I believe this will give me enough reason to do the rear-end gear swap finally! "Hey, while your back there, here's a 3:90 gear..."

I've got a 4.10 rear end sitting in the garage waiting for a clutch to go with it. I bought it used and it doesnt look like it was leaking before.

Think I should throw these new seals on it just in case?

What does everyone think of the 4:10? I've talked to many people around Atlanta and overall, the 3:90 seems to give great results.

I had 4.10 in my 94 TA M6 and liked them a lot. It made 6th gear more usable. In my C5 they will be slightly less agressive since I'm using a 1" taller tire than I had in that car.
