Reply to "FR500 Rims"

Ryan,

What's important in fitting the wheels to the car is not the offset or backspace, but getting the outer edge of the tire to ride the proper distance inside the wheelwell, too far outward & the tire will rub the fender lip as it goes up & down with the suspension, too far inward and it looks wrong, plus the inner edge of the tire will rub the inner fender (when you turn the tire up front, or when the suspension travels up & down in the rear). this means the "front spacing" is the important dimension. The front space dimensions on my narrow body car are 3.75" front, 5.00" rear. I assume these dimensions will be fairly standard for all narrow body Panteras.

I've done the math on the Mustang wheels, here's the results:

THe 5.95 back space quoted for the front wheels is wrong, but that's a good thing. 24 mm offset on a 9" width wheel results in a backspace of 5.0", frontspace of 4.0". The front wheels move the outer edge of the front tire 1/4" further outward than they are on mine, which means they will probably rub the fender lip.

27mm offset on the rear 10.5" wheels results in a backspace of 5.75", frontspace of 4.75". The rear wheels move the outer edge of the rear tire 1/4" further inward than they are on mine, which means clearance with the fender lip will be good, however, depending upon the width of tire you choose, you may find some rubbing on the inner fender over big bumps.

If anything is going to cause you grief, it will be the fitment of the front wheels.
