I have a Boxster S 2003. Recently, while driving it started to make a weird noise, upon inspection I discovered there was a nasty cut on the left rear tire( see pics ). When I got home, I took the tire off but I couldn't find anywhere that would be rubbing against the tire to make that nasty cut, the closes thing was strut/shot. Could this be a Strut Failure or is it something else?
How much does it cost to replace the struts dealer vs indie shop?
Any info greatly appreciated.
