I'm doing some calculations for determining the optimal rearend gearing. I do not have my Camaro as of yet so if someone could measure the outside diameter of the stock SS 20's I would appreciate it and post my results. Please feel free to use another method of measuring but here is my suggested method: Draw a line on the bottom sidewall of the rear tire and then another line on the pavement that aligns with the one on the tire. Then move the car until the tire completes one full rotation. Mark that spot on the pavement and measure the distance between the two lines in inches. Please be as accurate as possible.
Thank you in advance
Greg
