    HKS Max IV GT Coilovers Corolla HB 19+ 80230-AT016

     

     

    Single Tube Damper Design

    Monotube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and center of gravity gives a more stable ride.

     

    Dust Boot

    Protect the shaft from the flying stones.

     

    PNE Coating

    Using this special surface coating provides 5 times better durability over standard galvanizing. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.

     

    "M Shaft"

    With the new design of cylinder shaft since the HIPERMAX M-1, MAX IV increased the cylinder shaft size to have a firm damping even at a little stroke range because of the optimized oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.

     

    New Design Needle

    Newly designed needle has been used to revise the very low speed and middle and high-speed dampening which is key to a comfort ride.

     

    Reduction of Unsprung Weight

    In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminum. (Not for all vehicles)

     

    30 Step Damping Force Adjustment

    30 levels of dampening adjustment allow fine tune adjustment for street or circuit.

    *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.

    Point
    The stock suspension is well-matched with the high rigidity TNGA body.
    This suspension is designed to derive the further potential of the high rigidity TNGA body. Tightening the dial enables the driver to experience the sporty performance Corolla Sport can achieve.

    ※After lowering the vehicle height, the irradiation range of a millimeter wave radar and monocular camera may become narrow that result in malfunction of TSS.
    HKS will not be responsible for any accident caused by TSS malfunction after installing this product.

    ●The setting range widens by replacing both front and rear stock springs with HKS direct coiled springs
    ●The rear upper mount has a drain hole.
    ●The dial is located at a lower side of the front damper and inside the rear fender behind the wheel well for easier dial adjustment.
    ●The stock rubber seat can be installed to the upper and lower side of the rear spring to suppress the generation of an abnormal noise.
