Um I don't have this car but having the Traction Control set to 5 in my similarly powered skyline helps the wheelspin. I noticed with some cars like the Elise 190 having ASM set to its default value helps the car turn better, although with most cars I like it turned off. Also messing about with the camber and toe settings usually can help.
Here are some settings I try in a few of my cars to try and help the handling better, but as each car is different I can't guarentee them being any good so it's best to back-up your old settings.
Spring Rate: Have the front quite soft and the rear about 2.1 higher.
Ride Height: Keep the front as low as it will go, and the rear as low as it will go or as high as it will go.
Shock Bound: 6,7
Shock Rebound: 7,8
Camber: Dunno, I just set it random and hope it works.
Toe: Same as above.
Stabilizer: 3,3 or 3,4
LSD: I usually just copy this from the road setup settings at gtvauly and then round the numbers to the nearest 5 or 10.
TCS: 3-5
everything else off
Tires: T4 or T6 but T7 are probably best.
Anyway as I said these settings aren't universal so I hope they work, but if they don't please don't flame me, I'm not an expert when it comes to car setups and it's likely that we have different driving styles so what suits me may not suit you. Good Luck!
