And the rates are based more for handling, almost like a "track day" type of kit. It should eliminate the need for the stupid bump stops, since the car won't roll as much. Also, we have to remember that the Bilstein HD's won't drop as much as stock type of KYB struts, so I am kind af basing this kit around the bilsteins, which I am partial to lol. Lifetime warranty+internal bumpstops+race proven technology=win in my book.
