PSS pistons with factory drilled 0.8mm holes (2 in each piston).
The drilled PSS pistons makes it possible to use thicker shock oil, while still retaining a lighter damping feel.
A thicker shock oil stays more consistent for hot conditions especially, which makes the car’s grip drop off less throughout the run – which is particularly important for asphalt surfaces on hot day.
Allows for a heavier shock oil to be used, for a more consistent handling. To be used with a PSS shock system for ULP shocks 308029 and SLP shocks 308039. Set of 4.
