・In stock “Normal” mode, the rear of the vehicle is noticeably harsh and uncomfortable, and the ride quality lacks a sense of luxury, despite the vehicle's size
・The stock sport mode gives a good feeling of damping, but it is not well matched with the springs and causes a buzzing vibration.
・The feeling of the ride changes by switching modes, but none of the modes provide a high quality and luxurious ride.
・For the target of this kit, we decided to combine the handling of the sports mode with the luxurious ride quality without the lumpiness of the normal mode and to cover the sports + area by adjusting the settings.
・When the product is delivered, it is adjusted down by 1 inch compared to the stock in order to achieve an elegant style without lowering too much. The beautiful flowing body lines are enhanced, and the car is reborn as a wild and elegant sports coupe.
・By absorbing uncomfortable vibrations, we have ensured a comfortable ride without feeling tired even after long hours on the freeway. We have pursued a fun feeling that makes you want to drive endlessly.
・In pursuit of the best balance between handling and ride comfort, the spring rate has been carefully selected. It is supple enough to handle rough urban road surfaces, railroad crossings, manhole bumps, swells at intersections, and other uncomfortable situations.
・The rear damping force adjustment cable is included in the kit. Easy access from the trunk for adjusting the damping force.
・Full-length adjustable, large-diameter piston mono-tube, original rubber upper.
