Those numbers are on worn stock tires. It is getting close to time to replace them.

Anywhere in the 11's is very optimistic. I think with more practice 12.8 is very possible, given ideal conditions maybe 12.6's.

My first trip to the Drag's I had one run with a 1.7 60' time. The ET & Trap speed were slower than my posted times though.

Drag Radials would make a big difference.
