I am in the process of switching wheels on my roadster and I'm looking at the American Racing polished Cobra wheels. I would like the wheels to fit in my wheel wells the same as the ones that are on the car. here's the problem. American,it seems, only offers a 17 X 11 where the ones on my car are 17 X 10.5. The back space on my current wheels is 6.5 inches, offset is 28. What backspace and offset do I need to order on an 11" wheel to get the front of the wheel where it is now? Do I add or subtract a half inch to the backspace? I'm thinking a 6 inch backspace but I'm new at this and I don't want to screw it up. It would be a lot easier if American offered a 10.5 X 17. The front wheels are not an issue, they are 17 X 9.5 and I can match up the backspacing.
One other question. My car is equipped with Cobra R brakes. The front calipers have two open holes in each one that look like there should be a push in cover/cap? The word Cobra is on the caliper if that helps. No I didn't build the car, bought it used.
Thanks - Pat
