VS Mitsubishi Diamante (JDM) F34A 1995-2005 - B-33-V1-VS - The V1 series coilovers use a large 44mm diameter piston in a 50mm diameter damper body to maximise oil capacity. As the damper unit opearates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit. BC Racing only use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their V1 range with a large 50mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance. Key Features: Pillowball top mounts Bearing mounted upper spring platform 30 way adjustable damping Ride height adjustment separate to spring preload Camber adjustable top mounts (depending on model) Tapered bottom mount locking collar to prevent collar working loose Monotube damper design Custom spring rates available All spare parts available with low lead times Dust boot to protect the damper seal
