This might surprise you, but you might not be the only one here who knows something about tuning a virtual race car. By first doing hotlaps is to find differences in speed between these 3 car makes. Just to try see if there are bigger differences in "core phycics". What I found out is Porsche has best top speed, then Vette and lastly BMW. At Le Mans top speed is very important as it's the primary weapon to keep others behind at track. It's also very important if you're stuck behind someone. Increasing preload to max is going nuts. In this case it helps with the lift-off oversteering, which is a biggest problem after latest BoP, but at the same time it's not good at all for accelerating out of corners - fast corners especially. It's fixing one thing by sacrificing another - which isn't best thing to do. But I agree with you, aero balance is off at the moment. Why I'm trying to keep wing 1? Because with wing 3 Porsche has faster top speed than Vette with wing 1. And I don't want them to overtake me from left and right. THAT is the problem. Let's hope performance of cars across a stint is balanced. Time will tell.
