good man Pete  Smiley

i think the variety of aero combinations will be interesting in the race tonight. I dont think i've struggled as much to get a setup right as i have at this track. Every tweak to improve on one part of the track felt like a compromise on another  Undecided My wing settings have gone up and down like a yo-yo  laugh

It is a cracking track though for these cars  Cool

Yes, very hard to understand the setting up path here also. This track is known for that too, yes ?

What is the ideal process to setup a car, and could aliens give inputs to this ? Here I try to go this path :

1. Rough gearbox length, rough aero
2. Geometry (asap cause it modifies everything else)
3. Tyres pressures (same)
4. Rough dampers/suspension
5. Drive train
6. Brakes/Engine RPM
7. Fine tune gearbox length/gears
8. Fine tune aero
9. Fine tune dampers/suspension.
10. Try hard. Cheesy

In case of BRM this goes more like this...
1. set full aero
2. realize theres no any traction
3. set low aero
4. realize that damn thing still not going fast and traction is totally zero now
5. go back full aero and enjoy race 'till you hit the wall or/and frustration...  Grin

hey, you've stolen my Brabham setup  laugh

My qually setup is very different from my race setup here. What works fine over a lap or two was hopeless when brimmed up. I'm still not overly happy with my race setup but it'll have to do. I went for consistency rather than outright pace as i think once the tyres go off, these cars will be a proper handful on low wing.

Hello and welcome to you Christian ! Cool

Pleased to see one more classic car enthusiast ! I'm french also by the way.

I just realised I hadn't put any more laps in this event though.  Embarrassed

Ah, cool , je me sens moins seul  Cheesy

Salut, Christian. Welcome!

I started with a soft suspension setup, then I move to stiffen and it seems better. Car is quite no-friendly in every case. About aero the Ferrari has a lot of downforce so I'm at minimum wings.

1. Tyre pressures - they won't be right at the end but you need them nearly right for the rest to actually work.

2. rough gearing (this is more like 1.5 as it's generally done while getting the tires right - you're only trying to get the car to hit nearly max revs in 5th at the fastest part of the track at this stage).

3. Aero + Geometry + springs/dampers. These 3 directly affect one another. More aero requires stiffer springs, stiffer springs require more damping, stiffer springs change ride height which changes nearly all geometry....
You'll have to experiment in stages at this point to balance your changes out as you work, so it can take several runs for it to start improving.

4. Diff settings + front/rear ride heiight - these are to suit you and the setup you created, in the 75's I'm finding them critical in controlling the car behaviour at lower speeds when the aero stops working. Ride height can do a good job of helping the car to turn to suit you, the diff can limit or encourage over-rotation for you (when done right).

5. Have another fiddle with aero to see if you can make the car drive better/lap faster.

6. Serious gearing overhaul. Personally I run 1st long enough to be used in the slowest corners on tracks where that is useful (i.e. here). The car should be geared to avoid having to change under power in a corner wherever possible and also never drop below the useful power band (about 7.5/8000 RPM in the DFV stuff) unless you are in 1st.

7. finalise tire pressures.

8. Calculate fuel load for 45 mins + 1.5 laps - apply to setup and save for race. Test to see if the car remains drivable with the extra fuel - often improving the fully loaded car still results in a better car late in the race.

9. Start pretty much from scratch for a qualifying setup because the softs behave so differently  Grin

10. Somehow launch a car with 1st geared to 100Mph or more, then try not to die during the rest of the race.

This race was probably the closest experience to races "old style", when pilots also had to fight with car problems.

I realized that I had problems with the gear stick (I mean the physical one) as soon as I joined in server. I was hoping that the problem was reduced by using the stick, but unfortunately it was not so. Some laps were really terrible.
I had some troubles with the gear stick in the past but I thought I had solved them by removing the "cap". Unfortunately, tonight the problem was big and almost unplayable. I was near to quit.

The race was interesting and I started well, going side by side with FMG during first corners. Then I had a close fight with Mark, Louis and my gear-stick. I finished 3rd.

That reminded me when I had gearbox problems with my motorbike and gears went often off/out. A bordel.  Grin

Congratulations to Tim, Mark and also to Louis (a little unlucky).

I will come back on the race later but I would like to shout 2 sorry to Laurent and Bob :

@ Laurent : We both were very cautious at that end of straightline braking point, I did brake quite early too noticing you had overtaken me in the straightline, but there was plenty of room in front of me outlane so I went in, then I saw you lowering your speed throught the 1 st apex and I surprisingly was passing you in my finish of 1st corner, but as to me those 2 left corners are actually 1 double left I went a tad on my left to catch the 2nd apex, still in a out lane, but unfortunately we had very different trajectories there and my rear left wheel caught your front right  Embarrassed I'm really sorry but I couldn't even see any part of your car right at this time, you were in my dead view, I only knew you were somewhere in my rear left, but couldn't imagine we were so close because I had spotted you far in the inside so far. A shame then for all the fellows who were caught in the mayhem it caused.

@ Bob : we got several critical moments ! Cheesy You didn't spot me at your rear left once, then when we were side by side at turn 1 you pressed me outside, we contacted, but miraculously kept cars on track. Then that 3-4 cars close fight with Syd in front was outstanding and I noticed that you guys were braking early at Ferradura but the lap after, even if I had noticed it and wanted to be careful I've been surprised again, I was afraid to contact you so did a small emergency left move which led to me getting the kerb, losing control and eventually tapping you. :/

I will do a drive-through @lap 1 next race.  Roll Eyes

A pretty woeful race for me. I managed to avoid the first lap chaos, but I had horrendous understeer everywhere, that went into snap oversteer as soon as I managed to get any power down. So there was no way I could defend any of the places I'd made up. And then on the last lap, I washed out wide at the fastest curve just after the start line and so ended up a well deserved last. Not one to remember... Any suggestions where to look for tips on setup?
