TEIN Flex Z Coilovers are the latest generation of high end coilovers. The difference with Flex Z is that you are getting a coilover that would normally cost double the price. The new manufacturing systems that TEIN has put in place with this coilover has allowed them to produce these coilovers at lower prices and pass that savings on to you. Quality and performance remain a top priority. TEIN builds these Flex Z coilovers with the highest standards.

TEIN Flex Z coilovers have an awesome twin tube internal system that gives you one of the best street rides from any coilovers. In addition, the full length height adjustment system enables you to lower the car to the max allowable level and still maintain the same shock travel and ride quality.

TEIN Flex Z coilovers are 16 way dampening adjustable (compression and rebound together) so you can made the ride stiffer or softer depending on what sort of ride quality you are wanting. For example, you can set the dampening to a low setting for when you are daily driving the car and set it up to a stiffer setting for track days or spirited driving.

These coilovers include upper mounts for each installation. Each kit comes with either reinforced rubber upper mount or a pillowball upper mount. Pillow ball upper mounts are for strut suspensions and include front camber adjustment.

TEIN takes pride in their products and each one is built to be the best quality possible. TEIN coats each Flex Z with “”ZT Coating”” that prevents rust and has multiple layers to ensure the best finish.

TEIN Flex Z Coilovers Specs and Features:

  • 16 Levels of dampening force adjustment
  • Twin-Tube for Comfortable Street Ride
  • Full-Length System for Height Adjustment with minimal change in ride quality even at lowest setting
  • EDFC Compatible (uses M12-M12 Motors)
  • Includes Upper Mounts for Easy Installation (some vehicles use OE mounts)
  • Includes Dust Boots (some vehicles use OE dust boots)
  • TEIN Quality for durability, reliability and rust proofing
  • No-Sag Springs

Spring Rates:

  • Front: 7K
  • Rear: 6K

Incredibly Low Price
The top end of the shell pipe is narrowed, oil and gas are injected, and the whole unit is sealed by crimping the metal.

This new approach massively shortens the production process. As a result, we have succeeded in vastly cutting production cost.

Thread-Type Ride Height Adjustment
The ride height can be adjusted by moving the lower spring seat up or down. Characteristic of this system are its simple structure and ease of use.

Twin-Tube System
Compared to the regular mono-tube system, twin-tube attains longer stroke with a smaller repulsive force, resulting in high ride comfort.

Roads may have all sorts of surface conditions. This calls for shock absorbers with ample stroke, that operate smoothly.

Thanks to this unique characteristic, you can negotiate gaps and bumps steadily on rough roads, meaning a smooth ride at low speed and stability at high speed.

Uses OE Mounts
STREET ADVANCE Z and STREET BASIS Z use the vehicle’s original upper mounts (not included in our product kit).

High Durability and Reliability
Optimal Dust Boot – Thanks to its smooth compression and high durability, the dust boot guards the piston rod from damage, and keeps foreign material out of the shock absorber. (Some vehicles use their OE dust boots)

No-Sag Spring – Cold formed with SAE9254 steel (minimum tensile strength 200 kgf/mm2), our springs are outstandingly sag-proof and boast extreme resiliency. Superior rust protection is ensured with a highly durable powder coating that does not peel or flake. Our high-quality springs can be used without worries, in any conditions.

High-Performance Damper Oil – Since TEIN’s damper oil maintains a stable viscosity in a broad temperature range, it sustains smooth stroke and reliable damping force in a variety of circumstances. Due to excellent anti-foaming properties, it’s resistant to cavitation (bubble forming). Since it withstands high heat too, it’s suitable for intense sport driving as well. Furthermore, the damper oil keeps up its superior performance long-term, because it’s resistant to deterioration over time.

Rust-Proofing – A bright TEIN-green powder paint is used on the shock absorber’s shell case. Our powder coating technique produces an extremely strong and durable barrier. No harmful organic solvents are used, for minimal pollution. Superior durability and corrosion resistance are achieved by TEIN’s patented 2-Layer, 1-Bake powder coating method, which uses 2 layers of anti-rust paint on a blasted surface.

Special Surface Treatment ‘ZT Coating’ – Our unique ZT Coating surface treatment on the ride height adjustment thread is abrasion resistant against gravel/debris, and further enhances its corrosion resistance. With zero claims for stuck parts due to rust in 500,000 shock absorbers, TEIN shock absorbers are amazingly rustproof. We’re confident of customer satisfaction even in coastal areas or regions with heavy snowfall.

Damping Force Adjustment
Modify ride comfort and handling according to your preference, changing the properties of the shock absorber with the adjustment dial.

Compatible with EDFC Series (Optional)
The EDFC Series offer easy damping force adjustment from the driver’s seat

    The BC Racing RM series feature high quality damping adjustable mono-tube inverted dampers at the front or front and rear, depending on vehicle. The RM coilovers offer the majority of the features of the BR series but with the additional benefit of the inverted damper unit. Inverting the damper unit brings with it a number of advantages.

    REDUCED HEAT TRANSFER TO THE GAS AND OIL RESERVOIR

    Any hard driven car with generate a lot of heat within its braking system. This heat is conducted through the hub to the damper unit. By inverting the oil and gas reservoir the oil and gas is moved away from the hub assembly . This reduces the amount of conducted heat being transferred from the braking system to the hub then to the damper and then on to the gas and oil. As the oil and gas is heated its properties change which has a knock on effect on the damping characteristics of the suspension. By keeping the gas and oil temperatures down BC Racing RM coilovers keep damping rates more consistent resulting in better performing suspension and ultimately allowing you to corner faster, which is the bottom line. REDUCED FLEX

    The large 42mm damper rod and inverted design gives the inverted damper units much greater strength and resistance to side loadings. By reducing flex the RM inverted units lead to more consistent steering geometry resulting in more predictable and responsive handling. RM SERIES INVERTED COILOVER
