New to forum. Bought original 1968 AMX 390 automatic 2 years ago. Finally working on the 'refresh'.

Front completely redone. Car has torque thruster rims. Always felt real snug regarding clearance between caliper housing and rim. When i put the remanufactured calipers on, there is literally no space and rim rubs against caliper when tire is mounted and centered. Backspacer plate is fine. Car did have spare 14" Rally rim so when that is on, there is enough clearance for wheel to spin freely though not much.

If I purchase new 14 rims will I have same issue or am I better off moving up to 15# which would give me 1/2 clearance. If I go up in rim size what other factors should I be concerned with or consider?

I look forward to the advice
