12-bolt
My own Moser 12 bolt has survived countless 4000 rpm launches. For those of you who are over 500 rwhp though, I would suggest you go with the Moser 9 inch. The 9 inch is an even stouter rear that can handle a lot of high horsepowered abuse. The only real problem is for those of you who have ABS, you do not have an option but to disconnect the ABS. ABS/TCS owners are in luck, as it is an option on the 9 inch. Bob
