What about do you guys think about engine brake torque? I think the brake torque is insignificant on all cars, especially on the race cars. I mean there is no need to blip the throttle while downshifitng to keep the rear stable, which makes driving easy. Especially the race cars with assumed high engine compression ratios and low inertia drive train including engine should have some noticeable brake torque. My street car seems to have more of it. I'm not saying it is wrong, i'm just wondering.
About clutch heat:
I heard many people whining about they can't drive too laps without overheating the clutch. Seriously if you experience this you do something terrible wrong while driving. From the first lap on with the new patch i didn't manage to overheate my clutch, only on puporse.
