For the price I am very disappointed in Mishimoto. They're more like $20 nuts. Are they made out of aluminum cans and painted with a can of rattles? The first time I installed it, I was very careful and used a specified torque wrench. When my wheels were changed at the shop and they took them off a couple of times as if they were already off, he would put them back into shock drive at the lowest setting. A lot of paint was peeling off everywhere. Just not the quality I'm used to from this brand.
