Our comment: The Tein Street Flex coilover kit is a highly regarded offering from the popular JDM suspension manufacturer. This setup is likely to provide you with a slightly firmer ride than it left the factory with but providing substantial handling gains.

Tein have produced an optional-extra electronic dampening device, which connects exclusively to Tein coilovers. This allows you to adjust the 16-level stiffness inside the car to give you the perfect setting for street cruising or track racing at the touch of a button.

Manufacturer description:The Street Flex damper is the evolution of our popular Type Flex coilover. Developed to provide the ultimate balance of comfort and performance for both street driving and circuit use, along with wide-range damping force adjustment using our new Advance Needle technology and new damper valving specs, giving the driver a much more noticeable feel in damping force change and controllability.

The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Full-length adjustability offers separate spring preload and ride height adjustment. Updated internal components and external coatings increase durability and product life.

Our comment: BC Racing offer what could quite possibly be the best budget coilover kit available. If you’re planning to spend less than $1k, this all-round kit could well be the perfect choice for you.

These offer a firm, but not crashy ride which is still ideal for street use and are more than capable for the money when you head to the track. BC also offer their higher-end ‘ER’ series coilovers which are a competitior for the KW V3’s if you’re intending to do mostly track use.

Manufacturer description:The BR model is perfect for street driving and occasional road course duty. With easily accessible adjustment knobs for fine tuning your compression/rebound and separately adjustable ride height, having a performance coilover system couldn’t be any easier. You choose how low or high you want your vehicle, no preset ride height here, and our patented concave lower locking ring keeps it locked in.

All of our systems come with pillowball mounts to provide the most feedback possible from your suspension and to sharpen your steering response. BC’s available front and rear camber plates also allow you to get the perfect alignment setup without compromise. All this while providing a strong, attractive looking coilover system.

  • Purchase link: Buy HKS Hipermax III 370z Coilovers from FRSport

Our comment: Legendary Japanese tuning company HKS bring their hand with the highest price tag of our list. This option combines fantastic ride comfort which is close to stock comfort levels and fantastic handling alongside the typical quality you would expect from HKS.

These are a serious competitor for the KW V3’s and this may just boil down to personal preference, especially if you’re keen to maintain the JDM aspect on your car.

Manufacturer description:With the Hipermax III suspension series, the driver gains increased wheel control with improved performance of all vehicle dynamics and increased driver command in all conditions. Hipermax III combines track-quality control with excellent ride and handling characteristics at real-world street speeds.

HKS’ all-new Hiper Linear Piston Fluid Channel System damping system creates a positive relationship between piston speed and damping force, making it possible to produce a suspension that provides track-level control and feedback with exceptional ride quality at the same time. In addition, the Hipermax III is shock-body adjustable (most applications) to allow vehicle height adjustment without affecting spring rate and piston stroke. With the Hipermax III’s range of adjustability, precise corner balancing can be achieved. Chrome-plated cylinder shafts provide excellent durability and newly-design rubber upper mounts reduce harshness.

Our winner

Our winner is the highly acclaimed KW Variant 3 coilover.

It was a close call between the superb HKS Hipermax III and the KW V3’s, but with no way of faulting the hugely popular KW’s, they’re undoubtedly the best bang for your buck purchase on our list but either option certainly won’t disappoint!

For those with a serious budget who are looking to get the best lap times available, we have no doubt that the KW V3’s will be the ulimate choice. HKS Hipermax III and the BC Racing ER’s are undoubtedly fantastic alternatives if there’s any reason you would prefer to not go with the KW offering.

Runner-up

Another set of coilovers which really stood out during our research of this article were our budget-offering – BC Racing BR’s. At under $1k, we struggle to believe you will be able to find a better coilover out there for the money. If you’re still intending to make further upgrades to your car and looking for a cheaper alternative, we have no doubt that the BR’s will be perfect for your needs.
