Used OEM GDB STI Struts with JDM Spec C Springs

Looking for factory STI handling without paying dealer prices? This full set of used OEM GDB STI struts fits the 2005–2007 Subaru Impreza WRX STI. In addition, it comes fitted with JDM Spec C springs, which give the car a sportier stance. As a result, you get genuine Subaru damping and a Spec C look in one simple bolt-on package.

What’s Included

This set covers all four corners. First, you get the front left strut, part number 20312FE380, and the front right strut, part number 20312FE370. Next, the matching rear pair carries part numbers 20360FE912 and 20360FE902. Finally, each corner comes assembled with JDM STI Spec C springs, so the set is ready to install as complete assemblies.

Why Spec C Springs?

Subaru built the Japanese-market STI Spec C as a lighter, more focused version of the GDB STI. Its springs give a firmer, more planted feel than standard US STI springs, while keeping the ride usable on the street. Many owners therefore choose Spec C springs as a subtle, factory-quality upgrade. Moreover, pairing them with OEM STI struts keeps the setup reliable and well-balanced.

Why OEM Struts Instead of Aftermarket?

Aftermarket coilovers can ride harshly and often need regular adjustment. In contrast, OEM STI struts give you the comfort and predictability Subaru engineered for daily driving. Also, a new front strut costs well over $300 per corner from Subaru. Consequently, a used OEM set offers excellent value for a factory-correct rebuild.

Fitment

• 2005–2007 Subaru Impreza WRX STI (GDB, 5×114.3 hubs)
• Not compatible with the 2002–2007 WRX or the 2004 STI (5×100)

Subaru’s catalog lists these front struts for 2006–2007 STI models. So, if you drive a 2005 STI, please send us your VIN and we’ll confirm fitment before you buy. For more on the car, see the Subaru Impreza WRX STI overview.

Used Condition

These struts are used, so please review every photo carefully, because they show the actual set you’ll receive. Also, we recommend a professional alignment after installation, since any strut change can shift camber and toe. That way, your STI drives straight and wears its tires evenly.
