I have M&H racemasters 325/45/17 on 2003 style cobra wheels by American Muscle.
Will they fit on my 2010 GT500? They are brand new mounted and balanced. They are basically free, so don't flame me for buying without trying.

Anyone? I hate to mount them and rub the fender.

28 x 11 fits on my '07. What's the height and width of the tire? Mine is the 325/50/15.

I run a 28x12.5x15 MT ET Street. I had to cut away the factory brackets in the fenderwell to make them fit. Along with cutting up the rear sway bar bracket to get the 15x10's to fit.

Not yet. It's been really crappy weather here. I am a little afraid. I don't want to start cutting fender brackets. When it warms up I will take a closer look and try to mount them. I will post the results and maybe pics if I can.

That would be great ! Waiting 4 your results before ordering mine.

if the wheels are a SN95 fitment rim, they will fit on the car but the tire will likely extend past the wheel well.
do you know the BS and offset?

Ok, the answer is they do fit. No rubbing. No mods.
The second question is do they change the effective rear end ratio with the larger diameter tire and what does that mean in 1/4 mile times?

stock diameter / new tire diameter = X.XX
27" / 28" = .9642
gear ratio x X.XX = effective ratio
3.55 x .9642 = 3.42
