The length of the stabilizer link is designed with using the factory suspension height of your Mazda 6. Due to this when lowering the car height this changes the position of the lower arm creating an angle with the stabilizer end link. This can change the way the stabilizer functions if not corrected. The adjustable link is an item which allows the true stabilizer functionality to shine through by adjusting the link length when lowering your Mazda so that the arm angle of the stabilizer is kept at the appropriate setting.

The end links include installation instructions which are in Japanese and are sold in pairs
