During installation I noticed that the tip of the glans has dimples on the front wheels. Then the tip of the acorn began to rust. At the time, that didn't bother me. Much better than factory nuts with stainless steel spacer caps that don't fit snugly. After a few weeks, the nuts loosened. The rear wheels fit well. This is an all-wheel drive SLE with factory 20-inch wheels. One front hub has been replaced with a Moog, the other is still stock. Nuts should be slightly longer than 1.50. Be careful.
