Stabilisers

The inside wheels lose traction compared to the outside wheels, because the whole car "rolls" outwards (along the longitudinal axis) and thus the outside wheels are loaded with more weight.
With the anti-roll bar you try to absorb this and get weight back onto the inside wheels of the corner.
Principles:
- Hard anti-roll bar - more direct steering behaviour
- too hard at the front understeer
- too hard at the rear - oversteer

Tyres

Camber
Tyres are a fundamental component on a race car. Camber controls the position of the tread in relation to the road, i.e. negative camber and the wheels are tilted inwards at the top. We leave the positive camber to the oval racers, in Formula 1 and touring car racing only negative camber values are set. The front wheels need more camber than the rear. When going straight, the grip of the front wheels is not so important, but in curves the car leans and with an optimal camber setting (almost) the entire tyre surface is on the road. The rear wheels would prefer 0 degrees of camber, as this gives them full contact with the road surface when accelerating (straight ahead). But the rear wheels also lean into the curve and thus negative camber is also set at the rear. The camber setting is adjusted via the tyre temperatures, i.e. too high a temperature on the inner side indicates too much negative camber.

Principles:
- more negative camber at the front than at the rear
- Never set positive camber, except in Nascar.
- consider the correlation of tyre temperatures (toe-in, pressure, differentials, etc.)
- the inner temperature should never be more than 10°C higher than the outer temperature

Toe-in
Toe-in is the static angle of the wheels (seen from above) to the car. Negative toe-in means that the wheels are positioned like an arrow in the direction of travel. A slightly negative toe-in on the front axle increases stability when driving straight (positive toe-in is again only suitable for oval tracks and Nascars), but affects braking behaviour. At the rear axle, you should only make small adjustments and here in a positive direction. Toe-in is a hotly debated topic and mainly depends on the driving style. However, a slightly negative toe-in at the front and a minimally positive one at the rear is a good starting setting.
Principles:
- slightly negative toe-in at the front minimally positive at the rear gives relative stability
- negative toe-in gives good straight-line braking

Pressure
The pressure in the tyre increases constantly as the tyre temperature rises. The hotter the track, the lower the pressure should be so that even after a few laps (hot tyre) the tread remains flat and does not bulge in the middle.

Principles (pressure):
- high track temperature low tyre pressure
- low tyre pressure better grip
- higher tyre pressure higher top speed

Important things to know about reading tyre temperatures
You have to drive a few laps evenly to get representative tyre temperatures.

Suspension settings Examples:

Increase (harden) front and rear springs:
The suspension becomes harder, the wheels may not be able to absorb all shocks, rolling resistance is increased.

Increase front springs:
Increases understeer, decreases oversteer, front rolling resistance is increased.

Increase rear springs:
Increases oversteer, decreases understeer, rear rolling resistance is increased.

Decrease front and rear springs (adjust softer):
The chassis becomes softer, the wheels can follow bumps better, increase traction, rolling resistance decreases.

Decrease front springs:
Increases oversteer, decreases understeer, front rolling resistance is reduced.

Decrease rear springs:
Increases understeer, decreases oversteer, front rolling resistance is reduced.

Handling problems and solutions: (always make changes one at a time and test)

Understeer in general:
- If the front tyre temperatures are optimal and the rear are not, increase the rear anti-roll bar.
- But if the front wheels are too hot, decrease the front anti-roll bar.
- If the front tyre pressures are optimal, decrease the rear pressure.
- Soften the front springs.

Understeer in fast corners:
- If front tyre temperatures are optimal, increase front downforce (increase splitter setting).
- If front tyres are too hot, reduce rear downforce (reduce rear wing).

Oversteer in general:
- If the rear tyre temperatures are optimal and the front ones are too low, increase the front anti-roll bar.
- If the rear tyre temperatures are too high, decrease the rear anti-roll bar.
- If the rear tyre pressures are optimal, decrease the front ones.
- Set rear springs softer.

Oversteer in fast corners:
- If rear tyre temperatures are optimal, increase rear downforce.
- If rear tyre temperatures are too hot, decrease downforce at the front.

Understeer at corner entry:
- Harden front shock absorbers.
- Reduce front toe-in.

Understeer on exit of corner:
- Rear shock absorbers harder.
- Front rebound dampers softer.

Oversteer on corner entry:
- Rear shock absorbers harder.
- Rear ground clearance too high compared to front.

Oversteer on exit of corner:
- Rear shock absorbers harder.
- Too much rear toe-in.

Instability when going straight:
- Tyre pressure in one or more wheels too low.
- Too little caster.
- Too much toe-in.

Too little speed on the straight:
- Too much downforce.
- Too much toe-in.
- Car is too high.
- Check gearbox tuning

Steering forces too high:
- Too much caster.
- Front tyre pressures too low.

Car bottoms out:
- Spring rates too low.
- Shock absorbers too soft.
- Too little suspension travel (suspension travel limiter).

All tyres too hot:
- Select harder tyre compound.

Front wheels too hot -> understeer:
- Increase front tyre pressure.

Rear wheels too hot -> oversteer:
- Rear tyre pressure too high.

Insides or outsides too warm:
- Adjust camber.

Centre is hotter than the outsides:
- Tyre pressure too high.

Hello everyone.

Just joined, after 4 or 5 years of not using GTR2 at all. Its nice to be back on the racetrack.

When looking both on and off line earlier, its become apparent that all my setups seem to no longer work. Mostly thats gearing (where the ratios max out to about 50mph in 6th gear).

I tried a few laps last night, for example at Sebring. I loaded up a Corvette setup from the online folder, but it was garbage (and topped out at about 100mph).

So, with that in mind, i wondered if anyone had, or could share, a setup pack for some (or indeed all) of the main cars? Doesnt necessarily need to be track specific!

Grateful for any input!

Thanks
Steve

Hello Steve.

It's nice that you've found your way back to us. It is probably due to various changes such as vehicles, tracks or even yourself that setups no longer fit. Fact is, it's a lot of work and unfortunately not everyone likes to share their setups, for whatever reason.

But it is clear that there are enough online setups and that some other setups from other tracks also fit quite well and the rest is up to you - for some of you here, this is certainly not an unknown aid that I am presenting here. I think we have all had it in our hands before or still do

Maybe it will help you or one or the other of our racers here in Kölsch.

By the way, we are looking forward to your setups in the online folder.

Greetings

Duck

Wie stell ick das Radio ein ?

Alter Ente, haste jetz das Komplette Setup-Guide Übersetzt oder wie

Nice

Also wenn ihm das nicht Hilft hat er kein Bock zu Fahren

Oft muss man auch nur das Getriebe neu Abstimmen. Die dämpfer und so passen eigentlich auch noch von den alten Setups.


PS:versuche siam schon im Forum zu überholen

Ich bin dieser Sprache zwar mächtig aber das selbst zu übersetzten?! Bitte wofür gibts Hilfen - geht doch viel schneller auch wenn es manchmal recht lustig ist was da so übersetzt wird

Hi
great Duck !!!

But where is the set up ????

Hahaha

Thanks to Admin for the organization of WEC
