My next thing to try, is to heat up the tires alittle more, they get real nice & sticky... dump @ 2,500. Maybe this time I might actually shed some weight, my only weight reduction was the floor mats
My last run my 60 sucked cause I started at the tree @ 2,000rpm's, then on the second yellow I brought it to 2,500 and slipped the clutch had alittle bog off the line, but the car came back nice and quick. Provided I hit the tree right it should be an excellent launch. These Sumotumo's at 25psi were great!
