Can't find the right option. Do you have to combine weight, power etc. so just one fits in? Let's say I want to make a MB AMG Gr3 race, but you know, what I'm talking about.... Thx all and Happy Holidays!
There is no option for a one make race unless it's the Gr,X class so the only way to get close to making a one make race for any other class is to limit the power & weight to the car your wanting to use.
So say the car you want is a N-300 select that class then adjust the power & weight to match the car in that class.
Even then it will still allow some other cars within those specs to be used. Always make sure to list your car in the title as well.
