I see what your saying, i was told the same thing, but i still think he can save $$$ by not buying a set of tires, he can make those DRs work for now, on the bottle for me, i pulled a 1.80 leaving at 2500, i never raised the bar to see if it had more, i'm sure it did, ran a 12.01 @ 115 on that pass, i'm also sure the ETs or QTPs would work better, but let him wear those DRs out 1st. lol, now i see he installed "gas" shocks on it :?, i never had good luck with gas shocks on a car i was trying to get traction with.
