Patrick,
I have had four local racers use the Hanulec/Fairtrace set up (snowbirds regardless of chassis type) and had success right off the bat. In all fairness to Gee and the Klingforths of course.
The two adjustments I make for my track is a softer rear bar (1.0) and currently swapping dampeners and in asymmetrical for the rear only. Some reports from the iic stated the track got to bumpy for this so maybe it only works on smoother tracks?
