceleration, helping you improve launches and reduce quarter-mile times.
Billet Vertical Links with Delrin Bushings
Upgraded CNC machined billet aluminum links reduce deflection and stiffen the rear suspension. More power to the ground with less wasted energy.
