Not 100% happy with these but may be of use to others…
These are what I developed at the Carpet Thrashnal on the 15th November. They were good enough to qualify 5th in 13.5, and finish 5th and 2nd in the finals. There is definitely a lot more to come.
The initial setup is what I threw on the car before arrival. It has a few tweaks to the roll centres, shocks and bars compared to the kit setup. It proved to have a bit too much steering, so during the day I stiffened the oil, springs and bars, and raised the roll centres to get the final setup, which was well balanced but a bit edgy at the limit once the grip came up.
Unfortunately I ran out of parts before I could try any stiffer suspension or chassis settings! Will be trying the foam top-deck and 1.4mm bars at the next meeting – possibly more. These parts seem to be working well in other hands.
Sorry about the poor image quality – I don’t have full Acrobat so re-scan the sheets into the computer!

If you try these setups and have any feedback, please let me know!
