Didn't have a single problem with it overheating.
But that might be because I was already used to blipping and lifting the throttle manually.
I've watched quite a few V8 supercar races and those cars can burn the clutch with a single bad start. It'll recover, but will take some time.
Don't know how fast the clutch should cool down, but it seems a bit slow in the patch now. It'll take minutes even if you're sitting still on neutral.
