Shaving wheels to clear calipers
#19
#21
I have a CNC lathe at work, for facing rims.
I have 7x18 et46 lancer rims. They clear in the back, but hit the caliper up front.
to remove the least amount of material, on the caliper, you need to match the contour of the rim and use a grinding disk, then flap wheel, and while you're in there, you should clean up all he casting lines so you can paint them again.
I'm going to chuck all four of my rims in the lathe, and remove material until I can get 3mm at the closest point between the inside of the rim and the caliper.
The part that touches is the thin bridge that lives on the axle side.
I can duplicate this process (CNC!) On the others and sleep like a baby even if I sold them.
What I'm concerned about is my scrub radius.
Going from 55 to 46 is going to be tricky if I don't get the same diameter tire as OEM, but I want bigger ones and have slightly negative scrub radius at worst.
And! OEM has the front .99" wider, so I'm probably looking at spacers either way...
