instead of the F1-2008 carset, this one is the MR2 car set, decent variety of different races, similar setup parameters to the F1s, etc but also the ability to custom paint your team's car
right now I've disabled the road cars, but if we suddenly get enough interest to mostly fill each division then I'll open it up. The difference is only 1 tire type for the road cars, they're a bit slower, and have 2 less setup parameters
here is the site where I got my custom car skin from:
MR2 World Series Liveries
glad to have some MR2.com guys on there

I'd like to get this started once we have 12-14 players
