Ok then! This is for "zero aids" (TC, SRF, AS, ASM, ABS = OFF) and works for my style. Initially I tried the smooth grip driving style and I grew frustrated so I drifted and it seemed to drive better so I developed this car to suit such style, drive it like Colin McRae.

Much to my surprise the camber seems to work on this car. With 0 camber I struggled to turn the car on that sweeping left hander on back uphill section but with some camber it makes it nicely. Also with some camber I can drift on the bottom section through those twisty bits without losing much time. It has a lot of traction so use the brakes to slide and rotate the car then full throttle on slow corners. I'm driving more SRF style than ever.lol
edit: Reason for choosing this car was that being wagon having extra roof bit at the back, at higher position, which should pull the rear end to side to side when cornering, should provide more rotation than its sedan counterpart. It has better weight distribution as well. Obviously it's bit heavier, and heavier at the back (and at higher position), which is better.
edit: I'm not sure whether twin-plate clutch is better as this course involves a steep hill climb. The description says the 3plate clutch suffers from engine rev drop on uphill. I can't personally feel any difference of the two. I increased the torque purposefully to deal with hill climb so I thought the lighter and rigid clutch would work better but I'm not sure...
