I just got the K-Mac adjustable camber/caster from Turner (front and rear) about a month ago, and I am not very happy with them. The rear set did not fix the negative camber AT ALL; they would only adjust about .3 deg. The front set is okay to start with, but seems to slip out of alignment after about 100 miles or so. I have already aligned it twice! The car is pulling to the right now, and it sucks. They were installed by the mechanic who always works on my car, and checked and aligned by the local BMW dealer. I don't know what to do! They packaging that the kits were in were opened and taped back together, so I am thinking that someone had bought them, had the same problems, then returned them. I of course get the previously used set. I am not knockin' Turner here because I think that they are great, but something needs to be done. Is this something that all the K-Mac kits do, or is it just the set that I got? Should I try to return them? I already paid labor to install them and I don't want to lose that on top of the $500 the parts cost but it needs to be drivable! Any help would be great! TIA
