29.5x9 mickey Thompson bias ply slicks. best 60ft with the ss springs were 1.456 but averaged about 1.47's. that was on the transbrake. best 60 time with the caltracs so far is 1.457 and averaging low 1.46's. that's footbraking.
I had read that link a good while back, but had forgot some of the info there. will try those for sure.
