The car still has 528HP, no oil change. Racing Hard tires, capable of 1:25s at Brands Hatch GP and 2:08 at Bathurst.
Suspension F/R :
Ride height 70 70 ( go no lower than 65 65 on bumpy track ) I used 60 60 on Brands Hatch.
Spring : 11.24 15.97
Damper compression : 4 3
Damper Extension : 4 1
Ant Roll : 2 2
Camber : 2.4 0.0 ---important - rear at zero gives max possible grip on lower speed.
toe : 0.00 0.00 ( neutral as possible )
Camber hugely affect front and rear grip balance, due to the quirk in camber - zero camber = max grip. Higher camber front to compensate the too much grip at the front chassis.
Brake Balance : 1/10, yes, use this, 5/5 by default do not represent actual bias, the car bias parameter always has front bias, completely different than in GT5. Check by using 0/0 balance and brake without ABS, front will still lock first. R8 LMS has very front bias balance, 1/10 is used to make the rear more stable ( minimize too much weight shifted forward )
LSD :
Initial : 33
Accel : 30
Brake : 30
Use 2 way with high preload to minimize drastic changes during trail braking and exiting corners. Keep the initial high, lower accel and brake if deemed too extreme. I would recommend 24 accel and 24 brake. If the car power increased, lower to 18 accel and 18 brake.
Lastly : Aero
Aero is for medium and higher speed cornering, you can use max aero 400/900 for technical and non high speed tracks. It's a matter of finding balance, always try ot have at least 450 to 500 gap value.
So, if using 200 front, set 500 rear; 400 front ( max ) use 900 rear ( max ), if the car becomes less responsive at high speed, reduce rear by 50
NO ballast used. Keep it at 1250kg
With more power, I would recommend full aero, increase front camber to 3.0 and keep rear 0.0. Increase toe in at rear to 0.16 or 0.32 and zero toe at front.
Hope this helps to make R8 LMS enjoyable.
