Reiza appears to work the best here in terms of grip. It's probably excessive even, since the grip seems alien-like at times. FEx and CART are abysmal, understeering heavily, cornering speed greatly reduced, brakes feel underpowered. These two feel broken here. V12 better, but still so-so, it's ca. 10s slower than Reiza in my exp. F3 also understeers more than usual and is more slippery than normal (especially off throttle mid corner).
I think the track would probably need to have the grip revised or optimized to be compatible with different cars...
