(Special Order) Utilizing the latest technology, we have succeeded in achieving a higher spring rate, while keeping everyday use in mind, and have been able to improve driving performance. The structural weaknesses of the rear have been resolved with new dedicated parts, allowing for a wide range of vehicle height adjustment and the use of longer springs. Compared to the MAX IV SP, the shape has evolved to make vehicle height adjustment easier, as it does not require removing and installing the springs to adjust the rear height. The adoption of a new dedicated rear part, the helper spring, ensures sufficient extension stroke, and is designed to increase grip of the inside rear tire on the circuit.

Height at factory is the data tested at HKS with the setting of Full Kit. (HKS’ recommended setting.) 3. Adjustable range (However, the lowest value may not be road legal. Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive. Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.) 4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.) Caution). Actual data depends on each vehicle.
