Even if you use the car on a daily basis without using it in a special way, the underside of the car will deteriorate. If you neglect to take measures against deterioration of the lower part, the pace of parts replacement of the muffler and undercarriage may become faster, and in the worst case, it may be necessary to replace it without passing the vehicle inspection. We recommend the installation of three rasters to prevent deterioration of the car and rust erosion. Especially recommended for those who use winter highways, coastal areas, and snowy roads!
