FX400 Clutch Kit: 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.

FX500 Race Clutch Kit: FX500 clutch kits offer a holding capacity of 200-400%
over stock and utilize a solid hub for fast engagement. This clutch is
not recommended for STIs that see any street driving. It is a unsprung
style disc that will yield an extremely hard and quick clutch engagement
with no slippage. This is the perfect clutch for full race or drag
modified STIs that have upgraded gear sets only. This kit would be
nearly impossible to drive on the street, so please be sure you do not
purchase this kit with daily driving intentions. The 6-puck kit will
dissipate heat better than the 4-puck version, but the 4-puck can handle
a little bit more power.
