I woke up this morning and realized when I test fit the spindle/rotor/caliper assembly yesterday, I used my spare tire/rim, which did not have the magnum 500 center cap installed. Thought I better test it just to make sure there were no issues seating it with the cap and rear bracket installed that holds the cap on.
I didn’t have an extra cap, so decided to use my passenger side front wheel for the test. Removed that wheel from the car, slid the assembly into place and installed 3 lug nuts to torque it down to check for any interference with the cap. It still fit just fine, so that was a relief. Decided to give the caliber a spin around the rim and wouldn’t you know it but something was rubbing...
Cap bracket installed, no problem here:
Note rub mark on caliper...
and on the adhesive wheel weights on the inside lip of the rim...
Was a little disappointed but after pondering for a couple minutes went and verified my spare rim that I tested with yesterday only had a wheel weight clipped to the outer rim edge, which is why I didn’t notice the issue yesterday.
I checked the other 3 rims on the car and both rear wheels have similar placed adhesive weights on them, but the rear SSBC brakes do not rub on them (smaller rotor assembly). The other front wheel only had a clip on wheel weight on the rim edge so that won’t have an issue.
Made an executive decision to put the spare tire/rim on the front and demote the rim that I tested with the rub this morning to the spare... problem solved!
If I ever need to put the new spare on the front of the car, I’ll scrape off the weights and drive it home without them...
