Tein 00-05 Mitsubishi Eclipse D52A/D53A Street Basis Z Coilovers

Dial In Your 00-05 Mitsubishi Eclipse D52A/D53A Ride Height Without Losing Everyday Comfort

The Tein GSR70-8USS2 Street Basis Z coilover kit gives owners of the 00-05 Mitsubishi Eclipse D52A/D53A a straightforward way to lower ride height and sharpen handling while keeping the car comfortable enough to drive daily. Built around Tein’s twin-tube damper design, the GSR70-8USS2 kit favors a longer stroke and smaller repulsive force, so the car stays smooth at low speed and settled at highway speed. Ride height is adjustable through the lower spring seat, letting you fine-tune stance and corner balance after installation. The GSR70-8USS2 uses the vehicle’s factory upper mounts, which keeps the install straightforward and the parts count low.

Key Features

• Twin-tube damper construction for a longer stroke, smaller repulsive force, and smooth low-speed ride quality
• Ride height adjustable via the lower spring seat for easy stance and corner-balance tuning
• No-Sag Spring made from cold-formed SAE9254 steel with a minimum tensile strength of 200 kgf/mm for long-term ride height retention
• Durable powder coating engineered to resist peeling and flaking over time
• Sealed shell pipe construction (narrowed top, oil/gas injected, crimped seal) for cost efficiency without cutting corners on quality
• High-performance damper oil formulated for stable viscosity, anti-foaming, and cavitation resistance across a wide temperature range
• TEIN-Green two-layer, one-bake powder coating (Japanese patent 4347712) applied without harmful solvents
• ZTP-coated ride-height adjustment thread that resists abrasion and corrosion to help prevent rust-seizure

FAQ

What is the GSR70-8USS2?

The GSR70-8USS2 is a Tein Street Basis Z coilover kit built for the 00-05 Mitsubishi Eclipse D52A/D53A. It replaces the factory struts and springs with a twin-tube damper and adjustable lower spring seat, letting you lower the car and tune ride height while keeping a comfortable street ride.

Is the damping force adjustable on this kit?

No, the GSR70-8USS2 Street Basis Z kit uses a fixed, non-adjustable damping setting. Owners who want a dial-adjustable damper should look at the Street Advance Z line instead.

Does this kit use the factory upper mounts?

Yes, the GSR70-8USS2 is designed to reuse the vehicle’s OE upper mounts, which are not included in the kit.

How much can I lower my vehicle with this kit?

Ride height is adjustable through the lower spring seat, giving a usable range for a lowered stance. Exact drop depends on the vehicle and how the coilovers are set, so aim for a setting that keeps suspension geometry and tire clearance in mind.

Is this kit compatible with Tein’s EDFC electronic damper controller?

Street Basis Z is generally EDFC-compatible on applicable vehicles, though some platforms are excepted. Check current compatibility before ordering an EDFC controller for your specific vehicle.

Will this coilover kit hold up to daily driving?

Yes, the GSR70-8USS2 was designed for street use. The twin-tube damper and No-Sag Spring are tuned for comfortable daily driving rather than track-only stiffness.

Does the kit include new springs?

Yes, the GSR70-8USS2 ships with a matched set of Tein’s No-Sag Springs already mounted on the dampers.

What is the spring made from?

The No-Sag Spring is cold-formed from SAE9254 steel with a minimum tensile strength of 200 kgf/mm, designed to resist sag and hold ride height over time.

Install Instructions

1. Raise and safely support the vehicle, then remove the wheels.
2. Disconnect the factory brake line bracket and any sensor wiring attached to the strut, then remove the factory struts and springs from the vehicle.
3. Confirm the lower spring seat position on the GSR70-8USS2 damper for your target ride height before installation.
4. Transfer the vehicle’s OE upper mount to the new Tein damper if the mount is not integrated into the kit.
5. Install the Tein coilover assembly into the strut tower and lower control arm, torquing all hardware to factory specifications.
6. Reconnect the brake line bracket and any sensor wiring, then reinstall the wheels.
7. Lower the vehicle and bounce the suspension to seat the components before a final ride height check.
8. Have an alignment performed after installation to bring camber and toe back into spec.
