Wheel & Tire Fitment Question

[MustangCar8]

Through a friend I have an opportunity of obtaining 19x8.5 and 19x9.5 9.5J Width rims (5 bolt pattern 5x4.50 & 5x114.3) offset 30 with 275x35x19 tires. Frankly, the tire/wheel fitment issue is a bit confusing and I've tried to educate myself as to whether these would fit my 06GT via this forum and various vender websites but I can't seem to find a definitive answer. Could someone provide me guidance or steer me in the right direction?

That offset is a bit low for the rear wheels, so they may stick out some. Most 9.5" rims are using an offset of 40mm or more, so that's a little under a half inch difference. 5x4.5 and 5x114.3 is the same bolt patern.

That is a great question I have been looking for how wide of a rim I can go with without having it stick out past the fender does anyone know? Along the same line I was also wondering about rotor size vs. rim diameter. I want to get a larger rotor and was wondering how big can you go with an 18" diameter rim?

The 14" brembo kit from ford fits under an 18" rim, as does the stoptech 14" kit and probably most 14" rotor kits. 15" rotor will likely need a bigger wheel (19"+). Of course no two wheels are created equally, so make sure to check brake fitment prior to purchasing. Personally, if it's mostly for looks (you don't do more than open track events) then I'd go with the ford kit, more than enough brake for anything short of a true race car.

I'm not 100% sure on how wide you can go with what offsets, but I know 9.5" with a 40-45mm offset fits on all fours, there's a whole thread on wheel fitment.
