This kit is designed for the demands of competitive drifting, offering a robust lightweight design, it is the only kit offering toe gain under compression, with the ability to setup it up for zero bump steer as well. All other options will toe out under compression which is not ideal for rear grip and control in drifting or racing. The changes made to the knuckles were simulated and tested to optimize the already great trailing arm suspension for the E36/46 chassis.

Key Features:

Proven Track Record: Field-tested by professional driver Connor O'Sully, who took second overall in his 2024 Formula Drift season. This kit has demonstrated its superiority in competitive settings, contributing significantly to a car that's nearly unbeatable on the track.
Durable & Reliable: Constructed from high-strength alloy steel, our knuckles are lighter and stronger than OEM knuckles. The kit includes dual caliper brackets specifically designed for Wilwood calipers and features an easy-to-adjust control arm system. Equipped with uniball bearings and high-strength heim joints, designed to endure the abuse of racing and maintain performance through collisions and contact.
Advanced Engineering: Developed with CAD simulations and FEA testing to meet rigorous racing standards, this kit improves kinematics and vehicle dynamics, ensuring superior handling and responsiveness, with emphasis on the adjustable toe gain control, roll center correction, anti-squat adjustment, and options for the pick-up holes to change the amount of side bite and forward bit this kit can create.
Adjustability: Features adjustable anti-squat settings (FD-legal is the standard) and precision toe adjustments using shims for symmetrical alignment. This allows for the fastest and most accurate setup adjustments available on the market for this chassis.
Easy Installation: The installation process is streamlined with an included guide and video tutorial. Even the weld-on brackets are simplified with alignment holes for accurate placement.
FD Legal Design: Fully compliant with Formula Drift rules, ensuring that your vehicle meets competition standards without compromising performance.
Maintenance Made Simple: All components are designed for easy replacement, with individual parts available for quick exchanges in the event of damage.
Race-Only Application: Specifically designed for use on the racetrack, focusing every aspect of the kit on maximizing your competitive edge.

Note: Because this kit is designed for competition, it will only work with Wilwood brakes, and it also uses a bolt-on style hub and bearing that is a better design vs the press in OEM bearing.
