WRC mainclass from 2027

[RS]

i don't get why a tuner would develop a bodywork of his own instead of buying the complete car...
to sell their own car, is it so profitable to sell the bodywork, even under the cost cap?

I suppose the idea is to make it like F1 where a private team can buy the powertrain from a manufacturer but designs the chassis/aero themselves. It will be somewhat more limited in WRC though where the chassis is spec andbthe aero is limited.
