Torque: 397.8 ft-lb at 6500 RPM
Power Limiter at : 100%
Weight: 1250 kg

GT AUTO
No oil change yet - feel free to do so.
Improve Body Rigidity ( optional - not installed in this build ) - there's no bad side effect of this, highly recommended.
Wheels : Stock
Car Paint : Stock
Tuning Parts Installed :
Racing Exhaust
Suspension Fully Customizable Kit
Adjustable LSD
Racing Brakes Kit
AERO :
Downforce Front / Rear : 350 / 730 ( STOCK - please adjust according to track ) - try to maintain 250-500 gap value between front and rear or adjust to suit your style ( less gap will make the car looser in high speed + slight top speed increase less rear used )
LSD - 2 way high preload - improved
Initial Torque : 30
Acceleration Sensitivity: 22
Braking Sensitivity: 46
Higher braking to reduce rear chatter when coasting and trail braking, reduced acceleration to reduce understeer and sudden changes in traction when under extreme load, initial torque optimized for balance between stability and response.
Suspension - improved
Front, Rear
Ride Height: 75 85
Spring Rate: 14.45 20.50 ( medium setup )
Dampers (Compression): 5 4
Dampers (Extension): 4 10
Anti-Roll Bars: 6 3
Camber Angle: 0.2 0.0 ( alters the balance of grip between front and rear - higher camber up front reduce the front sensitivity to steering to make it less twitchy ) I recommend between 0.2 to 1.2 - adjust to style and track.
Toe Angle: -0.10 0.10 - increase rear toe in if want more stability, I recommended no more than 0.24
For Spring Rate F/R- alternative soft setup : 11.24 / 15.97 or hard setup : 17.94 / 25.47 or super hard : 19.64 / 27.88 -TESTED
Transmission
Stock gearing, only alter final to suit track.
Brake Balance
9/5 ( personal BB) or for ABS 0 wheel : 3/2, for ABS 1 - feel free to use your preferred brake balance.
Recommended setting for DS3 user :
Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 5/4 brake balance as starting point.
This tune is made to help drivers tame the car, as the stock base setup is not very friendly and has too much front grip bias.
The camber quirk of zero value giving more instantaneous grip is used to alter the balance of the car when coasting and in mid corner to exit ( sustained grip during cornering seems to be fine and works as it should with camber changes ).
Brake balance set to rear bias helped the car under braking instability, the 2 way LSD also helped giving better traction both on and off throttle. All it takes some minor adjustment and the car becomes much better to drive, stable, and quick.
Tuned and tested at Brands Hatch GP, Bathurst, Silverstone Stowe, Apricot Hill, Nordschleife and Silverstone Full Track.
The R8 LMS Ultra Team Phoenix ver 1.03 able to lap Brands Hatch GP at 1:23s easily ( PB 1:22.2xx stock gearing, stock aero with the above tune ) and Mt Panorama Bathurst at consistent 2:05s ( PB 2:04s ) using stock aero + gearing - same tune above ( LSD and suspension ). All on Racing Hard, stock power no oil change.
The tune has also been tested with max power setup at over 900HP, works great, adjust gearing, aero and spring rate according to the track, enjoy
A video of the car when tested during tuning session ( 2:07 at Mt Panorama ) ver. 1.02 tune :
UPDATE : Suspension has been revised, better stability and more responsive steering
UPDATE ver 1.03 : Suspension and LSD has been overhauled, now it's several seconds faster around Brand Hatch GP and Bathurst on 599PP. Stability improved mid corner and exit, entry also improved a bit. Understeer has also been reduced.
NEW UPDATE 1.04 : Improved front damper setup to allow better weight transfer and better compliance on bumpy track.
Added Note for top speed run ride height and spring rate :
Hey Ridox have you noticed the R8 LMS Ultra having a tendency to sway at high speed with stock downforce?
I went to do a top speed run and brought the downforce all the way to minimum but at around 220-230 mph it sinks to the front and the sways uncontrollably. So I brought it back to stock and it did the same.
So on a hunch I minimized the front completely but brought the rear up to 500 and it disappeared until you get to the banked turn where you have to reduce speed to around 220 mph or you will lose control. Anyway to sort this out or am I right on the money?
This is on Route X by the way.
Easy fix : increase ride height to max, you see, when running at very high speed, the low clearance causes the suspension to bottom out as the downforce pushes the car downward Try this : set lowest downforce front and back, keep all else the same as my tune above, except max ride height. Drive to top speed at SSRX with full power 900+HP, you will notice the car gets harder to steer as it reach top speed, and no more nasty spins ( try lowest ride height for giggles ) -- BEWARE with highest ride height, meaning highest drag - lower top speed and heavy steering
ALTERNATIVELY : Set hardest spring rate set on my tune : 19.64kg/mm front and 27.88kg/mm rear, with min downforce ( allow highest top speed ), set ride height to 80 front and 80 rear, with this setup I can top 400kmh and maintain 390+kmh at the banked turn with great maneuverability If want to experiment, lower ride height both front and rear by 1mm until you find the sweet spot
EDIT : Testing 70mm front and rear ATM, with min DF and hardest spring set as on tune post
-- result : 407kmh top speed, stable on straight, weaved and changed lanes without drama , but unstable on the banked turn when moving up and down the lane -have to be extra careful when moving from top to bottom lane I would increase to 72mm to be safe.
Testing 60mm front and rear :
-- result : stable on the straight, but a bit nervous in quick lane change. 414kmh top speed - not bad. BAD news, spins immediately when entering the banked turn at full speed, highly unstable there.
I would recommend ride height of 70mm as minimum, with extra care when changing lanes on banked turn, 72 or 75 would be my best bet.
This is good experiment, looks like the aero works great in 1.03
BTW, this is all done on the tune posted above ( with max power ) and Racing Hard tire.
