Some friends and I were racing GT 300s at 500pp and there seemed to be something missing from the line-up. The usual suspects were out in force, RX-7s and BRZs all over the place, even the odd Garaiya....buy no IS350 to be seen. So I decided to give it a go, After a few races round GVS, Apricot Hill and Trial Mountain I had been tweaking away and came up with a pretty handy little tune. Well, it worked for me. Hope it can be of some use to someone else! Weight:1150kg Power:304BHP PP:500 Tuned with DS3, stick control on 0 sensitivity. ABS:1, other aids off. Tyres: Racing Hard Suspension: Ride height: F 45 R 50 Spring Rate: F 15.00 R 13.50 Compression: F 2 R 3 Extension: F 3 R 3 Anti-Roll bars: F 2 R 2 Camber: F 0.0 R 0.0 Toe: F -0.10 R 0.00 Brakes:F 3 R 1 Transmission: Set final speed @5.000 Auto set top speed to 112mph (180kph) set individual gears. 1. 3.518 2. 2.594 3. 2.006 4. 1.610 5. 1.340 6. 1.158 set final gear @ 3.500 for top speed of 152mph ( 245kph). Change top speed to suit each track by final gear only. LSD: initial 6, Acceleration 6, Braking 8. Power Limiter: 95.9% Downforce: F 250 R 400. Also ran quite well on all racing tyres at 500pp as well as at 540pp with stage 3 engine tuning. Transmission needs different ratios for 540pp though.
