^^^^^basically. But I love my bilestines and plan to stock with them. The way the factory originals are bilestine can't rebuild them but the version for our cars directly from bilestine or a retailer can be rebuilt...for a good amount cheaper over stock. For a GXP I personally believe any other brand strut is a down grade from bilestines. Except coil overs. And I have ridden in two other GXP...one had KYB's I believe and the other had ZZP drop in sets and they didn't ride as well
