The FDF Pro Kit, was designed with the demands of professional drifting in mind. This kit delivers unrivalled steering angles and precision control, thanks to its innovative rack relocation. The Pro Kit's debut on Josiah's C6 Corvette led to a spectacular victory, winning both the first competitive event and the high-roller series championship on its first outing.

A normal coilover will contact the upper control arm where the spring passes through the arm. This kit has been tested with both BC Racing and Feal coilovers, these 2 coilovers work when installed inverted (with the spring at the bottom of the coilover instead of the top). The upper control arm is designed this way to maximize steering angle, and it is necessary.

The OEM steering shaft firewall boot must be removed, and the firewall needs a slight notch in it. The reason is the BMW steering rack is narrower, and the steering shaft angle increases towards the center of the car.

The BMW steering rack also requires the factory steering rack giubo. We have machined an adapter to connect to the E46 giubo. The giubo comes with a rubber dampener installed. This can be run as is, or the rubber damper can be drilled out, and the 2 halves of the giubo bolted together.

Key Features:

Adjustability: Our innovative lower control arm/lollipop design introduces on-car fine-tuning for caster, a unique feature not found in other kits.
Angle: Up to 72 degrees of lead and trail wheel angle, made possible only by our rack relocation design.
Self-Steering Dynamics: Tailored for lightning-fast transitions and effortless control, this kit endows your Corvette with the quickest self-steer capabilities Josiah has ever experienced, especially when combined with the rear grip kit.
Grip: The speed of a drift is determined by how well the front can guide the rear; to do this, you need grip. This is a combination of perfecting the camber gain, the KPI, caster and contact patch of the tire while at high angle. It has been perfected to allow for a speed advantage without understeering and showed this well during trials and competition.
Ackermann: Adjustable Ackermann; Josiah’s setup with zero Ackermann and a slight static toe exemplifies perfect control and steering response.
Bump Steer: The Pro Kit has been optimized at angle to have minimal bump steer and maintain control no matter the terrain. The kit comes with specially machined spacers that go on the steering rack to extend the rack's ram. This part is included with the kit.
Suspension Travel: The kit supports 2 inches more travel than the stock suspension design, demanding a minimum spring rate of 18k with sway bars or 22k without, due to the modified motion ratio.
Steering Rack Conversion: The Steering rack has been changed to now use an E46 steering rack. On Josiah's car, he uses the silver/grey tag rack. The racks location uses a unique bracket that fixates it into the factory leaf spring pocket of the subframe. Mounting it here has relocated the steering rack 4.75” back and 5.5” down. A dramatic move but a very necessary one, as the factory C6 racks are in front of the engine's crank pulley. The factory rack is compromised at high angle and will often result in wrecking the rack's seals within a year of competitive driving. This kit resolves this problem by aligning the forces and keeping them linear with the steering rack. The steering rack relocation comes with a rack adaptor to connect it to the factory steering column. The only modification required is that the left side header will need to be custom-made or modified to clear the new steering wheel shaft location. Keep this in mind when considering this angle kit. The subframe will also need a couple of spots ground for the E46 power steering lines and rack fitment (these are minor modifications).
Joints: Uses Chromoly Heim joints and spherical bearings with self-lubricating nylon races.
Durable, Lightweight & Reliable: Made from high-strength alloy steel and aluminum.

Note: Installation requires minor modifications to the subframe and potentially to the left side header to accommodate the new steering wheel shaft location.

Note: Wheel Bearing not included, calipers and pads not included.

Note: Orders require 3-4 weeks for fabrication before shipping.
