The package includes a tool to easily screw and unscrew the elastomer in the coil spring. Note: at the time of assembly, make sure to remove both the black rubber pad (if present) and the two white plastic caps (if they are present) from the original brake. Whether you are braking hard or braking lightly, the original setup will allow for inaccurate modulation. The foot will not easily feel the intensity of the force applied to the pedal. Thanks to our Brake MOD, the brake pedal will become similar to that of a real car: the greater the pressure on the pedal, to obtain more intense braking, the harder it will become. This effect helps you a lot during long racing sessions, when the leg loses much of its sensitivity and in the most difficult braking you are no longer able to dose the pedal well. You will avoid locking the wheels. Allows you to perform accurate trail-braking. It is possible to use the brake pedal in many configurations, combining our elastomers and the preload rings. Specific Elastomer for G923: MEDIUM. The pedal travel is reduced by 25%, the brake will be immediately harder, allowing better management of braking at the end of long straights and trail-braking for entering fast corners. Recommended for Gran Turismo cars, GT2, GT3, GT4 and modern Rally cars. The elastomer is supplied with 2 preload rings: 4mm + 2mm. HARD. The pedal travel is reduced by 35%, the pedal immediately offers strong resistance, and allows you to better manage light and powerful cars, helps muscle memory in endurance races, and facilitates trail braking. Recommended for Formula cars and LeMans Series prototypes (LMP). The elastomer is supplied with 2 preload rings: 3mm + 3mm.
