Limited GRK5-R HRP / SDC Championship Edition chassis

The GRK5-R HRP / SDC Championship Edition is a limited edition developed by SHIBATA GRK RACING to celebrate its victory at the Super Drift Competition (SDC) in the United States.

Produced by Hayato Yoshiba, official SHIBATA GRK RACING Factory driver, this chassis uses the geometry and suspension setup developed for competition, while integrating as standard a selection of the latest performance parts from SHIBATA.

Unlike the standard GRK5-R, this Championship Edition directly receives numerous options dedicated to the drivetrain, steering, suspension, and weight distribution. The HRP chassis conversion kit is notably installed as standard.

This version was designed to reproduce as closely as possible the development philosophy, geometry, and setup that allowed SHIBATA to win the SDC.
