Point
Suspension made for sportier driving GR series vehicle.
Stiffer compared to stock ride is still well balanced to maintain comfort and remain family use friendly.
In hose made rubber upper mount makes possible adjustment of rear damping force. Now it is possible to select softer or stiffer damping to your liking based on situation.
Rear dampers use straight springs that can be easily switched to universal spring.
Rear lock seat moved above the ride height seat, rubber seat that was in place above ride height adjuster is now absent.
In case of use of higher rate springs, there is enough space for helper spring. We recommend combined use with helper spring as it allows stroke adjustment as well, making it possible to make even finer setting.
