I have the s912ti's on 1080's and for the most part they are tuned nicely and my boot is tightly locked in. Only thing tho is with slight effort I can 'wiggle' the front of my boot. My boot will move a few cm's to the left and right. I tried tightening the screw on the very top at the front (its a flat head) and it helped alitte but not enough at all. Even when I make the binding smaller it still happens. Any ideas?
