I have been bottoming out only on the passenger rear tire, on bumps or if anyone is in the back seat and i mean anyone, like my 110 pound girlfriend. I have 215/45/17 tires and the eibach pro-kit and eibach shocks installed. Should this be happening? I believe it shouldn't and should be stiffer than my stock suspension and hold a load much better. Any ideas on what it is would be greatly appreciated.
