How about classic body shells, I got my XU1 Torana shell all done in purple and I just scored a GTHO Falcon shell to wrap around the fusion.
Why does nobody race these, is it about aerodynamics?

maybe run a clear body shell class, see how tidy you can make the inside of the car.

Or a drift class, we all run super hard rubber or foam at the Hill
and drift away....

Demo derbo would be fun. Oh forgot, Mini covers that.
