Pedal Box System Overview
Introducing an integrated pedal box that accommodates both acceleration and brake functions, featuring an extensive selection of 7 adjustable settings.
This design ensures a full range of motion for both the brake and accelerator pedals, enhancing the overall driving experience. Designed for fast and secure adjustments to accommodate various driver configurations in under 1 minute, the system is fastened using precision steel clevis pins and steel hairpin cotter pins, ensuring both reliability and ease of use.

U-Channel & Rail Design
Designed to accommodate various drivers, U-Channel is fastened to the rails with precision steel clevis pins and steel hairpin cotter pins, allowing easy and reliable adjustments in under 1 minute.
Twin parallel 1/8’’ steel rails: machined via waterjet with precision 0.2500 holes, and welded to chassis
Aluminium U-Channel: purchased to size and minimally post-machined to accommodate mounting holes and wiring spacing
Heel rest: mounted from the underside of the U-Channel via an intermediate plate to sit on the rails for security
