Just picked my car up from Stage1 Automotive. I had a Gear Vendors Overdrive installed. With 3.42 gears and 27" tires, my effective gear is 2.62 when in overdrive. 60 MPH is a little over 2000 RPM, 2300 RPM gives me 70 MPH. Rob Chilenski did the install, and all he needed to do was cut and reweld the crossmember so that the trans mount would be lower. A few very small dings in the floor. No exhaust modifications to my X pipe. I managed to pick the car up in between storms this morning. Testing will have to wait for nicer weather. The car felt great.
