i ran a 17.2 once when my car was stock and i was learning to launch....AT OSW!!! that place is a joke for traction...

but yeah ive ran some 16s in my heyday. i think i could muster up a 15.9 if i had good tires but im gonna have to settle for mid 16s if i ran haha.

i should have brakes completed by track day....ill out brake you haha. this is track day 7 right? i figure by track day 10 or 11 i should hopefully be close to jumping from 16s to 13s.
