What's the best way to trim the lug height on a track. I have a SeriesIV that has 60mm tall lugs, I want them 45mm. I tried doing some with a sawzall and it worked for most of the lug except for the last little bit, the compound is to soft so it wouldn't take off the last bit. It also wasn't the straightest cut. I'm going to measure and draw a straight line, anybody got info on what to cut it with.
