Used Tein Mono Sport Coilovers for Subaru Impreza GD (5×100)

Want sharper handling and adjustable ride height without paying full price? These used Tein Mono Sport coilovers, part number G7S28-1AYA1, fit the 5×100 Subaru Impreza GD chassis, including the 2002–2007 WRX sedan. The set includes all four corners. As a result, you get Tein’s proven monotube design for a fraction of the cost of a new kit.

Why Choose Tein Mono Sport?

Tein has built performance suspension in Japan for decades, and the Mono Sport sits in its street-and-track lineup. First, it uses a monotube damper, which runs cooler and gives more consistent feedback than a twin-tube shock. In addition, 16 levels of damping adjustment let you go from a comfortable street setting to a firm track setup in minutes. Moreover, full-length height adjustment lets you set ride height without compressing the springs. That way, you keep full suspension travel and a better ride.

Key Features

• Monotube dampers for consistent, fade-resistant performance
• 16-level damping adjustment
• Full-length ride height adjustment
• Camber-adjustable front upper mounts
• Compatible with Tein EDFC (Electronic Damping Force Controller)
• Rebuildable and revalvable by Tein

Fitment

This set fits the 5×100 Subaru Impreza GD chassis, including:

• 2002–2007 Subaru Impreza WRX sedan (GDA)
• JDM Impreza GD models with the 5×100 hub

Tein also lists a similar US kit for the 2002–2007 WRX under part number GSS28-71SS4, so you can use that number for reference. However, 5×114.3 STI models (US 2005–2007) use a different kit, so these won’t fit them. Also, wagon (GG) owners should call us to confirm rear fitment. If you’re unsure, send us your VIN and we’ll check before you buy.

Used Condition

These coilovers are used, so please review every photo carefully, because they show the actual set you’ll receive. Also, Tein can rebuild Mono Sport dampers when they need refreshing, which gives the set a long service life. After installation, we recommend a professional alignment to set camber and toe correctly.
