The Kyosho W5307-07GM spring sheet is a 14mm gunmetal aluminum shim crafted to refine V-One R4 suspension. It is aimed at drivers who need repeatable handling when changing track lines or tyre compounds.
These shims are sized to alter spring pre-load and seating characteristics, giving you cleaner feedback through corners. Their stiffness helps reduce unwanted spring movement, which improves predictability when pushing lap times.
Manufactured from high-grade aluminum, the W5307-07GM provides a tough platform that resists deformation. The gunmetal finish adds protection against corrosion while keeping a low-key, professional appearance.
Made to match the V-One R4 geometry, installation is straightforward and does not require chassis modification. Use them to replace worn parts or to fine-tune your current suspension package.
