My setup is pretty much along the same line as sly and steve.
8K diff oil
Front shocks,4 hole pistons,blue losi springs,32.5 fastrax oil
Rear shocks,4 hole pistons,yellow losi springs,27.5 fastrax oil
I have 20g weight in front of the servo,80g weight under the lipo's,although i run my car in saddle formation so the under lipo weight may not be right for the car in stick layout.
Cant fault the car at the minute,its getting better with each metting
