Information:

• Many small cars and Kei Cars come equipped with 15–18 inch wheels, which leaves limited internal space within the wheel hub. Traditional multi-piston calipers often cannot be installed due to their large size, causing interference with the wheel and preventing upgrades to high-performance braking systems.

• To overcome the limitations of installing multi-piston systems on smaller wheels, we developed the patented Single-Sided Piston Caliper Upgrade System, based on the thickness standards of OEM single-piston calipers. This design maintains the original caliper installation space while delivering multi-piston-level braking performance and visual appeal—making it the ideal choice for drivers who want to retain the OEM wheel design but enhance braking performance.

• The system uses an OEM-style single-sided floating caliper structure, effectively reducing vibration while maintaining excellent stability. The forged aluminum caliper body, paired with enlarged brake pads, significantly improves stopping power and heat resistance. The standard two-piece ventilated rotors reduce unsprung weight and enhance cooling efficiency, further improving overall braking performance.

• Four rotor sizes are available: 286×22 mm, 304×22 mm, 330×22 mm, and 350×22 mm, fully compatible with 15–18 inch wheels, perfectly meeting the upgrade needs of small OEM wheel sizes.

• Despite its slim profile, the caliper retains the bold, multi-piston appearance and sporty styling, offering both performance and aesthetic appeal. This design is patented worldwide and all rights are reserved.
