KW

The best KW parts in this collection are its coilover kits: the V3 for the 2009-2024 Nissan GT-R, 2023-2024 Toyota GR Corolla, and 1992-2000 Honda Civic, the V3 Clubsport for the 2023 and newer Honda Civic Type R (FL5), and the V1 INOX-LINE kit for the 2008-2014 Subaru WRX, plus the H.A.S. spring kit and damping cancellation kit for the 2009 and newer GT-R. Check your year and model before ordering, because every kit here is built for one specific application.

KW gives shoppers three ways to lower and sharpen a car. A full coilover kit replaces the factory struts and springs as a matched set, a height adjustable spring kit keeps more factory hardware while adding ride-height adjustment, and a damping cancellation kit supports a coilover swap on a car with electronic factory damping. Start in the wider suspension range if you are still deciding which route fits your build.

KW is the single brand here, organized by kit family. The V1 kit for the 2008-2014 WRX is the entry point, the V3 kits cover the GT-R, GR Corolla, and 1992-2000 Civic coupe, hatchback, and sedan, and the V3 Clubsport is the Civic Type R (FL5) option. The GT-R also gets two supporting pieces: the H.A.S. spring kit and the electronic damping cancellation kit, both for 2009 and newer cars.

TEIN is the Japanese name shoppers most often cross-shop against KW for street coilovers on Subaru, Honda, and Toyota applications. It is the natural comparison when weighing a European kit against a Japanese one.

BC Racing is the value-minded alternative, with a large coilover catalog covering many of the same WRX, Civic, and GT-R applications. Shoppers usually compare it on price and availability against KW's stainless V1 and V3 kits. For lowering without a full coilover swap, compare the lowering springs range as well.

Silver's North America rounds out the comparison set with its NEOMAX coilover line for Japanese performance cars, in the same conversation as KW for daily-driven builds. Our guide to buying coilovers for your Subaru walks through how to choose between these routes.

What is the difference between the KW V1 and V3 kits here?

Both are complete coilover kits, split by application: the V1 INOX-LINE kit is listed for the 2008-2014 WRX, while the V3 kits cover the GT-R, GR Corolla, and 1992-2000 Civic, with a V3 Clubsport for the Civic Type R (FL5).

Should I choose the H.A.S. spring kit or a full coilover kit for my GT-R?

The H.A.S. kit is a height adjustable spring kit for the 2009 and newer GT-R, while the V3 is a complete coilover kit for the 2009-2024 GT-R. Choose springs for ride-height adjustment alone, and a coilover kit to replace dampers and springs as one matched set.

What does the electronic damping cancellation kit do?

It is listed for the 2009 and newer GT-R alongside the coilover kits, for cars whose factory damping is electronically controlled. If your GT-R has that system, check whether your coilover build needs it before ordering.

Do I need an alignment after fitting KW suspension?

Yes. Any coilover or spring kit changes ride height and suspension geometry, so a professional alignment after installation is recommended. No engine tune is required for these suspension parts.
