Hi all. I'm currently using an MP4-12C in a private series, but really struggling now the series has moved to Bathurst for round 2. For the first round (Daytona Rd) I managed to win and loved the feel of the car but at Bathurst I'm understeering all over the shop, especially from Griffins to Skyline. Hell corner (t1) and the last turn are a bit of a problem but I'm putting that down to not knowing my braking point for now. I've tried making the springs and dampers a bit lower and while it's helped a tad it's not done near enough. I'm currently on a 2:05 but everyone else in the class is in the 2:02/2:03 region (I'd like to get to 2:03). So the setup. First I'll list the parts that can't be changed as part of the regs. Change Oil, Increase Rigidity. Engine Turing stage 3, Sports computer, racing exhaust, isometric exhaust manifold, catalytic converter- sports, intake tuning. Power limiter at 63.9% = 550BHP. (No turbo) Weight Reduction stage 2, Carbon bonnet, window weight reduction. Balast 161kg at -50 (50:50) = 1320kg. Racing brakes, carbon prop shaft, triple plate clutch. I currently have aero at max (100) with a custom rear wing. My current suspension setup is a slight modification on Praiano's, it was the best of the various base tunes I found on GTP- I'm not great at tuning from scratch. 80 - 85 9 - 14 4 - 5 6 - 6 2 - 2 2.0 - 2.0 -0.08 - 0 brakes 5 - 7 Max speed 224 1st 3.967 2nd 2.750 3rd 2.115 4th 1.671 5th 1.373 6th 1.174 7th 1.029 Note- I'm also finding my car bounces around off/at the rev limited at the top of 3rd coming out of some corners, any advice here? Is my 3rd gear just too long? Diff 10 / 10 / 30. I'm reasonably happy with braking, I'm both the fastest by a couple of mph and latest braker in my class into The Chase. If anyone had any thoughts or was even prepared to do a little testing for me then I'd be very grateful. I'm on DS3 with only ABS 1 and limited to RH tyres per series rules.
