I'm still on similar setups to my ones on Petit RC.
Changes;
2x1.6 front pistons and 500-550cst oils
2x1.7 rear pistons 400-450cst oils.
Front outer ball stud typically now runs 2mm under it.
Rear inner ball stud typically in the middle hole of the 3.
Changes are predominately based on the differences between the stock and HD chassis, I run the HD chassis that is in the ZX6.6 kit these days.
