Point
Refined low-stance is created while maintaining the factory's supple ride feeling. Appropriate amount of roll backed up with a supportive and stable feeling creates secure and predictable handling. Some professional drivers tried this product for magazine articles and praised it for the highly reliable controllability. The gradual damping force and natural roll are focused while driving with this product. The product provides a great ride quality not only for those who enjoy street driving but also circuit driving.
(※To avoid a feeling the stiffness at a large gap, reduce the spring rate by 1kg; the rear stability may be the same as the stock, but the ride comfort will be improved.)
※If the front stabilizer is replaced with a bigger one, make sure the stabilizer does not come in contact with the damper.
※For an automatic transmission vehicle, resetting referring to the data shown in the provided manual is required for the optimal performance.
