My boy John took the M out to the track for it's first test and tune of my street tire set-up while I was out of town.
Video from behind:
1:26 is damn good SOW (CCW) time for a stock horsepower car running MPSS tires, PFC brake kit, and Motons. But, as the videos show, driving it still seems to be a point and shoot ordeal unless you want to deal with the cars harsh transition into oversteer. With a base line set-up now out of the way, it's time to start working methods to button down the rear end of the car.
The set-up for the car for the trackday was:
Front and Rear PFC BBK (street pads)
Moton Club Sport (rear coil-over conversion)
No Rear Sway Bay Bar
The set-up for the next test and tune is going to get a little more extreme:
Full TCK mono-ball kit
Rear Seat delete
Tuner Motorsport solid sub frame bushing
New springs and removal of the helper springs from the rear suspension

Since the stock corner entry understeer issue has been resolved, it's time to play with the camber, tire pressure, and such to find a suitable solution to add some predictability/progressiveness to the rear of the car. Do any of you track junkies have ideas on stabilizing the back end?
