Got to use these, plus front camber plates and new suspension at Hallett this last weekend. Turn in is now very "right now" without much in the way of a wait for the car to take a set. There's also more feed back through the wheel from the road surface.

One of my FCABs was shedding a piece of rubber, and bought these on Bimmerworlds recommendation-- the the damage to the stock unit turned out to be cosmetic only.
