Point
To compensate for the genuine suspension which becomes inadequate in low and flattening and high grip caused by using a larger tires, the balance of the stroke amount and the damping characteristic is mainly reviewed by testing with 20 inch wheels to achieve high speed touring performance taking advantages of tires characteristics.
Experience the driving that is inevitable with the design of this new Crown which became the sportiest appearance in the past.
※After lowering the vehicle height, the irradiation range narrowness of a radar camera and misalignment of alignment center may occur that result in malfunction of Toyota Safety Sense (TSS). HKS will not be responsible for any accident caused by TSS malfunction after installing this product.
※Modification of the rear inner fender is required in order to install this product.
●The straight ID65 springs are utilized for both front and rear sides. Replacing the spring widens the setting ranges according to the purpose of driving.
●The front and rear lower brackets are aluminum billet type, and the front bracket is totally new design.
