FX400: Built for Significant Power Upgrades

Clutch Masters' FX400 uses a ceramic puck disc built specifically for cars with significant power upgrades, going a clear step beyond the FX100 through FX350 in both aggressiveness and torque capacity. This is the 8-puck version specifically, and the puck count genuinely changes how the clutch behaves. The 8-puck design maximizes surface area and holding power, though it can be more challenging to get moving smoothly from a stop compared to the 6-puck version. That's the kind of detail that separates genuine engineering from a basic replacement part.

Hard, Quick Engagement for Serious Driving

Engagement with the FX400 is hard and quick, designed for aggressive drivers and serious road-racing applications rather than a mild daily commute. The ceramic disc provides rapid heat dissipation for repeated hard use, exactly the kind of abuse a street car with serious power upgrades or regular track time puts on a clutch. It's a genuinely extreme-duty option for a driver who's outgrown the FX300 or FX350. It's a small distinction that makes a real difference once you're actually driving on it.
