If you look at their descriptions, they say that you need all 4 statistics. This would imply that a turbo 3, fully upped tarmac car (short or long ratio) , "should" do well. In fact this would imply that any and every car can dominate.
So far people use only Honda NSX on these tracks, so we can't really be sure. I tried with my aston martin (top speed, tarmac) and it came out first with decent lap time on both in one try each so far.
Would people with high skill (mine is only 18.6) be kind enough to test out these tracks with their turbo 3, tarmac fully upped class A cars(except for honda NSX) to see if they do well?
I think stone park has already proven itself to be the dirt anything goes track as you just need a fully dirt car with the highest upgrades (turbo 3) to do well there.
I believe industrial is a bit of a fairer race for any car. The honda NSX seems to outperform most vehicles on the stone park, but I have had some luck with the ford gt40. I believe the honda holds up higher speeds through turns, and does far better with off road driving.
I always found Vector and Industrial to be a crapshoot. I've raced every variant of car on those tracks with mixed results. The only thing I can say is that my top speed-tuned LFA doesn't do well at Industrial.
Commerce is almost always dominated by GT40s and NSXs. I have both and about the same overall results, so I just use whichever one is least common in the lineup, LOL.
