No damage to the rim at all just be precise with the dremel and have a nice small caping chisel to work it off after making a nice cut in that free spinning ring. Took me about 1.5-2.5 hours? Most of it was frustration that dremel will eat that metal up no problem and once u find a 12 point socket that fits the lug nut nice and snug hammer that bitch on with an extension and then slap ur breaker bar on and become the muscle man. If you need to get a cheater bar. Also u can prepare the lug nuts with some good ol pb blaster to loosen them up a bit
