Clutch Masters FX400 (3600lbs) Stage 4 Clutch Kit 4-Puck Subaru STI 2004-2017


Clutch Masters 04-08 Subaru WRX Sti 2.5L Eng. 6-Spd (3600 lbs) FX400 Clutch Kit 4-Puck


Heavy duty pressure plate; sprung, 4- or 6-pucked ceramic disc; quick engagement; tremendous holding power. If your STI has major upgrades and is making loads of power and/or your STI is a dedicated track car, then you should look at the FX400 clutch from Clutch Masters. You will experience harsh engagement that is not suggested for daily driven cars, but is ideal for the for aggressively driven weekend toy and track driven STI. Did we mention that engagement is harsh and pedal feel will be heavy? Clutch Masters offers the FX400 as a 4-puck or a 6-puck kit. The 6-puck kit will dissipate heat better than the 4-puck version, but the 4-puck can handle a little bit more power.
