just bought an 89 gt

I just bought an 89 gt from a close friend of mine and love it. Was wondering if anyone would know around what i would run in the quarter??? car has bbk headers, x pipe no cats, cobra upper n lower, 180 degree thermo, 4.10 gears, e303 cam, 1.6 rockers, pulleys, cold air intake, aluminum heads, and thats about it. Havent had a chance to bring it to the track, but its deffinately the fastest car ive driven.

id be willing to bet low 13s or high 12s!? maybe anybody agree? Maybe even low or mid 12s!?

thanks for the reply, another question is what size tires are best for the 89's??? It only has 225's on it now and just spins, 265's maybe??? Just dont want to go to big and rub.

oh im not sure im not too smart when it comes to tires you might want to ask highflow 5.0!

You didn't say if it was an auto or stick. Either way I say mid to low 13's auto, high 12's with a manual depending on driver skill level.

I'd say no wider than 245's or your gonna rub on the slightest turn.

245 upfront is all your gonna get w/o rubbing. The back without changing suspension up a lil 275 can be squeezed.

Squeezed is the word!

If it's 4.10's, I'm gonna GUESS it's an auto. If it's an auto....13.3's. 12.8's if it's stick and if it's stick with 4.10's.....good freakin luck getting it to launch. A buddy of mine from Fl has a 95 Cobra with 4.10's. I don't remember his mod list but he walks light modded/pullied 03 Cobra's pretty easily. His MPH at the track is good for mid 11's but he can't hook for SHIT and has a good amount of suspension work. He's going to 3.55's to see if they make a difference. So yeah if it's a 5speed, you're gonna need ALOT more then tires to hook.
