I received this proposal from Chris Kouba and thought I would post it here for discussion:
LMP class:
I originally intended to write up some sort of class structure for the inclusion of the modern LMP cars with and without roofs, so they would fit into something similar to the GT class. But I started getting drawn into a "Sportscar Decades" type of class, to allow all manners of hardware from similar eras to run on the track together. There are a few cars out there which would be cool to run more but that don't have roofs. Class rules would be copied from GT with the exception of not requiring a roof. Eligible cars would be from each decade, starting with the 70's. If it ran in IMSA, SCCA, FIA, Camel GT, etc... classes, it's good to go in the appropriate decade bucket.
If the decades aren't an appropriate bucket, we could look at pre-ground effects (1970-1980), ground effects (1981-1993), and LMP-era (1994-present). We can adjust as necessary.
This gets us a place to run the 908/3's, the 917/30's, 936's, Matra's, Audi R8's, BMW LMR's, Peugeot LMP's etc... with other era-appropriate cars (both open and closed roof). This is effectively our GT class broken into era buckets with the roof restriction removed.
Sportscar Era classes:
Pre-Ground Effect (PGE) Era - Full-fendered sportscars from 1970 through 1980 which ran in FIA, IMSA, or SCCA sanctioned events. Any motors (22k limit), tires, driveline configuration, or chassis material may be used. Bodies must be injection molded or resin cast and not vacuum molded. Thunderslot brand RTR cars are NOT eligible for this class, but their driveline components (wheels, axles, gears, tires) and guide assembly may be used for tuning.
Ground Effect Era (GFX) - Full fendered sportscars from 1981 through 1993 which ran in FIA, IMSA, or SCCA sanctioned events. Any motors (22k limit), tires, driveline configuration, or chassis material may be used. Bodies must be injection molded or resin cast and not vacuum molded. Thunderslot brand RTR cars are NOT eligible for this class, but their driveline components (wheels, axles, gears, tires) and guide assembly may be used for tuning.
LMP Era (LMP) - Full fendered sportscars from 1994 through current which ran in FIA, IMSA, or SCCA sanctioned events. Any motors (22k limit), tires, driveline configuration, or chassis material may be used. Bodies must be injection molded or resin cast and not vacuum molded. Thunderslot brand RTR cars are NOT eligible for this class, but their driveline components (wheels, axles, gears, tires) and guide assembly may be used for tuning.
A straight up LMP (only) class would also be similar rules, FIA/IMSA/GT cars from 1994 onward, although I'd remove the motor restriction. Try this on for size:
Any full-fendered car competing in IMSA- or FIA-based classes is legal for this class. Any motors, tires, running gear, driveline configuration, or chassis material may be used. Thunderslot brand RTR cars are NOT eligible for this class, but their driveline components (wheels, axles, gears, tires) and guide assembly may be used for tuning.
Thoughts?
