The adjustable lower mounts are made from steel, ensuring a solid and secure connection between the vehicle and the strut.
The BC Racing J-39-BR coilover kit is also equipped with adjustable rebound and compression damping. The rebound adjustment can be found on the top of the shock body, while the compression adjustment is located at the bottom. This allows you to fine-tune the shock absorbers to suit different driving conditions and preferences, ensuring the best possible driving experience.
Installation of the BC Racing J-39-BR coilover kit is relatively straightforward, with most installations taking between 3 to 6 hours.
