SC10 - SCX60 Astro Setup Tips

[jmke]

Any specific AE SC10/X-Factory SCX-60 suggestions for a good astroturf setup?

I'm coming from a setup which worked well on a loosy clay, 1/8 track with large swoops and few sharp corners.
That same setup on a tight astro track is far from ideal. ( movie of the track http://www.youtube.com/watch?v=i1mRhUplyzw )

So far I've figured out the following (with help of friends and rc enthusiasts)

- Stiffer springs
- heavier shock oil
- lower ride height

what more? Bit of a newcomer

any tips for anti-squat; camber; toe in/out that would help a 2WD SCT to turn better at low speed; at high speed truck goes where I want it to; at low speeds heavy understeer (partly due to sucky tyres... schumacher SC tyres ordered)

thanks for any and all replies
