Clutch Masters FX400 Clutch Kit Information:
- Designed for track use, but could possibly still be used on the street. Can handle very high abuse and dedicated race events.
- 170% increased holding capacity.
- Designed for maximum holding capacity and not clutch life (might not last as long as an OEM clutch).
- Power Plus 1 pressure plate with an extremely durable ceramic disc. Ceramic disc rapidly dissipates heat and has very quick engagement. Disc may chatter slightly in first and reverse gears.
- Increased pedal pressure. Might not be easy to drive on the street for some.
- We sell the 6 pad rigid, 6 pad spring, full face rigid, and full face spring disc versions of this clutch. The 6 pad option provides the best overall performance and quickest engagement. The 6 pad spring disc version will offer less harsh (but slower) engagements out of the two 6 pad options. The full face disc allows for easier (but slightly slower) engagements compared to the 6 pad, but you can still "slam" the clutch and get pretty fast/harsh engagements due to it not using springs. The full face spring disc has the smoothest but slowest engagement compared to the other FX400 options.
Clutch Masters FX500 Clutch Kit Information:
- Designed specifically for track use. Engages and disengages instantly for extremely fast gear changes.
- 200% increased holding capacity.

- We sell only the 6 pad disc version of this clutch since this will provide the best possible performance and fastest engagement for racing.

Break-in Notes: Please refer to the manufacturer's specific instructions for proper break in details for your application.
Flywheel Notes: A smooth, flat flywheel surface is essential for proper clutch operation. If upon inspection of your Lexus IS 300's flywheel there are signs of scoring, heat damage or warpage, the flywheel should be resurfaced or replaced to assure good clutch performance. IF YOUR FLYWHEEL SHOWS ANY SIGNS OF CRACKING, REPLACE IT! If you unsure about the condition of your flywheel, we highly recommend purchasing a new one. Typically, flywheel resurfacing costs around $80 to $100, but it can be hard to find a quality shop to do it. It is usually almost as cost effective just to purchase a new flywheel.
