The GP4 Car Setup and Handling Thread

I'm having difficulty with wet weather setup for keyboard...Does anyone have some good pointers?

Cheers

I put them in GPSSaves just to be sure.

The 17 track setups are for the original game, am I wasting my time trying them out for the 1991 mod?

Yes, this is how I drive all the time, not only does it lock your tyres braking 100% all the time into the corners, but it also has a hugely detrimental effect on cornering grip. Anyway, I believe the issue is a fundamental GP4 physics issue and nothing to do with the way I'm driving; I can set the brake balance as far back as it will go and it will still lock the front tyres.

Fortunately, I have downloaded all the 2010 cars,and I am using Cyber-Racer's 2010 Super-soft Physics. I'm still using the default tracks, with the exception of Melbourne,Sepang,Imola,China,Monaco,Nurburgring,Silverstone,Hungary,Germany,Monza, but even these tracks vary from 2005-2010 layouts. To be fair,I have made a slight modification to Cyber-racer's physics file (if you read this Cyber-racer,please don't get upset,and can I get your acknowledgement?), because the braking force was not powerful enough. However,apart from that, and I am using keyboard, personally,I prefer a twitchy car,but now it's extremely stable. Try downloading Cyber-racer's 2010 Physics,and get yourself a 2010 performance file, and set yourself within 500 performance points of Fernando Alonso, who has the highest,because,for some reason,human input always makes the cars go faster. I am lapping in some crazy times. Take this: on the default GP4, I lapped Melbourne in 1 min 27.9 secs. With the mods, I lapped in a 1 min 16.7 secs. In Monaco I lapped in 1.19 but with the mods,I have set a few 1.06s. But it depends. I only installed the latest GP4 Patch (ver 9.6) and that,apart from my mentioned modifications,is all I have changed.

Hi AJ05.

Using only the 2010 physics is not enough...
You should also use the 2010 TORQUES and "Gitane's 2010 Perfomances".
If you use the original GP4 torques you will drive faster lap times...


Here are some issues about the braking force:

I develop physics using 4-5 original GP4 tracks - with original magic data.
Each track is used to develop and adjust different parameters of physics, depending on its characteristics.
The released versions of physics (with soft and super-soft tyres) give in ALL these tracks realistic lap times, realistic drive through speeds in corners of different radius and realistic braking points.
These realistic braking points are taken from real pole laps, but in GP4, only AI cars manage to brake accurately after starting braking at these same points.
Human players have usually to brake a bit earlier, to avoid locking the wheels...

This may make you think that you should have a bit more braking force to brake exactly at the points you see the real F1 cars brake on TV.
If I were to use more braking force I would have to use less downforce and less tyre grip to maintain the same overall car performance and keep the same lap times. But such a choice would give less realistic drive through speed in corners and wouldn't fit to the 2010 cars.

And after experimenting with making physics for various F1 seasons and various non-F1 mods, I can say that GP4's mathematic function of physics does not fit perfectly to the 2010 cars, so making the 2010 physics contains some compromises...


I'll explain now the "crazy times" you lap:

Raising the braking force (I have absolutely no problem with that - ) is a change that gives faster lap times.
Using "super-soft" physics in tracks where you should use the "soft" version gives also faster lap times.
You could use this info:
Bridgestone tyre compounds for the 2010 season: (available @ [www.formula1.com] )
Bahrain (Sakhir) - super soft, medium
Australia (Melbourne) - soft, hard
Malaysia (Sepang) - soft, hard
China (Shanghai) - soft, hard
Spain (Barcelona) - soft, hard
Monaco (Monte Carlo) - super soft, medium
Turkey (Istanbul) - soft, hard
Canada (Montreal) - super soft, medium
Europe (Valencia) - super soft, medium
Great Britain (Silverstone) - soft, hard
Germany (Hockenheim) - super soft, hard
Hungary (Hungaroring) - super soft, medium
Belgium (Spa-Francorchamps) - soft, hard
Italy (Monza) - soft, hard
Singapore (Singapore) - super soft, medium
Japan (Suzuka) - soft, hard
Korea (Yeongam) - soft, hard
Brazil (Interlagos) - super soft, medium
Abu Dhabi (Yas Marina Circuit) - super soft, medium

But the main reason for lapping faster lap times is that the grip in the modified tracks you drive, is much higher than in original GP4 tracks.
These higher and unrealistic grip values are also to blame for not driving a twichy car - as you would like.
Higher grip values prevent the wheels from sliding and the car seems to be stable like a train on its rails.
2010 physics make the car twitchy, less twitchy than the 2009 physics but still twitchy.
If you adjust top speed and lap times following my directions in the "how to install" - doc file of the reality pack, you will edit the track grip and will get a more twitchy car.

Hi there.
Fair point Cyber-Racer: When I install the magic data from the original GP4 tracks, despite the different WADs and DATs, the lap times fall within 2 seconds of this year's fastest times. But I can't always get what I wish for, so I'm content with what I have; and thank you. By the way, about my still crazy lap times, I think I should mention this is F1, and it's meant to be the fastest racing category in the world,so hopefully one day, they'll achieve the same lap times I do

Does anyone have car setups for the tracks on the 2001 season that came with the game? I'm on Imola right now and I have the distinction of being the slowest car on track.

Any help would be appreciated?

A pity my old HDD doesn't work anymore. I had an archive of all my setups from my league racing time there (all on original tracks and physics of course).
But what you can do is go to www.hotlaps.de. There's a GP4-section where you can download the replays of the driven laps at Imola. After downloading use SDI's HOFxLap to open the replay and extract the setup. You can then load it in the game. Make sure though you raise the ride height significantly as the blank in the hotlap-setup is set to last for one lap only to maximise grip for that one lap.

kind regards
chris

I will give that a try.

Any other suggestions?

Any setups for 1991?

I got a 2003 car setups pack - actually most of them are dated in 2002.
Setups work well with original game's physics and tracks.
As I don't remember where I found it, I just uploaded here:
[www.gamefront.com]

I hope they are what you look for...

Hello guys,
I have some problems in the Hungaroring track with the setup car, i lose like 1.1 - 1.3 sec in the second sector. Can you help with a setup car for Hungaroring track?

Are you using keyboard or wheel?

I'm digging this thread up to ask a question about Monaco.
I'm currently doing a "stock" season, meaning default physics / performances, and I'm quite puzzled:
In the previous race I had no real issue customizing the setup, but here in Monaco I cannot find a better setup than the stock one. I'm able to do low 1.16s (around 1.16.2-1.16.3) quite regularly, and every time i tried to alter the setup, the car is slower. I've been surprised in particular by the effects of wings: my first step, after doing a good bunch of laps to warm up, has been to add more wings (20f/18r). Weirdly, the car felt far heavy, I was thinking that with more wings handling in corners would be better, but it was the opposite.

I tried with a balanced setup (18/18), same behavior. (strangely i felt that with less wing at the back the car wasn't turning as sharply)

Then i tried to change the suspension settings, trying to find a way to have a smoother drive in Casino, but again, whatever I did it felt worse. Even lowering the car with a reasonable amount of packers to prevent plank wear had no real effect. The only thing that did work as expected was totally remove the fast dampers to be able to smooth the ride in the chicane after the tunnel. And that doesn't help with lap times.

I'm starting to wonder if the default setup of the car, which is the same for all tracks, might just be the one set for Monaco by the developers.
So to all drivers here: what do you actually do on your setup to drive at Monaco ? (note: i'm not looking for uber fast qualification setup tips, more full length race stable one. )

Hello,

I play in rookie mode and I have the mods from 1975 to 2021

I keep the game's set up

I don t understand why in some years/mod, the car behaves perfectly and in others the car spins at every turn !!
