Front inner turnbuckle position

- Higher, less turn in but more mid and exit grip, more chassis roll (lower roll centre)

- Lower, more turn in but less mid and exit grip, less chassis roll (higher roll centre)

A lower position will give more aggressive turn in, higher a smoother turn in, more grip at corner exit

Same results but opposite if changing at the hub end, higher turnbuckle at hub same as lower at inner position.

Im sure someone will correct me if im not quite right on this.

Hope this helps - SAM D

Longer link = more traction and less stability.
Shorter link = less traction and greater stability.

Lower mounting positions will provide more traction.
Higher position will give less traction.
Yes?

Samd,
If I understand you correct, if I choose the lower position of arms, the car will be more responsive in the start of corner?
