BC Racing BR-RN coilovers for Toyota BZ4X

This new BC Racing BR-RN coilover kit is intended for the Toyota BZ4X, improving handling while offering extensive height and firmness adjustment. Drawing on BC Racing’s motorsport experience, these Club Sport BR coilovers offer a versatile solution for drivers seeking better body control, optimised stance and more precise driving.

Purpose of the part
