hy boy´s
in the rear droop ca.1,5mm - moore rear droop makes the car more turn in - but little onpower steering
in the rear - minimal droop make the care easy turn in - and more onpower steering
front droop ca.1mm - moore droop make the car less onpower steering - more weight in the rear...
i drive the kingpins in the front - and there are the shims under the steering arm for the droop - more shims make less droop - less shims make more droop
i can not say - witch droop by low gripp - and witch droop by much gripp - you must take the balance of the car this is very important
hope this helps
