Details: Design background of the Brake Pedal Spring Kit: Many Logitech racing owners report that the original brake pedal is too soft or too hard, so it can not experience the real brake feel. The modified solution is to improve the feel of the brakes by replacing our specially designed brake springs and simulated vacuum hydraulics. This is by far the cheapest way to convert. Advantage: Transform your brake pedal with a progressive rate to simulate the real feel of a brake pedal in a real car. Improve pedal feel with a proportional increase in firmness. Simulates a real brake pedal. Suitable for:  For Logitech G27 G29 G920 Racing Wheel ( If you are not sure if your model can be installed, you can contact us to confirm.) Packing includes: 1 * Specially Designed Brake Spring 1 * Screw For Sealing 1 * Rubber Ring For Sealing 2 * Wrenches
