if your planning on gripping with a 75 shot and the bolt ons you have you will have a lot of torque behind you (over 400ft lbs) you can get away with a spec stage 2 also but if you plan on upgrading you should go with their spec stage 3.. they make awesome clutchs but streetability is limited... also life is shorter... honestly i go back to my previous statement.. get the centerforce dual friction clutch.. it is perfect for street and occasional strip use... it will withstand your 75 shot and then some and it is very driveable you wont be dissapointed
