Feature: 1. Realistic Pedal Feel: The brake pedal upgrade spring changes the brake pedal rate progressively to simulate the real feel of a brake pedal in an actual car. 2. Improved Sensation: With a proportional increase in hardness, the upgraded spring enhances the pedal feel, simulating a real brake pedal, and improving the consistency of each lap compared to unmodified pedals. 3. Maintenance Free: This upgrade spring ensures safety and requires no maintenance. It works without the need to hard install the pedal and remains comfortable even when used barefoot. 4. 3 Level Design: Features a 3 level spring design, which increases resistance with added pressure, pushing it up to +80%, providing a reliable spring for extended use. 5. Consistent Spring Stiffness: The stiffness of the spring corresponds with the brake threshold in game, eliminating the need for software adjustments or recalibration.
