To some people that is more important, please leave a message if you want to join, Raceboy will be making a tune aswell and joining in 
Are you talking about hosting a stock race? I don’t see much tuning involved with stock cars LOL. The only adjustable part is tyre pressures.
Tire pressure’s and diff’s. Not too much tuning.
Which stock D class cars have adjustable diffs Jamie? I can’t think of any.
