Not sure how to adjust them...
Mine tends to sort-of try to unlatch itself on the front right side. I was racing a BMW one night and right around 130MPH, I heard... WHOOOOOOSH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! So after applying the brakes with force, I pulled over and re-spun the right side for a secure latch (since it found a way to totally unlatch itself), but I notice it always trys to work it's way off when driving normal too. Now, I check it all the friggin time.
I guess what I'm trying to say is, if I find out any helpful info, I'll post it, lol.
One thing... tighten the rear bolts really tight. Maybe check to see if you can slide any rubber bushings on the screws or something.... like find a rubber hose and cut some small "donut like" pieces off that will fit around the screws, to kinda "buffer" it from rubbing directly.
