OK there seems to be some confusion with this in all the different games. I am of the understanding that in any of the mods including WTCC the higher the wing setting the greater the downforce hence drag. So at Monza you may run a 2 rear but at Pau you would run a 5?? In the wing cars you can run from 0 to about 32?? Same applies here no? Just that I have used some setups from Simbin where the differing classes seem to have different trends> GT's would be low downforce and a WTCC car would be high? Just wondered if all the classes run the same wing engine?
