Construction & Design

The SPEC Stage 2+ Clutch Kit features a meticulously engineered multi-friction disc that combines different friction materials to optimize performance across a range of driving conditions. The full-faced design ensures even pressure distribution and reduces the likelihood of uneven wear. The clutch cover is constructed from durable materials and heat-treated to resist warping and fatigue, ensuring longevity and consistent performance. The inclusion of a sprung hub helps absorb vibrations and shocks, resulting in smoother engagement and a more refined driving experience.

The components are assembled with precision, utilizing TIG welding and CNC-machined parts to ensure perfect fitment and durability. The design emphasizes heat dissipation and reliable operation, even under demanding conditions, making this clutch kit a trusted upgrade for enthusiasts pushing their vehicles beyond stock power levels.
