The Competition Clutch Super Single was developed for cars not quite ready for a twin but needing something more than the conventional Stage 4. The Super Single mirrors a twin disc in the fact that they both are a 7.25" set up and have a 4140 forged steel flywheel. Unlike the twin, the Super Single only uses one disc and tips the scales around 17-20lbs depending on application. 
 
The Super Single is a must have piece for all-motor/nitrous cars running up to 450whp. Currently available for select applications
 
Fits 02-06 Acura RSX, 02-05 Civic Si, 06-11 Civic Si
