Your stock gears are 3.42s. Most of the M6 guys that do a gear swap go to a 4.10, this is a very streetable gear with an M6 trans.

Im an M6 guy and I do a lot of freeway driving, I'm stock at 3.42 but I was thinking 3.73 or maybe 4.10's since I don't hit the strip often enough to make it worth it, and at what gear are you talking about at 70? I'm going to assume 6th...

Ok i had to double check today what rpm I was running at in 6th at 70 and I was at. 1400 so the 3.73's would be much of a jump and does anyone know what rpm I would be at at 70 with the 4.10's. Thank you

You should be at 1900. Get the 4.10s and don't look back. Heck, I'm about to run 4.10s with my A4.
