‹ÄÈThe product is evolved further based on Hipermax III Sports 09 Spec.
‹ÄÈFor further performance improvement, this product was developed with latest parts such as new shape needle, M-shaft, aluminum bracket, etc. based on Hipermax IV GT.
‹ÄÈThis product utilizes an adjustment dial that allows various driving conditions from street to circuit with high grip radial tires.
‹ÄÈTo maintain the stability in rear and traction performance, the spring rate is reduced, and the rate balance in front and rear are optimized.
‹ÄÈSettings for smooth turning and quick acceleration at a clip point are performed exclusively for Lance Evolution.
‹ÄÈCarefully choosing the stroke distribution and damping force setting achieves a high-level sporty driving performance. Stability and controllability in the critical area are also concerned.
‹ÄÈRecommended dial position for sporty driving is 15 in front and rear. Adjust the dial to 25-30 for street driving to provide relaxed feeling to a fellow passenger.
‹ÄÈWhen adjusting the rear damper, to avoid the damper from coming in contact with the arm resulting in damage, do not make the case length shorter than 411mm and the vehicle‰۪s rear height lower than -33mm.
‹ÄÈSince the front damper is close to the front tire and wheel, make sure the damper does not come into contact with any other parts of a vehicle when lowering the vehicle height. If the damper comes into contact with any other parts of a vehicle, slide the tire wheel outward using a wheel spacer or a similar tool.
