whats the best 60ft for a RWD on 20'' street tires? I cut a 1.79 on street tires right off the street with no air pressure removed...just curious how it compares to others out there...

My truck used to do 1.77's constantly with stock RSA's and a 3000 vigilante. It would very rarely spin.

that aint half bad either consider Kumhos are a pretty hard compound...
Yeah, they are a 420 treadwear rating. I bumped them down to 20 psi at the track. Daily driving I put them at 32 psi.

1.7's are not too uncommon on 20" street tread, i know of several peeps who have done it, incld. myself, but that was with the help of n2o... Just takes the right finesse about 23lb of air pressure and some sticky on the track...
