R31 House GRK5-R HRP Conversion Chassis Kit Black

This is R31 House GRK5-R HRP Conversion Chassis Kit Black. Introducing the GRK5-R Conversion Chassis Kit, the first release from HRP (HAYATO Racing Performance) — a competition-focused brand developed exclusively for the GRK series and supervised by HAYATO, ace driver of SHIBATA GRK RACING. Engineered to meet HAYATO’s uncompromising performance demands, this kit is designed specifically for competitive driving with the GRK5-R platform. 

To fulfill HAYATO’s strict requirements, a specially commissioned carbon fiber material is used, custom-manufactured at a domestic Japanese factory. This ensures an exceptional balance of rigidity, strength, and weight reduction for high-level racing performance.

The main chassis eliminates the remaining general-purpose elements found in the standard design, resulting in a GRK5-R layout–specific chassis that achieves both increased rigidity and reduced weight.

Versatility is sacrificed in favor of pure performance.
