From the seller

● World's first high-tech spring that can be cut.

● Cutting up to two coils is OK.

● As long as the minimum ground clearance (90mm) is cleared and there is no play, it will pass vehicle inspection.

● Spring rate is within 5-10% of the original. Emphasis on ride comfort.

● Almost no sagging. 3-year warranty.

● Uses a new material with a tensile strength of 200kgf/mm2.

● Uses environmentally friendly paint. Industry first.

◆Installation Requirements

★1 Before starting work, please check that the dimensions and shape of the upper and lower parts of our spring are the same as the spring on the vehicle. This can be determined by appearance.

★2 When assembling the coil spring, pay attention to the top and bottom. (Our mark may be reversed. Please be careful.)

★3 When adjusting the ride height by cutting the coil spring, cut only up to the second coil from the tail end where the spring is tightly attached. Never cut beyond the allowable range.

★4 When cutting coil springs, use a grinder or hacksaw, and be extremely careful not to damage any parts other than the cutting point. Damaged springs are extremely dangerous and should never be used.

★5 When adjusting ride height by cutting coil springs, the vehicle will pass inspection if a minimum ground clearance of 90mm is maintained.

★6 As a guideline for ride height adjustment by cutting springs: Kei cars → approximately 10mm drop; Regular cars → approximately 15mm drop.

★7 When cutting springs, first install them without cutting, check the ground clearance, and then determine the desired drop amount before cutting.

★8 Never cut coil springs before installation.

*If seawater or de-icing agents come into contact with the product, it may cause corrosion, so please wash it off immediately and apply a rust inhibitor. This may cause a decrease in function or breakage.

*Product prices and specifications are subject to change without notice.

*Do not drop or subject the product to strong impacts before or during installation. Also, when using a spring compressor or similar tool during installation, please be careful not to scratch the product.

*When adjusting the ride height by cutting the Super Downforce C, be sure to install it once beforehand. Please check the vehicle height before determining the adjustment amount and performing the work. Please note that we cannot accept any claims after cutting, regardless of the reason. Never cut the springs before installation. Doing so will void the warranty.

*Please cut the springs at your own discretion. When cutting, be careful not to damage any areas other than the cut point, as this may cause breakage. Also, never weld the springs.

*Before starting the disassembly work, please be sure to check that the shape of the product you purchased matches that of the normal springs. If you have any questions, please contact the manufacturer or our company before installation.

*After installing the product, please re-check the alignment and make adjustments to suit your vehicle.

*After installing the springs, you may hear unusual noises when going over bumps in the road. This is due to the spring coils being compressed and does not indicate any functional problem.

*Depending on the situation, it may be better to cut the bump stops.
