Product Details

Yellow Speed Racing Advanced Pro Plus Circuit Spec 2-Way Coilovers for the 2004-2011 Proton Gen-2 Hatchback are a motorsport-grade suspension developed for competitive circuit racing. This is part number YS01-PT-ASCR001.

Each kit is built to order with vehicle-specific valving and spring rates tailored to high-grip tarmac use. The system uses a monotube damper with a high-precision remote reservoir for added oil capacity and thermal stability, and CNC-machined components and aluminum shock bodies to reduce unsprung weight. It is not recommended for street use because of the stiffer valving and higher NVH.

Features

  • 2-way adjustable damping with independent compression and rebound adjustment
  • Monotube damper design with an external remote reservoir
  • Custom spring rates and valving
  • CNC-machined components and aluminum shock bodies to reduce unsprung weight
  • Camber adjustable top mounts on applicable models
  • Hand built and made to order
