3.73s, do you think a 28inch tire is to much tire for my power level? Ty jazzer on my way to check it now.

Specific backspacing require on the 15x3.5? What size tire would be recommended there. This next question may be a stupid one but better safe than sorry, I did a standard to metric tire conversion based on the 28x11.50 tire and it comes up 292/57/15. The closest match on the ET streets is 295/55/15 that should be fine right.

Yea that would be fine being only a 3.73 you might want to look into a 27 inch tall tire.

While you are replacing your wheels and
tires I suggest going with a Centerforce
Dual Friction Clutch for you Ford Mustang.

Thanks rob like I haven't already read about that centerforce clutch 500x in the last month, why the drop from a 28 to a 27?

A 27x11.5" tire is more than enough tire for your car. Probably wouldn't even do that with 3.73s. I'd stick with a 26x11.5 or something close to that. With 3.73s you don't want to go higher than 26" tire IMO.

I guess I'll end up going 4.10s if 4.10+the bigger tire will work out better than 3.73 with the smaller tire. Would 4.10s + 28 inch tire be good with the centrifical blower setup?

Yeah, I think you will be right where you want to be with the 4.10s and a 27-28" tire. I personally think a 27" tire fits a whole lot nicer with a little less rake. Look at the 27x11.5 Hoosier QTP. Very good tire

4.10 or 3.73 would work with a 27". If you want to do a 28", I'd go 4.10 or steeper.

Well I gave Dave Guy, formerly of SGS, a call (Jason Staub and George Seager are no longer with Dave and he changed the name of the buisness) , high reputation drag racer, tuner, and performance shop owner a call and had a pretty lengthy conversation about the subject. Well I'm going to end up going with 4.30s and a 28inch tire. He explained with the size of the tire combined with the 4.30s on the street it would be equivelant to driving a stock size tire and 3.90s. Also for the reas suspension my plan was going to be MM xd lower control arms and the baseline suspension streetlaunch kit for the uppers but he has talked me into going with the team Z upper kit with rod ends both sides and double adjustable team z lowers with rod ends both sides. I'm compiling the parts collection now and will get plenty of install pictures and tire pictures once Its all said and done.
