i see you guys always mention bilsteins when it comes to shocks. so out of curiosity i thought i would see how much the 5100s cost... $100 a peice! my pro comps are half that! is it worth it? why are they so much? im interested in getting some but i mean theres just other stuff i can do with $400 while going with a cheapo shock like i did when i got these pro comps. which arent great but arent horrible. but i was just wondering....
