For the type of racing I am going to be doing I need a clutch that is setup to run WOT for 80 to 90% of the race. Plus I still use it as a recreational vehicle too. I'm not out to make any money racing, I'm just having some fun with it. 40 Degree with Engine Braking makes sense to me, the belt will ride higher I believe. I could totally be wrong but it sounds good in theory. I ask QSC to set it up with my spec's and they did. I have a dealer account with them and Adam has always been the shit when it comes to dialing these in. I sold a few of these for the Commanders, they kick ass.
