Few q's got a 03 Mustang GT what size rims and slicks can i use on this car, well thats the best set up? There are 17's street tire on there now.

Thanks Guys and Gals

i would go with 15" rim with 10" of tire...you'll hook and break ****

you defnintly need a 15' heel, how wide is up to you but alos depends on your power level. I would not go much taller than a 26" tire. what gears are you running?

USMCrebel

whats done to your cobra, and is those #'s on race gas?

I think that is most of it anyway

those numbers are on 110 octane fuel. I rin 110 all the time so thats how it gets street driven. i plan to shim the wastegate and add boost and mybe c-16 here soon. and see how it does.

USMCrebel

thinkin about it, im thinking he might need the 15" with 9" of tire, i dont think 10 would help much more.

Blownsvt

rule of thumb the bigger and taller the tire the better it will hook. but if his trap speed is not super high and not limited by gearration i would not go to a 28" tall tire stay with the shorter on for less rotating mass. It takes more power to turn the larger tire so if you are not limited by gear ratio idealy you get the smallest tire that you can hook on. i went to a 28" tire because with the 3.25 gear ratio we think it will put me through the traps at the top of 4th at around 145mph or so. have not been able to test it yet because the car is still getitng the cage put in it.

USMCrebel

yeah the balancing act of rotational mass is a bitch.....he might be stock though and that would really hurt him

Blownsvt

if it is stock, i would look at getting a 15 inch wheel and then put a 26" MT et street DOT cheater slick on it. something in about a 255 or so.

USMCrebel

^ that would be good for a bone stock new edge.
