Loads of general info and proven setups here.

Is a good safe starting setup, if you find the car rolls too much in the corners I'd try increasing the front oil to 600cst and maybe even increasing the front spring to Xgear Orange.
If you let me know how you get on I'll try to help you fine tune.
One thing I'd say is forget my motor and gearing selection ..... that is a quick setup. I'd start with something like a 10.5 on gearing 29/78.
Where will you be racing?
Hope that helps.
