Jaroslav is running a steel chassis with optional short arms, short upper link arms, and an optional front 1.2mm anti-roll bar.
He also fitted a stiffer rear linear spring (C=2.9) for more on-power steering.
The shocks have PSS inserts and pistons mounts, with 350 cSt oil, to sharpen up the car for this fast asphalt track.
Jaroslav was on pace from the start of the event, only fine tuning his setup with small toe- and camber changes.
