If you plan to launch hard on sticky tires or DFRs and boost, look into a 12 bolt or 9". That HP level and an M6 can take out a 10 bolt easy. Going to a 3.73 will only make the rear weaker.

you can break the stock diff with stock power if you hook up..... its all a matter of traction not really power youll have a long life on the stocker with shitty tires but with nittos or sticker it wont last long
id do a 9" if money is an issue bu i think the 12 bolt is the best but a 9" would work fine just requires a little modfication i belive and wont have tcs (from what ive read)

You can keep your tcs with a 9" if you want to. The 9" can be built stronger than a 12 bolt. But it is a little heavier and a little more parasitic. But for the strength I think it's worth it.
