Yokomo YD-2 SLF big bore shock tapered piston

For the YD-2 series of cars, Yokomo release these SLF big bore shock tapered piston. Developed by Team Yokomo drift members, one side of the piston surface has a tapered shape meaning the damping feeling differs depending on the mounting direction, softer for the movement of the piston in the direction of the taper. In addition, the piston hole is angled diagonally with respect to the shock operating direction so the damping changes with respect to a sudden shock input due to the action of fluid dynamics. At times it has the effect of absorbing small bumps while maintaining a high damping force. The piston hole setting is ø1.1 mm x 6 holes and each set contains 2 pieces.
