Ring and Pinion Upgrade

I have a 87 S4 with an auto trans. I just changed the ring and pinion from a 2.20 to the 89 2.54. I chiped the car and installed the rear muffler bypass. The car really performs better at all speeds. My zero to 60MPH time is around 6 seconds. Really happy spent around $3,000. If you have a 87 this is money well spent.
