Gears & Axles - Gearing and rear end

Hey guys I have a 2000 Trans am ws6 6 speed with full frame rails and minor add ons. My posi is no longer locking all the time and I am looking to switch the ten bolt with a twelve bolt with 4.10s. After doing this I want to throw a 100 shot wet kit and probably a super charger. Good or bad idea? Or what should I go with for gears and rear end without wrecking my 1/4 and street fun?? Thanks

Probably 4.10 gears, especially if your gonna be spraying it or supercharging. Turbocharging I'd probably leave the 3.42 in it.

You question should be: Is a 12 bolt a good rear end choice for a sprayed M6 car?
