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.)

Point

The stock suspension is comfortable and has a good feeling of flexibility, which makes it fun to control the vehicle's movement and force, but it is a little stiff in the rear and roll is too large even in SPORT mode.
With this kit, the amount of roll is reduced to achieve a lighter cornering. In addition, the lowering not only gives the Si the right look, but also improves the comfort.
Like the S660, the front suspension has a severe stroke structure. For the ultimate performance, we designed the product without adjustment functions the overall length, and the internal structure was further improved. HKS's traditional inverted mono-tube is selected. It provides rigidity and stroke capacity.
This kit Includes the upper plate adjusting bolts for front camber alignment. The camber can either be fixed at the stock standard position or adjusted by ±0.5°.
A cable for rear damping adjustment is provided as standard equipment, allowing simple damping adjustment without having to jack up the car or remove the damper, as is often the case with other manufacturers. Directly wound barrel type springs allow more freedom in setting.
Compared to the regular HIPERMAX series, this product has a more comfortable ride, but unlike the regular grade products, this Si is specially designed to reduce rear roll. We pursued the best balance between comfort and handling.
When you tighten the damping dial, you get a more solid feeling. If you prefer solid feeling, or when driving at high speed, you are free to adjust it according to your preference.
You can avoid the displayed error when the stock suspension is removed by installing a canceller (optional ).
Note: It is required to remove the front knuckle and the hub assembly to remove the stock suspension. We recommend that you have the product installed by an auto mechanic at a professional store, mass retailer, or dealer.
