i think most people here are forgetting what is creating the power we use. each motor spools up different and has different torque values at lower RPM. a motor requires different gearing, perhaps to tame it low down, or to make it spool up harder and faster, dependant of the grip levels of the track.
while SP racer informed us of the front roll center, his is a great track indeed, and grip levels are quite high. one thing for certain, clutch setup is also critical. high spring tension creates a later engaging clutch, more into the power band of a motors low end power, set this too high, and it will make the car very hard to get rear traction. i used a black spring, red clutch shoe, and no weights in the throw out shoes, 0.4 spring tension, 0.5 clutch gap. this was a good clutch setup for a lower traction track, made the use of throttle control very controllable. very consistent power delivery, provided your not just grabbing that throttle, then no clutch setup will be of assistance there.
the clutch is a wonderfull thing, use it to your advantage
a basic setup for the car, would be

Front....
70K front diff oil
inner hole for outer steering link on hubs
Aqua front spring, 50W oil std holes, or you can open them up to 1.2 or more with 60W oil
outer bottom arm shock position, 2nd inner hole on tower
inner middle , or bottom lower speed shot roll center
dependant of amount of steering, 197 track width 1mm toe out -2 camber

rear...
same shock setup as front. std rear spring(silver) or mugen or serpent 1.6 spring (more progressive)
outer lower shock mount, 1st inner hole shock mount
middle inner top camber link, 2mm spacer on hub
2mm shorter wheel base, 200mm track width -2.5 deg camber
2mm toe in each wheel. soft rear swaybar
10 - 15k diff oil
the car loves 40-42 shore front tires 40 rears or 38 dependant of grip.
this is a general setup, and may require some different adjustments dependant of track conditions. but a good starting point.
