Parts List * It may be changed without prior notice. Point - Although the suspension design is the same as the 1st gen 86/BRZ and 2nd gen BRZ, the coilover has been re-tuned specifically to enhance the characteristics of the GR86 since the OEM suspension settings are different for each car model. - After much trial and error in selecting the spring rate, we decided to use a newly designed rear spring which is different from the 1st gen 86/BRZ (80300-AT001 F:5.0k, R:5.0k) and 2nd gen BRZ (80300-AF020 F:5.0k, R:6.0k), and set the spring rate at F:5.0k, R:6.5k for the GR86. - It does not spoil the characteristics of GR 86, which has sharper handling performance than the 2nd gen BRZ. - The shock absorber with 30 adjustable damping force adjustment dials allows the driver to ride comfortably and smoothly on daily driving with the soft setting, and to enjoy performance driving with the hard setting. - The test was conducted with the stock 17-inch tires as well as the ADVAN FLEVA (performance summer tire) and ADVAN NEOVA (track day and competition summer tire). - Highly durable with a three-year warranty by using the latest internal components.
