i work for rimpro here in mass and this is what we do for every bmw dealer here in the new england area. your cost would be 90 for straightening. our process does not affect the finish or the strength as we use no heat. we have been doing this for almost 6 yrs now. we are the best around and are doing the wheels for a few of the ferrari dealers. any questions call me at work 888-274-6776
