Okay, here's the deal. I've had sport springs installed on my P11. But, I'm still running with my stock struts. Yes, it's a little bouncy, but for now, it will have to do. My next step is a set of KYB's. But, does anyone have an idea of how long my stock struts will hold up? I was told about 4-6 months, but it all depends on my driving. I try and stay away from potholes and bumps for now. Anyone have any insight?
