The best for me was the countach Lp400 you win earlier in the game, fully tuned, with rear wing set to max downforce, soft race tyres. Was easy round cote d'azure but on the deep forest you can't make any mistakes, if the 2j gets into 1st you've had it but when I won I managed to get into 2nd at the first turn (using the 2j as a bit of a buffer) then overtook the ford and did a bit of blocking on the home straight every time. You can easily outbrake the 2j and Toyota into turn 1 every lap. Just remember to lift off the gas before the crest of the hill following turn 1
