Well,
I ended up ordering the following stuff :
- ali hingepin brace
- hex screw set (steel, perhaps later Ti)
- 10° castor blocks
- full set of springs
- CF upper chassis
- AE carbide diff balls
- Ali wheel hexes
I hope this will do to have a competitive package for the upcoming season.
I will be running Orion 10x2 or 12x2 and GP3700's, but I hope to make the switch to brushless soon (was thinking about the LRP Vector 3*).
