I would like to share my setup for "dirt tracks" on an European Track (2001 at St Gaudens).

I have use "Saddle" batteries because "Shorty" batteries make the car too light for dirt. The feeling was better with "Saddles" and Lap time more consistent (more traction).

The differences with the usual setup are:
- shocks locations (Inside arms in front and Outside arms in Rear)
- shock piston (4x1.3 in the Front to get more "pack" and 2x1.8 in the Rear to be softer)
- Antisquat - More than 3°...close of 4° to get more stability during braking and lateral grip.
