gears??
I'm about to put 3:90s in my 01 C5. I have an A4 and run 28X10 Hoosiers @ the track. I'm hoping it'll be a good improvement over my 3:15 gears that are in the car now. I run N20, and shift @ 7200.

be careful! I just had a brand new RPM 3.73 diff put in my car. In less than 400 miles, it died! RPM says they got a bad batch of ring and pinion gears from their supplier. Ask your supplier about this! I am going to have to have mine pulled out, and replaced with a 3.42, becasue RPM says they are recalling ALL 3.73s!

Yes, the shop that installed them did two heat cycles per RPMs reccomendation. After that, I was told to take it easy for 500 miles. I never got over 3000 RPM, and never pushed it.
