If you feel the rear is stepping out on you too much, soften the rear damping.
By softening the rear, it will allow the rear tire to get a bit more traction.
This will help reduce the over steer feeling that you may have.
Another thing to check is tire pressure and alignment.
If the tire pressure is low, or the rear toe is pointing out, you may have the described feeling also.
Have a look can check things over.
The suspension works together with the tires and alignment, so every part do play a role in how the car behave.
The adjustment in the suspension just allow you to have control over what you like, but you have to make sure everything else is working together also.
Any questions, just let us know.
That is why we are here.
