Gearing
I have done some searching with different words and nothing has come up. What are you guys/gals going with on C4 cars with M6 trans? I was thinking 4.11's?? I heard 3.07 is the performance gears these cars come with. Sounds pretty week. What the heck do the C4's come with as a standard gear set, 2.73's??

I have a 4.10 gear in the 93. Night and day difference, really wakes the car up. :thumb
If majority of your driving is in the city, you'll be doing alot more shifting. Just something to consider.

Actually an M6 could have been built with a 3.54 ('89 builds), 3.33 ('89 late & '90), 3.45 (some '90 & '91 L98 cars and on paper ZR-1 cars. There are reported unusual occurances of any of these. '92+ cars are 3.45 on paper.

Ive got 3.73's in my vert and its one narly beast with the 383 motor. Gas mileage SUCKS but it get crazy fast.
I wouldn't go over 3.73's if it was me. To be honest if I was installing this myself I wouldn't go over 3.50something. It turns over to many rpms when cruising at interstate speeds.
