If your having tire rubbing issues, as I did, with center line convo pros and lowering springs, the ride height adjustable ones are the way to go. or if you want to drag race now or in the future, they can help with slick clearance problems that you may or may not encounter.

I would go for the adjustable ones for those reasons, but if your sure you will never need them and you dont want to pay more, the non adjustable are proven performers as well.
