Do i need a new rear??
Mods are H/C "231/237", headers, and pretty much all the bolt ons. I know it can still blow while shifting gears in a M6 but being that this cam doesn't have a lot of torque down low do you think it will hold with one of these packages, and if so which is the best one for those of you with personal experience. By the way i'm plannig on going with 4.10's.
Thanx in advance
.I put a 4.10in my WS6 last year but I don't race the car
