What are you guys doing to get this car to behave? The default setup is dead slow at Brno and Spa. I've stiffened up the rear and shortened the gears and taken off a bit of rear wing, which helps, but it starts to get twitchy and still understeers mid-corner to exit. Do you get aggressive and try to throw the car into the corners? Any advice is appreciated!

Reduce Limited Slip Acceleration Lock to get rid of the corner exit understeer. Alternatively make the front springs softer (but this could be a downside with the many load changes in the chicanes).

I am looking for a decent Mclaren GT3 setup too, the car just is so unpredictable, oversteer on entry, mid corner understeer, its like you don't know whats coming

What assists are you using? GT3 cars have ABS and TC for a reason.

The 12C GT3 already has the front springs on full soft. I totally forgot about the assists as I run with them off all the time! Thanks for the info!

Could it be the front springs are TOO soft and riding on bump rubbers?

Honestly I think it's a case of overdriving the car. Brno is very prone to that because of all those slightly outside cambered corners.

Nonsense; who ever overdrives a race car? :)

if its over steer for the entry try increasing the deceleration on the differential, this will slow the car down more to keep it stable when off the throttle so try braking a little later but for sweeping bends you want momentum so brake earlier for the sweepers and later for the hairpins. when understeering mid turn soften the front roll bar and stiffen the rear, but if its an issue when on the power and throttle controlling mid turn then increase the acceleration on the differential and increase the traction control slip so it allows more wheelspin before aids help.

I race with 0 assists on. Is there assists on the car beyond the game settings as in the setup? not noticed anything

The 12C is a car that tempts you to over-drive it. I am doing 2:01's at Brno and you can't do that over-driving the car. My style is to brake a bit early and put the car in a position to get on the throttle as early as possible mid apex. There are a lot of 90 deg corners at Brno. Those 2 secs I'm looking for have to be in the setup.

I agree, i dont think there is much wrong with the 12c. IMO its the best handling gt3 car, a good tune would just add more to it but i favored the Porsche because i like the challenge it offers when tuning because of its understeer on the power. but i was able make something out of it on Oulton park tuning for a series and i think its the best gt3 in general for most tracks but top speed ones.

I meant, if you want to replicate RL you should set the assists to "Real". All GT3 cars will then have TC and ABS, just like IRL.

I'm not sure of it. Yes it is "easy" to drive and boosts your confidence but once you know it and try to push the car the right way, you can't deny that the 4C tends to understeer on mid/exit corner.
I try to get under 2'18 in quali at Spa with it. I'm close but as I don't know how to setup a car, I focus on my driving and I'm struggling with understeer. Particulary at Eau Rouge and T11.
I tried to move some sliders (aero, antiroll bar, tyre pressure) It's better but not perfect :(

I already answered this on the first page:


Reduce Limited Slip Acceleration Lock to get rid of the corner exit understeer...

Diff settings are very powerful.

Yeah, my #1 tip for project CARS tuning is to learn how the Differential works. It's a very dominant sub-system that determines a lot about the cornering behavior.

Mid-corner understeer can also be a consequence of too much REAR Toe-in so try pointing the rears a little more outwards in the setup.

I'm working on a tune for it right now which I'll be happy to share here if anyone wants it? Should be done by tomorrow.

Had the same problems with the McLaren. After a long night of testing, tweaking and swearing I finally found what I believe to be the right setup. I'm still not perfectly happy with it but once I got more time, I will look into it and improve handling on rather bumpy tracks. You will be able to floor it even before the apex in some tight turns like Barcelona Turn 10. Tried Watkins Glen with it and the car handles rather nervous and somewhat punishing if you sc*ew up :D Laguna Seca for example worked well for me after I got used to the complete new handling of the car.

202194

Additional settings which are not in the screen shot:

All driving aids are on.

Brake Pressure - 100%
Brake Balance - 55%
Brake Duct - 20% (on some tracks even less)
Traction Control Slip - 1%

Longitudinal Weight Bias - 52.3%

Steering Ratio - 20.4:1 (but that's personal preference)

Limited Slip Acceleration Lock - 80%
Limited Slip Deceleration Lock - 60%
Limited Slip Preload - 0
Radiator - 0% (because I play without damage for now so my engine can't blow up... you may want to adjust this to the lowest possible value without losing your engine)

Gearing - I just set the final drive as short as possible without touching the other gears. If however you hit top speed before the braking point of a straight, move your 6th gear's slider towards the right.

Fuel - (number of laps + 2) x fuel per lap
Qualifying Fuel - 10-20 l (depends on the track lenght)
Brake Mapping - 7
Restrictor - 34.4


Hope it helps you mate. I was kinda disappointed by the 12C when I took it out for the first test drive with stock settings, it handled terribly bad. Now I love the way how it powers around corners and chicanes.

Cheers

Can you give more information about the setup? Is the rear setup the same or is it stock?

Take a second look at the garage page, it's there.

@NegSpec13...please share your findings!

@Umer...yes indeed reducing the lock on the diff is the biggest factor in getting the car to respond in the turns esp the 90 deg corners at Brno. I also found that increasing the toe-out at the rear just 0.1 deg caused me to go 1 sec/lap slower at Brno.

@Spalato...thanks for sharing, I will test your settings and report.

Eric Rowland
14-05-2015, 09:53
I'm afraid your settings didn't work for me Spalato. Thank you for your info. There's just too much diff lock. I can get rid of some of the understeer, but I'm still 1 1/2 sec off where I'd like to be at Brno. A fast guy online the other night was in the 1:59's and my best is 2:01.1. I think this car needs to be driven aggressively and thrown into the corners a little bit. Also, maybe it's horses for courses. I will continue to pursue at a few other circuits. :beguiled:

I already answered this on the first page:

25% by default, I tried 18% and 0%, no big changes :( (but thx for the tip)
However, what I also tried and seems to help a bit in corner exits is to invert the weight balance from all to the rear to all to the front.

Eric Rowland

This car has a split personality or something. Maybe just 'or something'. I drove it at Watkins Glen GP last night online and it was quick with lots of grip and just a hint of understeer. Default setup, no assists, and a pleasure to drive. :cool:

I might be able to help. What exactly it's your problem and your current setup values?

Guys for slow corners:

anti roll bar or sway bar : balance front ARB for precise and grip / rear = stiffer less understeer
Slow bump rebound : soften the spring rate and specially mode to the front ; soft front n stiffer rear.
Sprint rate : soften the front more than the rear. Find a good balanced between responsiveness and grip.

For mid corners,

Downforce aero ; increase the front aero for less understeer.
Suspension spring rate ; as I said, to get rid of understeering you want to have softer front and stiffer rear. Find a good balance.

For overall steering feel ,

Differential lock ; acceleration lock: decrease as much as you can leaving traction for exit corners / for decelaration lock, decrease as much as you can while not harming breaking stability

Camber : increase for more open (or negative value) slightly in all four tires specially front.
Toe in for front tires maybe - 2 / leave rear within 0-2.

Caster : only increase slightly if you feel the car a little soft or lazy which also causes understeer .

Its not too different to the real car in the respect that it is hard to get a "spot on" setup, its one of the reasons why the MP4-12C GT3 wasnt a massive success in real life, alongside the reliability issues of course.

Here is a test setup a did quickly for nurburgrimg GP taking some the understeer off. I left a little wild on the rear 60% front bias, top acceleration from final drive.

Maybe when I get home I'll make some adjustments for brnuo probably settings it's suspension, bump stops, aero and etc.

I try to get under 2'18 in quali at Spa with it.

With more practice I managed to reach 2'17.3xx but I was stucked at this point. Fortunately or not, a bug deleted my save and I lost all I've done so far, setups included.
I took this occasion to setup my G27 correctly with Photonenbert's guide (forum.projectcarsgame.com/forumdisplay.php?121-PC-Technical-Help-amp-Support) and Jack Spade's tweaker files (http://forum.projectcarsgame.com/showthread.php?22938-Jack-Spade-FFB-Tweaker-Files).

I also watched Joni Varis's video (https://youtu.be/XD4qsGIbdGY) and took the indications he gave in the comments for the setup. Then, I changed the tyre pressure and sway bars and voila !


Aero to 1/2, ride height 65mm F & 75mm R, Brake pressure 87% and differential to 29/38/80 (top to bottom)

Yes, those are more ajustements than a real setup but it's enough for me, the car does not need more.

With that i've been able to get 1'16:7xx in an online quali session and the understeer is almost gone :

That's how I run it (with assists set to "real"), and the default setup for the McLaren 12C GT3 feels great to me. I think a lot of the subjective "feel" of the cars is attributed to driving style & controller config (deadzones, sensitivity, etc.), which is why some tunes/setups feel great to some drivers & awful to others. :)

I must say a big thanks for this post awesome work could be a little bit more tuning in the gearing department but apart from that awesome job keep up the good work now let's see you tame the new Bentley gt3 that is a beast of a car and will take a good time to get the handling right on this beast

Although I am on a pad and no wheel - this car is the most behaved handling car I've used so far. Pretty much default settings to boot but I did lower downforce F&R a smidge and lowered the tire pressure. Feels like its on rails to me, started my first GT3 career today with it and after reading not so hot reviews on it I was extremely pleased to personally find otherwise.

I think someone mentioned controller settings... maybe that's why its not on the mark for some. I can't wait to finish my season with it, the first race was at Laguna and A-F'd the rest of the pack by 20+ seconds.


...but the McLaren F1 is another animal entirely. Can't tune it for shite, feel like I've tried ev thing.

Thanks for this setup, strangely the maximum ride height at rear I can set (PC) is 70mm, so I set 70mm rear and 60mm front to retain the same rake. Not sure if I'm setting something wrong here though!

I believe that McL MP4-12C GT3 is bugged (on PS4), setting of rear ride height doesn't correspond with HUD telemetry which shows actual ride height. Also slow front bump/rebound, looks like effect of those settings is switched over.
