I trimmed mine. The thing is, I trimmed both my front and rear to my liking. I figure they would break for sure. Well that has not happened and I have had some vicious tumbles. Just this past weekend, someone clipped me as I hit a double at full speed. I think my buggy bounced and flipped a good 20 feet and nothing broke (soft outdoor wet clay). So if you need to grind a little, I am sure it will be fine, just dont go crazy. Also, fo those of you using C hubs and still scraping up your shocks. Just mount the hubs on the backside and put 2mm washers under the stud. You wont ever rub and moving the link on the horizontal plane does not seem to affect handling at all. If you are using the A hubs and rubbing, look at the exotek rear hubs. The vertical ball stud positioning helps to move the link further away from the turnbuckle. I use Lunsford turnbuckles which are thicker than the AE ones, so a few shims are not cutting it for me. I tried .090 shims on the bottom, cut the tower and used the Carbon A towers and still rubbed slightly with the lunsfords.
