You really have created some interest very quickly with this thread.
There are lots of good points that have been pointed out here that have obviously worked for some. Some very interesting ones too.
I'm also very interested to see that some have found turning to softer sus' springs helped. Yet others have noted the opposite. Although only marginal help when going stiffer, if at all.
The point touched upon earlier concerning stiffer springs makes the car reacts quicker I think has some merit in that it allows the same thing to happen (grip roll) but quicker.
That same reason only opposite could be true why others have noted that going softer on springing helps.............. traction roll still occurs, but slower, maybe more controllable.
Because it takes longer to get to the point the car actually flips, this could be the reason people feel it helps.
One thing is for sure.
We are basically talking leverage here. If there is applied enough cornering force against the amount of grip (friction) generated by the outside tires (the fulcrum) the car will flip!
In this respect it does not matter if you use softer or harder springing.
What can help to prevent this occuring?
Lowering the centre of gravity will help. But if the amount of grip generated at the wheel is suficient and the cornering force is enough to overcome this, you will still grip roll !
Lowering the roll centre will also help, but as above, if there is enough grip being generated, the car will still G roll ! Stiffer roll bars, suspension limiters and changing akerman. (Sorry about the spelling guys
While all the things mentioned will help to find out how much grip is being generated at the tire, ultimately what we may need to do is actually take grip away from the outside tire. The car needs to overcome the friction felt at the fulcrum point to stop the car from flipping.......traction rolling.
Don't get me wrong. The remedies mentioned may well succeed in getting rid of traction rolling by overcoming the amount of grip at the outside wheel. Where the amount of grip is already close to being met and exceeded at max cornering force.
Tires ! ......Tires, Tires ,Tires. Loosing grip, taking away the grip generated here will get rid of traction roll.
Harder shore,....speaks for itself.
Less width,...... I don't just mean making a 26mm wheel into a 22mm wheel. But cutting the foam at the edges more. Rather then just round them off slightly, takeaway the ability for the tire to roll over by chamfering the foam aggressively inward and also create a smaller contact patch with the track.
Smaller diameter tires....speaks again for itself.
Use of the stiffest tire rims available. GQ's I think are the stiffest. (
Stiffening up the outer side of the foam on the tire. Not just the tire wall but also the part radiused when cutting the tire for size. By using some kind of glue maybe
Ultimately, grooving the tires. Making grooves around the tires circumference. One two or even three grooves here should be enough to take away enough grip at even the most highest of high traction tracks.
Sorry for the long post guys. I hope you found this helpful aswell as interesting.
This is a subject I find interesting because this does not happen in full scale motorsports.
So no real help there from my experience. It's kind of unique to this game.
But the rules for getting rid of roll still apply. Or making the grip roll more controlable by letting the car roll more.......
very interesting idea.
So in short.
Try all of these fixes people have put here. They all must work as they would not have put them down here if they hadn't. Some more then others but all have their limits. And if this limit is exceeded by the tires grip, and the car still flips. You must remove grip from the car and the tire as outlined above.
I hope I have not board you all with all this.....nothing else interesting to do at work.
Good posts everyone on the subject. Good to see people's thoughts and experiences coming together to help people.
Have fun all.
