Thanks for the responses guys.
I know a bit about drift tuning from GT5, so what I like to do is go out stock see what can be done and then make set up changes to suit. The thing with this game, though, is that the tuning menus are all in relative terms. How much negative camber is 17? Its so disappointing because this game has such good tuning options, just the way you tune it is so strange.
Anyway, I played around with the settings a bit, left the steering lock as it was, moved the brake bias forward, and significantly stiffened everything up. I was quite shocked to see just how street this car was tuned, very soft from the factory, and Ive been in RX-7s, and there is no way they are that soft. Anyway, applying my knowledge from GT about what suits my style I made the set up considerably stiffer, about three notches more on the front settings for all the suspension and about 2 notches more for the rear. I find that having the front slightly stiffer than the rear makes the slides much more manageable.
So after I did all of this, I went and practiced on the Hazyview 8, a circuit that I forgot about from Shift 1, set the laps at 20 and off I went. I managed to get my personal best per lap up to 229.
This was also when I noticed a bug in the game, I played a couple of these 20 lap events, and the first time I played with one opponent and it was set to same class, so I was drifting against an R8, which was very odd. Anyway, the first time I raced it the guy got a score of about 2XXX, meaning that he averaged about 100 or so points per lap. Then I finished and won easily by a thousand or so points. But then I went and played again, with the same amount of laps and only changing the time of day to night time. Only this time, the guy only posted a score of 120. Which would have only been equivalent to one lap by the standards he set last race, even though the race distance remained unchanged at 20.
Very odd indeed. Then I went to London Millennium because I remembered that track too only to see that they had changed it. And the same thing happened, it was a 20 lap event in the dark and the guy had only posted a one lap score, instead of a 20 one. So I won that event easily too. As well as getting a personal best of 1197. (So close to 1200)
