How to avoid 'stoppies'?

[samygrandao]

I'm having problem with an abarth 500 at 550pp tuning: i can't stop it to make stoppies. i tryied balast, change suspension setup, and makes no difference. what should i do?
I'm not a very good at tuning, but i tryied stuff that make some sense.

Try increasing anti roll bars and natural frequency. They reduce body roll so should help.

And with all the above, try to also not use race tyres.

It worked. Thx, man.
What is the principle behind of altering nat frequency?

I wasn't. They are ss tyres.

It stiffens your springs, which will make them, and thus the car more resistant to body roll.
Basically, you need more force to push them down, so when you accelerate, the rear is fighting more the force that pushes it down.

Another good tip is to also make sure your dampers compression on the rear are stiff, to also add more resistance to this force, but it will make the rear over bumps a bit of a big pain.

Regarding the tyres, the grippier they are, the stronger the wheelie is, aha.

Thx for the explanation. I thought changing the damping ratio would do that.
My 500 is now almost competitive.
