| Years | 2008-2014 |
|---|---|
| Trims | US WRX 4-door and 5-door. 2008-10 WRX on the narrow Impreza body (the 2009 service manual covers body codes GE sedan and GH 5-door); 2011-14 WRX on the STI's wide body (Subaru's 2010 release; the 2012 manual covers GV sedan and GR 5-door). STI: 5-door only for 2008 (2008 pricing release); the 2012 manual covers STI sedan and 5-door codes. |
| Engine | WRX: EJ255 2.5-liter turbo; STI: EJ257 2.5-liter turbo (2009 and 2012 owner's manuals). 2009 WRX rated 265 hp (2009 release). |
| Notes | Bolt pattern splits by trim: every 2008-14 WRX is 5x100 and every 2008-14 STI is 5x114.3 (2012 and 2014 service manuals). The STI had already moved to 5x114.3 for 2005 (wheel guides), so this is not a 2008 change. WRX front brakes are floating calipers on a 294 mm vented rotor ('16-inch type'); STI uses Brembo 4-piston front and 2-piston rear calipers on 326 mm and 316 mm rotors ('17-inch type'). Wheel nuts: 100 N·m in the 2009-14 manuals (80-100 N·m in the 2008-09 owner's manuals). |

|---|---|
