I would start with stock setup which is good starting point. I race with some minor changes:
1. Less front toe out (around 1.5)
2. Springs (I use SMJ - 2.8 or 3.0 linear rear, 2.7-3 progressive front
3. One step harder front antirollbar
4. Soft (ball) central stiffener
5. Top Deck from WS
If you use alu deck I would recommend to use thinner top deck (Vigor 1.6)
Diff oil 6k up. Lately I use 8k some use 10k
Dampers oil 450-500
Important:
1. Mill/sand topdeck near spur gear as the clearance is too small. While driving it will spur rubs against topdeck (I had this in 419X, WS and XR as well)
2. Use third bearing inside spur gear (pulleys). You have to buy this separately. It will save you pain with sloppy spur and shaft. In the end pulleys would have to be replaced as they wobble. It cannot be shimmed as the shims press against bearings making them too tight.
Those are IMHO two obvious flaws in this model.
