This car i must admit is a royal pain to setup for slow tight corners, in the fast corners and straight lines its deadly the AI @ 90 cannot keep up, but throw in the tight corners, the front brakes lock to easy and if i adjust them from 60/40 to 55/45 and decrease pressure to 80% the car does not slow down nowhere near as quick as the AI,

Also it cannot keep pace with the AI in other cars in tight corners.
ive stiffened the rear anti roll bar from 0 to 15-20 , if i push for more then it will over steer out of the corner, The front ARB is set @ 50

the Rear LSD is set to;
clutches @ 2,
Power ramp @ 75,
Coast Ramp @ 20
Preload @ 60nm

Caster Angle is at 6.5

Front Springs @ 298
Rear @ 114
Dampers are set to match the springs High bump\rebound at front, softer at the back.

Front downforce @ 2
Rear Downforce @ 1

Soft Tyres,
Track at 65 fahrenheit

Ive tried a lot of things to get a better turn in without the back end sliding out, with not much success

Does this car naturally understeer?

What car did you use in the Prototype C Championship in career mode? did it have a similar problem?

Which Sauber? Either way, these cars relied on rear downforce to activate the underbody diffuser due to high levels of interactions between the two parts. If you don't have the rear wing working hard, the diffuser won't work hard either. Go 2/16 aero, especially if this is not the LM car.

Hey, your platform says PC, if it is have you tried other setups in TT? If your platform is XBOX or PS4 you can fix it. Ok, so I assume you are not on PC, just looking at your setup and the problems you are describing it looks like your rear downforce is low for this car. Here is a SUGO setup for example.

254477
254478
254479
254480
254481

If the rear downforce is low, i thought this would create oversteer! lol

Thats probably where ive gone wrong then, i will try more rear downforce.

Im on a PC BTW. :)

That's pcars1 but I'm very sure it must still apply

Crank up the downforce. This car has so much power that drag means nothing.
Watch your rake too.
You could also tighten the accel ramp and use the throttle for oversteer exits out of slow corners.

It certainly does when the boost is at 100%!

But its not easy keeping the rears in check @ 100% boost from tight corners, My rear toe in across most tracks is 0.3 to 0.6. I consider that to be a lot.

Only way to do it.

What Engine Braking are you using?
