Z4M Coastal Empire PCA DE 9/22/12 Roebling Road Turn 9 "fun"

Hey guys another weekend another track day for me Had a good day trying out my new 255/275 PSS setup and got moved up to the Black group. Just need to bump my front camber up to 3.5 from 3 and that pesky understeer will be minimized. It wasn't all good times though. This is a video of the second session which demonstrates the laws of physics quite nicely at 12min mark. I have a bad brake booster check valve which can apparently cause an engine limp mode where the yellow brake light illuminates and the engine cuts power. Watch what happens when your car unexpectedly engine brakes at 100mph loaded in a turn by a 1300 foot wall......

Thanks, I have never been so happy to toss it into the grass , on the next lap I saw my skid marks were a whopping 4 feet tops,away from the wall... That turn is the place were cars go to die if you try to be a hero and stay on track if you lose it.The old girl is in the shop getting worked on as we speak.
