My job is keeping me very busy, but I've not forgot this thread and the people I help.

TO DO LIST:
-Add sway bar stiffness calculator to final version spreadsheet;
-Glossary!
-More tips, have some about roll bars.

One very important part of the whole setup dynamics is acknowledging that all buggies can be fast. Doesn't matter suspension geometry or chassis width/flex/cut outs. These can be changed to alter feel or tune to a certain driving/track characteristic.
I'm reading again that gentleman are having issues with on power traction on the RC8B3 and other new gen buggies. Some tips:
Assuming a mechanically sound buggy and running level rear arms with ground, how are the rear tires wearing? More than the front tires? On the inside, outside or center of the thread? Typically having on power oversteer is a symptom of rear wheel rolling too much and can be cured by lowering the inner camber link position on the rear shock tower (effectively decreasing rear roll couple); running a thicker rear anti roll bar and/or stiffer spring in the rear. Anti squat works if the buggy squats too much on acceleration and causes the wheels to gain camber, the other adjustments work if you have to wait for it to finish the corner before accelerating. Running a less aggressive front end works too but it's your call if you want to mess with the front end.

I also saw that the stock rear camber link length is long, coupled with lot's of roll it can cause the rear tires to loose camber and then the buggy rides on the sidewall. A short rear camber link cures that issue but beware the buggy might roll more now that has more available grip!
