Default A4 Base Supercharged w/3.73 gears
Currently being installed H/C, LT headers w/Corsa Extremes, E-Force supercharged and RPM Stage 3 rear differential 3.73. Anyone have a similar setup, if so how do you like it? Would you do anything differently?

I have Nitto 555R2s, you think that’ll help?

Theyll help with traction. But as others have said, it'll put an increased load on the trans and diff. The diff will probably be OK, but the trans may not be for too long.

In your opinion, what would be a good trans?

I'm curious on how well that will hook from the dig with 373's, roll racing may be in your future.

are you driving around town or just tracking it? Only reason I am asking is I had a C4 with 4 speed tran, 3.73's and didn't like it. I have lots of interstate near me, which is where I had the issue.

RPM called and strongly recommended that I go with the 3.42 gears instead of the 3.73 so I went with their recommendation.

I would have left the gears alone for now honestly.

I have a converter if you need one? It was a little too much for my setup but I'm spinning a ported Eforce about as fast as you can spin one.
