i kinda want to be in that 10.5 class- my 454 will have about 600 hp plus i will spray (300 shot) the shit out if - i refill nitrous bottles (2nrwerks.com) - so the nos is not a problem. i will be happy with high 10's in 1/4 on engine and low 10's on gas. it will still be street legal and hopfully at the next track day- i already got my spot.
I think i might buy these rims - i can always use the 9.5" for rears and buy some 8" for fronts, sell the 12" ... but i need some more info on the 10.5 class -
