It definitely gave me back additional rear suspension travel... Now my rear driver's side tire rubs I guess I just need to roll the fender lip when I have some time. It definitely feels better over bigger bumps (except for the minor tire rub).

If there is enough interest, www.motivational.net may produce some more (I think I bought the last set). Same company doing the CF hood GD.

Picture from their site... the version I got was slightly different...
