Can't really help you with setups directly for Eden Park or the Belgium GP as I have never raced at either track.
One of the local lads round this way tried AE shocks on there S4, it wasn't to far off losi shocks, but like Bodypaint has said Losi shocks are the way to go if you can get / afford a set.
Pretty sure the front end was:
middle on tower
inside on wishbone
40wt oil
number 2 piston
blue spring
For the rear:
inside on tower
inside on wishbone
30 wt oil
losi blue piston
Am pretty sure it was a blue spring on the rear as this was similar to a losi pink spring, where as the AE silver spring (being softer than blue) is more like a yellow.
I never ran any washers under the ball stud on the front camber link.
On the rear - middle hole on hub carrier and 3 - 4 mm washers under inner ball stud
Short wheel base
2 degree anti squat
big rear wing
Hope that helps
