Hello,

I'm looking for a setup that could limit the huge understeering of the Focus RS.
I already tried a few things :

Lower front pressure
Rise the caster
Stiffen the rear ARB

Maybe playing with the rear spring...
Any ideas are welcome :)

Thanks,
Sguby

All FWD cars are busted, forget it. I've driven focus st and rs, and some more fwd cars on a track, it's not even close to what PCARS "simulates".

Stick with RWD cars, they're pretty fine.

Thanks, that might also explain why even if tweaked the FFB seems so loosy...

Just make sure the tyre pressure is making the tyre fully contact the platform. Check the temp readings. Too little can give you almost not traction. Then

Okay now try these:

*differential *

- decrease acceleration lock
Decrease deaccelaration lock (don't decrease too much, it might cause unsteady breaking)

If still understeer

*camber*
More negative front
More negative back

*spring rate*
soften the front sprint rate and harden the rear sprint rate

*slow bump rebound *
Soften the front sprint and harden the rear springs*

Check do these little by little, when you get there lower the ride height just a Lil before bottoming out.

Thanks, I was thinking of that for the spring rate but I'm not familiar with all the suspensions settings yet :)
I'll give a try tonight when back home :)

I arrived at this page while looking for an answer as to why I was having trouble driving the Focus RS round Sonoma. I was basically going off at every corner. I know FWD cars have a tendency to understeer, as I have driven them most of my adult life, including performance cars like the Audi TT, but this was ridiculous. If a real car I had bought drove like that it would be straight back to the dealer. Most of the cars I have driven in Project Cars have been fine except maybe the Escort in a historic race which also understeered a lot, but I think that is RWD?

I think a fix is needed.

I think this is fixable and I hope it will be. I had the exact same issue with the Clio before 1.3 and after 1.3 it was fine. I ran the exact same tune before and after the patch. It doesn't just understeer, the wheels don't even seem to move because you can get more steering out of it by turning more, if you had understeer it wouldn't matter much if you turned the wheel more.

Just as you, I've driven plenty of FWD cars and if they behaved like that they'd be in the scrapper by now.

I tried re-calibrating my Thrustmaster TX wheel using about 750 degrees instead of 900, making it roughly equal to my own car, and it made the Focus RS easier to turn and I was able to complete the race at Sonoma without leaving the track. I believe some cars in the game such as Formula A automatically adjust the steering ratio to make it tighter, but road cars use the full movement of the wheel. It may be something that you have to get used to after playing games like Forza which seem to have much tighter steering.

205985I'll stick a tune up. You promise me you'll not blow the engine as shes tuned to stand on her nose!
100% Brake pressure, 58% Brake bias, 12.6:1 recommended steering ratio (my speed sensitivity is 45)
Theres no minus sign on the toe so match the plus figues on screen. 65% Accel and 65% Decel, 100Nm Preload. 30L fuel. 3.38first gear. If in doubt, flat out! She luvs a bit o left foot braking, but a pump on the gas is usually all she needs!
