That's interesting. If you figure the springs are shorter, and the HD shocks are not, then that means that most of the time the shocks will be compressed by the shortened length of the spring, and that will speed up the wear on them. I think.
Indeed, the Sport are shorter, therefore made for the shorter lowering springs. PLus it helps for handling
No matter what people say, whether they are right or not, I was looking for performance handling, so the sport bilstein shocks were a no brainer to go along w/ my H&R
