This car is a lot superior to any 600PP road cars . Excelent at 700PP against GR4 cars , a real pleasure to drive .
Advise: Even at 700pp you can’t drive like mad. Need to be care about your balance , no late braking entering a turn… Respect. . Very reactive to any inputs under throttle , wheel and brake .
Well , i did an experience against GR3 at SPA. Same lap time at 730PP with racing hard tires , around 2:18.xxx . But it’s extremely wild. 
Here are 3 settings , 600PP , 700PP and 730PP. No gearbox settings , do your own . Easy no problem.
Only the 730PP , you’ll have to add a mid range turbo compressor.
