Hi Ward.
They slipped right on my car. I did use lots of anti seize just to be sure they wouldn't stick. They were on my car for about three years. Try switching from side to side or rotating 90-180 degrees.

Jim,
I'm finally getting around to switching the wheels I purchased from you several years ago. I got some Hoosier tires and going auto-crossing tomorrow. I'm surprised at how hard they are going on. It is like the driver pins are a really tight fit. Did you have any trouble with this and how long were they on your SPF? I'm lubing them up best I can. Thanks, Ward L
