I revisited a couple of V12 Supercars I'd previously had a bit of trouble with. I chose to run them on the East Course, namely the Murcielago LP640 and the McLaren F1 (with ABS off of course). I have to say, these two were a lot of fun, and surprisingly close in lap times, with the McLaren having amazing turn-in but fairly snappy throttle-oversteer, and the Lamborghini was surprisingly docile, unless the high centre of gravity pushed the rear out. Otherwise it was very quick out of corners thanks to the rear-biased 4WD, and surprisingly quick mid-corner. I had much more fun driving these two than the Ferrari Enzo I tried next...
The Enzo, by comparison, had a lot of power, but an explosive torque curve and a tendency to waste time by snapping into wheelspin and smacking the rev-limiter. Through the second half of the double-chicane the Enzo wanted to understeer wide of the exit, where the McLaren's front end stayed planted, with a hint of mild oversteer. I couldn't brake quite as late in the Enzo either as the other two. It was much, much easier to post consistent laptimes in the McLaren and Lamborghini than the Enzo.
In short - I reckon the East Configuration is a great place to benchmark stock Supercars, with a good combination of high-speed sweepers, long straights, hard braking zones, low-speed corner exits and tricky left-right transitions.
Oh and the laptimes?
Lamborghini LP640 1:30.8
McLaren F1 1:29.8
Ferrari Enzo 1:29.7
