Clutch Masters 02-06 Acura RSX 2.0L 5spd / 02-10 Honda Civic SI 2.0L 6spd FX700 Race Twin Clutch Kit
Turbo and supercharged K20 builds in the RSX and Civic Si quickly outgrow any single-disc clutch that still drives well. Clutch Masters 08037-TD7R-S is the race twin disc for the 2002-2006 Acura RSX and the 2002-2011 Civic Si, sold with a billet steel flywheel, and it is aimed squarely at drag and track cars that launch hard and shift at high rpm.
Our catalog title uses the older FX700 name; Clutch Masters lists 08037-TD7R-S in its current 725 Series Race line. The clutch uses two 7.25 inch (184 mm) friction discs separated by a floater, so it fits easily inside the K-series bellhousing while offering about twice the friction surface of one disc of the same size. TD7R means both discs are rigid ceramic, the most aggressive stage in the line, chosen for holding launches rather than for smooth pickup.
Clamp load comes from a billet aluminum cover, Type 3 hard anodized, that Clutch Masters says flexes about 0.003 in, against up to 0.030 in for a cast or stamped cover. The QR quick release pressure plate uses three spring-loaded bolts for even release and less internal chatter. The S suffix kit ships with a steel flywheel machined from 1045 billet and black oxide finished, which holds heat better than aluminum on repeated launches. Clutch Masters lists the kit at 25 lb and sells the release bearing separately as a replacement part, so check what your box contains.
Check the clutch hydraulics first: these cars have a small master and slave, and air in the line can make a good clutch feel like a bad one. Then do a fourth gear pull and compare rpm with road speed. The shift flare vs slip guide explains how to tell clutch slip from an engine or tune issue, and the twin disc vs single disc comparison covers whether a race twin suits your driving.
Our listing covers the 2002-2006 Acura RSX 2.0 liter and the Civic Si 2.0 liter. Clutch Masters' application list for 08037-TD7R-S is broader: RSX base five-speed and Type-S six-speed 2002-2006, Civic Si 2002-2005 five-speed hatch, Civic Si 2006-2011 2.0L six-speed, Civic Si 2012-2015 2.4L six-speed, TSX 2004-2014, Accord 2003-2012 2.4L, ILX 2013-2015 2.4L and the Canadian CSX Type-S. Note that the 2002-2005 Civic Si is a five-speed car, not a six-speed. K24 swaps and mixed engine and gearbox combinations should be confirmed with us using the year, VIN and transmission code before ordering. More Honda and Acura clutch kits are in the rebuild kits department.
When the discs eventually wear, the Clutch Masters rebuild kit for 08037-TD7R refreshes the clutch pack without buying a whole new kit, and worn engine and transmission mounts will amplify race-clutch harshness, so check them while the car is apart.

The S version comes with a billet 1045 steel flywheel. Steel handles heat from repeated launches better than aluminum and adds some rotating mass for easier pull-away.
Clutch Masters sells a replacement release bearing separately for this kit, so plan on buying one if your box does not include it. Always fit a new bearing with a new clutch.
Clutch Masters says the FX725 is focused on drag racing and is not ideal for the street. TD7R uses two rigid ceramic discs, so expect sharp engagement and chatter. The TD7S Street and Race version is friendlier for occasional street use.
Yes. We carry the Clutch Masters rebuild kit made for 08037-TD7R, which replaces the friction pack.
