Red Bull X2010 Sebastian Vettel – shimmy/wobble

[DJ Poirier]

Using the Logitech Driving Force GT and when ever the car is going in a straight line, there is a very pronounced high speed wobble (quick left to right steering wheel motions) that is fatiguing at best, and at worst really frustrating . I’ve tried adjusting the toe and driving aids but, as yet, I’ve found nothing to mitigate this problem.

Has anyone experienced this?
Has anyone successfully fixed the problem?
How?

What is your car setup like?
Try lowering the camber (giving you more straight line stability), soften up the springs(giving you more grip), and change the toe to -0.15 in the front, and 0.15 in the rear.

Here is what I am currently running, which are the standard/default settings:
Camber Angle (-) 2.0/1.0
Toe Angle -0.50/0.50
Ride Height (mm) 0/0 (none adjustable)
Spring Rate (kgf/mm) 17.4/17.5
Dampers (Ext) 8/8
Dampers (Comp) 8/8
Anti-Roll 7/7

I tried your suggestions …
Decreased toe to -.25/+.25
Decreased camber to 1.0/1.0
Decreased spring rate to 12/12
… with no results.

After this I changed the wheel alignment settings
- tried completely neutral toe & camber (0) with softest settings for spring front and rear.
- Included a decrease in the damper compression & extension
- Decreased the anti-roll bar adjustment to 1 for both front and rear

Went to the Logitec wheel settings, hoping something there could be adjusted
- Steering type changed from Simulation/Professional
- Power assisted steering Off/On

Driving options menu
- Traction control
- Skid recovery force
- Active steering
- ASM
- ABS

All to no avail! Granted, all the above measurements need to done in unison because most of them work together to create a balanced car but, none of them seemed to make any difference what-so-ever.

What I still don’t know is how wide spread this problem is. Does everyone else just deal with it or is my situation unique?

I don't have this problem with a DS3.

It must be because of your wheel, turn the force feedback down or something.

Make sure the aids are off and that tire wear is on, and also that grip reduction is set to real. Make small adjustments, don't just drop the springs from 17 to 12. Here is my Suzuka setting, try it on Suzuka.
Downforce Maxed
trans: 265
suspension:

13.2 15.7
8 8
8 8
7 7
camber: 1.9 1.6
toe: -0.15 0.15

For other tracks, you may want more cornering ability and would want to raise the camber, then balance the hanlding with the aero, if there is oversteer or understeer. It is not the car or the wheel, as I am using the same car with the same wheel. Depending on the track/setup the car may have some wobble, but try not to fight the wheel, you don't need to grip the wheel tightly, just feel what the car is doing.

You cant eliminate it with a tune the wheel has just too much steering play.

Lower the ffb

I have this problem too and nothing anyone has suggested works. Even turning off the Force Feedback system for some reason doesn't work.

Don't connect the power suply! The USB cable is enough.

As far as I know it's an issue with all wheels unless they have some way to adjust the deadzone. I believe it plagues all Logitech wheels. Fanatec wheels have a way to adjust the deadzone which can eliminate it. It has nothing to do with the car. It is a problem with GT5 and the way it interacts with the wheel.

Thats what I have been doing lol. Though it's kinda hard to drive without the resistance.

dammit, I came on here hoping to find a fix for it. its not a high speed wobble either its just as bad at low speeds. it only really gets to me on the indy 500 track so i push the wheel aside and use the standard controller but that is a pain on other tracks like... ones with more than four corners. i know its not the car because it was happening to me last night on ferrari challenge as well (was testing a theory). the wheel without feedback is just pointless. i was going to pull my wheel apart last night to see if something was loose! good excuse to go and get another wheel methinks.

I have a DFGT, and my buddy has a G27. When I'm behind any of the two I don't have that problem, but when my buddy gets behind any of the two, it's like the wheel has a mind of it's owned.

............hmm, I think the whole thing is caused through the super high downforce. It's the same with the Formula cars.
Other cars, like the Veyron, Enzo, Viper, etc., are also very fast, but don't have that problem.

The only solution I know, is to turn off Force Feedback.

First of all its not logitechs wheel its the way the game is made. Use the wheel with any other game for example F1 2010 the wheel doesn't behave like in GT5. So how can you blame the wheel when other games dont have this problem. Its the makers of gt5 for giving us no option in wheel menu for rotation return to center tension and stuff like that. All they have for wheel settings is button assignment. You cant even turn of the ridiculous force feedback like other racing game. F1 2010 i can turn off force feedback completely and still have return to center tension
