Point
Suspension for 86 (BRZ) Street. Ver has been renewed.
By adjusting the suspension flexibly, the car can be gotten a grip of the traction, making it more comfortable to drive on the street.
In sports driving, the driver can actively control the load shifting and feel the movement of the car to enjoy control.
Although the movement has increased, the settings have been made to suppress abrupt changes in the movement even at the limit range, so that the driver can safely enjoy sports driving.
High durability of 3-year/60,000 km coverage has been achieved by reviewing internal components.
●About modification at the time of installation
Cutting rear interior is required to install the damper adjustment dial.
