I already had 1/2 spacers installed so I bought some .625 spacers but the right side is still very close. I'm afraid that when turning the wheel may flex and hit the caliper. So how close can the wheel be ? Can't put much more spacer on cause the front tire will hit the fender.

I am guessing you don't have the caliper installed correctly. The parting line on the caliper should be lined up exactly with the center of the rotor. I have aerospace on my 68 Camaro and have no issue with clearance to the back side of the front wheel

Mike, I will look at it again when I get the chance but I had to put a lot of shims behind the caliper brackets to get the least amount or drag especially on the passenger side. I ordered some .750 spacers today to try, won't have them till next week. After I put the car on the ground I do have more clearance between the tires and the fenders than what I thought. I will double check everything this weekend.

Spot on Mike. I had the left side lined up perfect but the right was off abit. I took some shims out of the right side and got it lined up. Still don't have the clearance I would like but should be enough to not cause a problem.
