Trust me Deuce cutting a good 60ft on street tires is a black art.

Try this,

In my cobra I revv the car up to about 3000 RPMS and ride the clutch out the hole letting the clutch out to where I am just squeeling the tires not spinning them. I cut 2.09-2.15 60fts in my cobra all day on 245/17's street tires, and I have IRS.

Practice, Practice, Practice.

So how you liking the Tri-ax....
