"R" stands for "Race" and this setup is no different. The R Series single disc clutch is rated to 850 rwhp/rwtq and is a clutch that thrives at the track. Previously our 11" Ceramic Race Clutch, these clutches are designed to be driven hard at the track with very little to no street use. We utilize proprietary ceramic based friction material along with our 11" Race pressure plate - this mixed with our billet steel cnc machined flywheels make these units very robust and aggressive - all of these units are balanced to less than 0.100 OZ/IN at no additional charge.
These units are designed specifically for the track though they can be driven on the street very little, these are not intended for daily driven applications unless you are absolutely okay with an aggressive clutch that doesn't have a long lifespan. What do we mean by aggressive? It's going to chatter/shudder during take off and will have an on/off feel to it as well as a very heavy pedal effort - this is made worse by lightened flywheel assemblies. We recommend this clutch for any type of power adder in a racing application as long as you're within the power rating of the clutch - this provides an excellent budget based unit for those looking to hold big power and abuse without breaking the bank.
When installed and broken in properly you should expect it to drive like a race car, there really is no other way of putting this - the only exception to this is if you are using an aftermarket master cylinder as the larger displacement will increase pedal effort and reduce the engagement window.
