3.90 help!
I need some advice on 3.90 gears. My car is stock and has a manual trans. I've heard that with 3.90's I will need a new diff? Is this true and how do 3.90's perform?

I just did 3.90's on my 2000 z28 you dont have to get a new diff but i would deff get a girdled cover. As far as how they preform i love em car pull hard in every gear 3rd, 4th are awesome, and it makes 6th useable. They are dead quiet also.
