Green Speed,
Thanks for your kinds words. I think it's a good thing to have a thread like this so I can help everyone out.
Chassis tweak:
I always set my chassis on two support blocks and then I tight up the topdeck. After a crash I always untight the screws and do this. Then I first check the downstops without shocks. After I check the length of the shocks I put on the shocks and check the downstops again. I always measure the distance from the spring collar to the top so all left and right are equal. Sometimes I match some springs and try to find two with the same length but the differents is minimum anyway.
I always use 90% lock so the steering block have 2/3mm distance till the caster blocks, must have little play.
A softer spring helps to avoid tyre overheating as well as run thicker oil. Like Worlds in Thailand we ran HB blue spring(14Lb) with 700 oil.
