These kits are for those with a budget in mind when it comes to a T56 swap clutch. These use the factory W58 flywheel (SC300, IS300 and NA supra) or they can be purchased with a billet steel flywheel. The kit price is higher than normal pull-style FX300/FX400 as this kit includes the $550 adjustable hydraulic release bearing! The full face kevlar disc (FX300) is good for 600rwtq, and the 6-puck version (FX400) is good for 700rwtq.
