I would like to run the 1/24 Gr. C class as well.
I like the idea of the RevoSlot 1/32 Alfa, Escort, and rumored BMW 2002tii. Run this later in the year to get additional liveries, but buy early if you like what is for sale in October 2022. Run it as 20 laps on the rally track, then without replacing parts go 20 laps on the green lane of big track. ALL cars must have sufficient ground clearance to not rub the chassis on the track tape including if they jump the mound.
I am a strong proponent of a 1/32 TransAm race with 3d chassis. Maybe limit to less than 25k motors for slightly more realistic speed.
I can go along with the traditional slot.it Gr. C race if we are provided the specs to run the National Champ Jaguar mods on our existing cars, or limit the Jaguars to the tires and track width that fit our existing cars.
I also like the LeMans Ford vs Ferrari challenge race and allow other cars from that series that we not so famous.
Run Monte Carlo in next decade. Maybe two classes with the slower class running tires limited to 8.0mm this time. If you look at the reference I cited earlier in the forum you will see there were multiple classes run in the race.
