Hi
Its not as easy at that
Car set up is a very black art, even with a good driver in a good car on a circuit were the variables are limited, ie you have the same coners etc
It all depends were the US is, coner entry, apex, exit???
I guess on your Leon its corner entry
If you has US on entry you want a stiffer ARB (in most cases)
A stiffer bar will give less body roll, less weight transfer so it will ease the tyre load and should
help with entry US
Alot of people think if you have US you run a softer bar NOT TRUE in all cases
Coner exit US it normally caused by putting the power on and weight transfer and using the available grip in acceleration and cornering etc etc
I have a Leon Cupra and body roll is pretty large
You can
help US alot by turning into the corner softer, more progessive, dont apply to much power to early this will play with the weight and make the US worse
The tyre only has so much grip and it can be used in 4 ways mainly, cornering, breaking, cornering and breaking or acceleration, to make things easy if your tyre has 100kg of grip you can use all 100kg in acceleration, or braking, or cornering, or a mix ie 50kg on coner and 50 kg on breaking, its how you use the grip
ALWAYS steer with your outside hand, your inner hand should just steady the wheel, using your outer hand and PUSHING the wheel will
help you feeel whats happeneing, do not pull the wheel!
US is caused by the tyre reaching its grip limit, if you lessen the wheel angle, lessen weight transfer and drive smooth it helps alot
What I mean is it may bebetter to change driving style then change the ARB and see how you get on
Hope this helps
Marcus
