I used these nuts on my 2015 Audi A3 Cabriolet with 19" S4 OEM wheels Audi. I've had them on my car for 2 months, rain and shine midwest. There are no signs of use at all. There were no problems with the installation either, everything rotates without problems. I would recommend a 6-point head (rather than 12-point) to avoid initial damage to the eyebolts during initial assembly. Hand-tight with a socket and then with an 82-foot torque screwdriver. pounds to tighten them. I checked the torque again last week and they were all still tightened to the initial 82 ft.lbs. First I tightened them. Will buy again anytime I need another set.
