Reducing the Brake Force (BRF) value in the Tuning Menu means you reach 100% brake input with less pedal effort. We do not recommend replacing the elastomer springs with a softer material. The CSL Pedals Load Cell Kit is designed to offer heavy resistance, similar to that of a real race car pedal. A higher resistance is not only more realistic, but it is also more effective when training muscle memory for accurate threshold and trail braking. To get the most performance from this product, it is important to hard-mount your pedals to a rig or wheel stand, and use a secure seat, so that you have the confidence to repeatedly apply large forces on the brake pedal.
