Description
Toyota Sienta NSP170G (15+) VL BC Racing V1 Series VL Coilovers | 5/6kg.mm
BC Racing V1 Series VL Coilovers for the Toyota Sienta NSP170G (15+) VL deliver precision suspension tuning with a 5/6kg.mm spring rate, engineered to enhance handling and ride quality on UK roads. These performance coilovers feature a front setup without top mount and rear setup with rubber top mount, providing optimal geometry and comfort for your vehicle. Built to exacting standards, the BC Racing V1 Series offers the adjustability and reliability demanded by discerning drivers seeking genuine performance upgrades.
BC Racing V1 Series Coilovers
The BC Racing V1 Series coilovers use a large 44mm diameter piston in a 50mm diameter damper body to maximise oil capacity. As the damper operates, the oil inside heats up — the viscosity of oil changes with temperature, which can lead to changes in the damping characteristics of the unit. BC Racing use a very high quality oil throughout their range and go a step further by building the V1 with a 50mm diameter body. This increases oil capacity, reduces the peak temperature reached during use, and significantly improves damper performance and consistency as a result.

30-Way Damping Adjustment
A single adjuster controls both compression and rebound simultaneously across 30 positions, allowing the driver to set ride stiffness from a comfortable daily setting through to a firmer arrangement for track or spirited road use.
Ride Height Independent of Spring Preload
Ride height is adjusted via the bottom mount, not the spring platform — full damper travel is retained at any ride height. The tapered locking collar prevents the height setting from working loose under vibration.
This V1 VL configuration is supplied with OEM factory top mounts (reused) at the front and aluminium top mounts with rubber centres at the rear.
