Okay...I accept the fact that they spin, but that is the nature of the offset mounts and not fitting into the stock recesses.
What I am questioning is how is this a problem? They still do the same job right? They are no less safe than the stock setup and if they become one, well let's say that if you have your car airbone in such a manner you will have other problems.
Personally I still see no true justification for these other caps and I will stand by that until someone provides a reason other than them spining. And btw....taking the car to the track 4 or more times a season since I've had these and probably driving the car harder than 90% of the people on here with no adverse affects counts for more than anything in my books.
