any1?

I have not... My car is lowered s I do not think I would be able to slide that under my car with my floor jack under there... It would be a tight squeeze I would think on a stck height car as well...

That looks pretty good. Many folks use a hockey puck in the same fashion.

the hockey puck seems like a good idea but how do you modify it?
