Installed about 2 months ago. Tightened them to 120 with a blue lock. Very easy to put on and fits great. The 1.5" was perfect for balancing the rear wheels with the front wheels after the 4.5" spindle lift was installed. The spindle lift causes the front tires to stick out more than the rear tires and these spacers lock the optics in place perfectly. Drove a few 100 km with it without any problems.
