With my beetle previously 944 suspention/disk brakes, t4 motor, stripped interior , I was running D-Modified in scca, OSP/OSPU in NASA or in SCCA when allowed, and OSPU in the Northwest Hillclimb Assoc.
With my current subie ej20 turbo, bus tranny swap, and turbo 944 suspention and brakes, I'll be running in Modified or Unlimited in the Redline Time Attack series, competing with a bunch of cars that never expected to have a bug running them down on track.
