They are a bitch to install but I have heard great things about them once they are in. I don't find the benefits rewarding enough for me to tackle that, so I have stayed away from them.

Pros:
Increased handling
Essentially eliminates wheel hop
Stiffer ride (If that is your style)
Cheap

Cons:
Bitch to install
Can squeak if not lubed properly
Stiffer ride (If that isn't your style)
