The T2R - S05 Mod - Twin 225 XT Sprung Race Kit is a game - changer for high - powered AWD vehicles. It combines double ceramic friction surfaces with an ultra - durable Mono - Drive sprung hub assembly in a modular design, enabling aggressive launches and smoother gear shifts. Each diaphragm spring undergoes a special four - stage heat - treating process, giving you a consistent and light pedal feel. The puck - style friction plates made of high - quality ceramic materials offer a high friction coefficient, excellent heat capacity, and a long clutch life. These plates transfer torque evenly to the Mono - Drive sprung hub assembly, which extends the input shaft's lifespan and reduces driveline shock from torsional vibrations. This comprehensive kit includes a CNC - machined and balanced flywheel, pressure plate cover, diaphragm spring, face, puck - style ceramic friction plates, sprung Mono - Drive hub assembly, floater, patented Monoloc Collar, release bearing, alignment tool, and pilot bearing (if needed). Mod - Twin clutches are fully rebuildable, and most components can be ordered separately. This part fits various Subaru WRX STI models from 2004 to 2021, including special editions and different trims.
Using this race kit is straightforward. First, make sure to carefully follow the installation instructions provided with the kit. When installing, use the alignment tool to ensure proper positioning of the clutch components. Once installed, during the initial break - in period, avoid aggressive driving. Gradually increase the load on the clutch as it wears in. Keep an eye on the pedal feel; if it starts to feel different, it could be a sign of an issue. For maintenance, regularly check the clutch components for wear and tear. If you notice any signs of damage or excessive wear, such as reduced clutch performance or strange noises, it's a good idea to replace the relevant parts. Since most components can be ordered separately, you can easily maintain and rebuild the clutch as needed. Remember, this kit is not for street use, so use it only on the track or in appropriate racing environments.
