Factory Team adds a new tuning element for the 13mm shocks with new 3-hole pistons. 3-hole pistons change the valving to have softer initial damping and lower pack with three smaller holes.

This is traditionally used to make the car have more traction on lower grip, or to slow reaction on high traction surfaces.

The team found 3-hole setups to be beneficial on outdoor artificial grass surfaces, as Markus Kaerup used them to win the 2022 4WD Modified European Championships with his 13mm shock-equipped RC10B74.1.
