droop
Alex,
Yes, I ALWAYS adjust my droop based on my ride height. If I make a tire change and then have to readjust ride height due to the shorter or taller tire I go back and check the droop. If you don't do this and don't have enough droop in the rear you can end up with a tire that loses contact with the track surface and then your in trouble. Also 4mm front droop is a bit much. I rarely go more than 2mm droop in front. Something else I recently tried that made the car smoother on initial trun-in and in mid turn was place a 1mm shim under each ball link on the front uprights where the steering arms snap onto. I think this changes the ackerman effect and gives the car a smoother feel through the turns. It worked for me so I'm sticking with it. Hopes this helps.
Regards,
Daniel
