i did a search and what i found was just which brand people like, but there was one topic that did help. It mentioned something about GroundControl having different sleves for different shocks. Example, a different sleve for stock, koni, Kyb and so on. Is that true? Also i was wondering if i could mix shocks, like haveing Koni up front and Kyb in the back. The reason being is because KYB rears are much cheaper than koni, but from what i hear koni seems to be the best.
