1.72 best with 275/50-15 nitto dr mounted on ten holers. This was on stock suspension minus jegster lowers and a well preped HRP. Usually pulled 1.8's. Now with c-springs, kyb non-adj. , and mega bite jr lowers the best I pulled was 2.0's on a very slippery non-prepped track in West Texas. Now I have since switched to 150# coil overs with skinnines up front, but have yet to get track results.....
I like the nitto's for a car that will see more street driving than track time. They have good tread wear. If you don't care about tread wear, go with BFG or mt drag radials because they simply hook better.....
