of course check balance,and send in related parts. If you drag race,plan your gears and et before you start. The O/drive makes it "streetable". Ive run gear ratios from 2.7 -5.57,,,what are your intentions?When I was young it was fun street driving with 5.13s and a 4speed,now I use 3.50s and a 5 spd,you decide?
Steeper gears are most notice able when you launch the car.
How quick is this car going to be?
