Toyota Sienta NSP170G BC Racing Coilovers

BC Racing V1 Performance Coilovers for the Toyota Sienta

Developed for Sienta NSP170G 2015-Present Jdm, this BC Racing V1 coilover kit provides the adjustment and suspension control needed for fast-road driving and occasional track use. The kit replaces the original suspension with a vehicle-specific setup designed to reduce body movement, sharpen steering response and provide more consistent control during braking and cornering.

BC Racing suspension systems are developed with performance use in mind. Recommended specifications are designed to provide a usable balance between road comfort and track capability. Different series and configurations are available to suit daily driven vehicles, fast-road builds and more focused track projects.

Adjustable to Suit Your Vehicle

Depending on the selected application, the suspension may allow the driver to adjust ride height and damping response. This makes it possible to refine the setup around the road surface, tyre choice, driver preference and vehicle use.

BC Racing coilovers can also be supplied with different spring specifications for some applications. Spring rate changes should be discussed with Paramount Performance before ordering, particularly where the intended rate differs considerably from the standard specification. A substantial change may require revised damper valving to maintain balanced suspension performance.

Track Preparation

A full wheel alignment is recommended after installation and following any substantial ride height adjustment. Corner balancing can further optimise a heavily modified or track-prepared vehicle, although it is normally unnecessary for everyday road or show use.

Suspension installation and setup should be completed by a suitably experienced technician. Always check wheel, tyre and bodywork clearance before driving the vehicle.

Available from Paramount Performance, established performance specialists since 1986.
