i would think it would have to depend on your gear ratio and also if you have an automatic or 5 speed. the automatic will kick down but the manual you have to know what your rpm's will be and pick the right gear. you wouldn't want it to be at a speed that has your rpm's too low. with 3.73's and doing rolling starts from around 4000 rpm's works out to 25 in 1st, 45in 2nd and 65 in 3rd. go to the analyzer and put in your gear ratio and tire size and it will give you the rpms for each gear and mph from 1st to 5th. i would think that around 3500-4000 rpms would be good rpm's to do rolling starts
