Oh well RSR got a full reset after I set my laps lol.
I like the idea of a small ballast (20, 30, 50?) on the RX7 (and maybe others) to even up the cars

Nah, no ballast. It's up to people to choose the cars they like. Remember, some people race for the fun of close racing with others or because they enjoy a particular car, knowing they'll never win.
The season already is reverse grid so will encourage close racing. Adding ballast to the faster cars would just make it more likely to have a mixed grid as you coulddo juat as well in any car. There really isnt much point picking the car that cant pass others if your also likely to start near the back most races.
I also wouldnt expect many people that are a little off the pace to pick the slower cars to make sure they are even more off the pace.
