FE Green in the FOX is a blast, I enjoy the whole track.
The XRR pretty much anywhere.
Least favourite are the longer SO tracks, walls suck :'(
For me favourite car/corner combo changes with time, setups, and with patches. But I would say that for now, I'm kinda hooked on the FO8 at Westhill. I love gassing it up out of the chicane after the second split, really turning it on the throttle LOL, the rest of the track I could take or leave
XFG in the current WR setup at the second chicane of Blackwood GP Starndard (after the corner @ end of straight). I love that corner, black lines everywhere!
Think i haven't got overall favourite but... The whole middle section of SO Long with the FXR is just great, especially right after the 1st split, the bumpy corner when the track meets the Sprint 2 layout, and after hairpin the corner which turns from the "town part"... the uphill - 90degree corner with some airtime or two-wheeling.
