I think what is trying to be said is with stiffer springs the car reacts faster and the car traction rolls violently. When you soften the car it make the chassis react more slowly and will help stop traction rolls.

We are in a nitro onroad forum.

I have found that stiffer front springs usually make a traction rolling problem worse. I have tried stiff, stiffer, super stiff, etc. I have never tried going softer, but stiffer has never been that effective at eliminating traction rolling. Maybe I will try going softer, but the tire size has been very effective. (Something they do in carpet)

There are things to try, but I have found harder front tires with a smaller diameter (less sidewall) is the best method to get rid of traction rolling issues. If you lose too much steering, then try a softer shore tire at the smaller diameter.

I also agree that going stiff to super stiff is not always the ways to go, it can be hard to know what exactly to do in all conditions as the setups on the car are not always the same so the solution is not always the same.

One thing that nobody has mentioned yet that works is if you are not at max. width yet, you can try widening the car, this works well sometimes. An example would be in 1/8th sometimes to get steering at one track you might be narrow in the front. By going to a wider width front end its harder for it to roll and also can produce a more stable car also.

go with lower shock oil and softer spring, i even tried to use EP springs for front with great result.

wider front track width also helps a lot

That's right.

This is what I had experience with MTX3. I use harder springs before and it still traction roll on some corners. Until someday ......... I decided to use softer spring at front ( 1.6 purple mugen ), 200mm width, shave front tires to 63mm diameter, and VOILA !!! Surprisingly the traction roll become so much less frequent than before.

Default ride height setup

1) 1/10 GP front/rear general ride height setup in 5 minutes race

2) 1/10 GP front/rear general ride height setup in 30~45 minutes race.

3) to avoid traction roll, how can ride height change?

I've been told you can also reduce traction roll by limiting the uptravel of the suspension (droop).
