I've thought about it a bit, and addressed all my concerns by talking with the Tacoma Wizard of all things slot, Tony. So it shall be Group C as follows:
Motor: Orange End Bell
Pod: Inline - any version allowed
Gears: Stock will do OR you can adjust if you prefer - my feeling is that stock is perfectly adequate for the Penguin Point track
Tires: N22 - Monte will try to have extras on hand
Wheels: Stock
Magnet: Removed - non-mag
Added ballast must be inside the car.
Suspension systems (magnetic or spring) and independent front wheels are not allowed at this time.
I plan to have loaners available for anyone that doesn't have a car.
Group C is:
Porsche 956 (any version)
Porsche 962 (any version)
Jaguar XJR (any version)
Sauber C9
Toyota 88c
Mazda 787b
Lancia LC2 (any version)
Nissan R89C
Any of these cars should be competitive and this should give everyone the same level playing field. And on the plus side, many of us probably already have some of the cars on this list.
