Rear end gears
I have a 2008 vette. With an Edelbrock supercharger, 554 H.P. Automatic LS-3 C-6 with stock rear gears. (223) I think. I would like to go to 315. I would like to know the advantages and disvantages of this move. I tried Richmond gears, as well as a few others and found out they only offer, 342, 373, 390 and 410 Ring & pinion I would like a complete sealed unit. DO you have to drop the trans for this install? THanks.

With the E-Force supercharger and it's greatly increased low end torque, I would be leery of going with the 3.15's. You might just blow the tires off everytime you get on it in first or second gear.

I wouldn't recommend it.

But I do believe that the A4's 3.15 gears (ring & pinion) themselves might fit inside your current carrier, but don't quote me.

You can't exactly do much launching on the street with street tires, and from a roll the benefits of a torque converter are much less (although benefits still exist).

I have an 07 with eforce and 3.42 gears. Its definitely a blast on the street but has serious traction problems. I will be looking into tires soon to try and improve that.

Here is a table that I got off this Forum a short while ago. It may help your decision. Click on the appropriate box for the ratio your interested in and it will tell you the speeds for 1st thru 6th for all transmission types.
