Best way I can tell you....
*22-24psi in the tires...
* Good burnout through the water box (rear wheels only get wet NOT the front)
* Track Mode
* Stabilitrack off
* Make sure you barely clip the 2nd light on the tree when staging...
* When ready (Now this all happens in miliseconds) Let off break so it just starts to roll and pedal to the floor... If your track is prepped well this formula should get you at least 1.9
* Practice!
I have been racing for years and it took me 3 to 4 track days to get it down pact...
Look at my video I posted maybe you can see some of the steps in action... In my video I had on Nitto NTo5 same size 275 profile and yes they are a tad stickier than stock but honestly not that much...
