Tire size and shift points will come into play on what gear you "need" and how often you intend to spray it..............i'd put a set of '56s in it if its mostly a track /weekend car and '30s if it was going to be sprayed most of the time..............also some 26x10 slicks

What track in NC would you be running at? What does your car weigh? Can you powershift? Is the car completed? A lot of things come into play. I run 4.10's with 28" tall tire. I usually run in the 8.0 area in the 1/8.


I can't seem to get 26" ET Drags to hook up.... Probably because I side step the clutch at 6k rpm......

I'd do '56s.........thats what i've got in my new combo......you can always throw a little bigger tire on it if its to short..........this is also for 1/8th. only........the torque # might make me think of the '30s though..........really depends on where its making power, i'm just guessing so take all this with a grain of salt

What's the width of your tires.....8.5".....10"? What type of suspension? I leave at 5500-6000 with 26x8.5 slicks and they hook fine!

26x15x10 ET Drags. 10 lbs of tire pressure. Steeda tubular upper and lower control arms (non-adjustable). That's about it.
