The 2008-2011 Impreza, 2008-2014 WRX and STI (GR, GV, GH, GE) firewall is extremely thin. There probably was a reason Subaru made it this way, but it is hella inconvenient/annoying when they start squeaking, and downright dangerous when it fully fails.



The clutch and brake pedal assembly is mounted onto a bracket that is spot welded onto the thin firewall in 6X 5mm diameter spot welds. While the spot welds themselves are mostly good, and do not break at the welded joint, the thin firewall will get small 5mm diameter holes ripped off along with the welded joint through use of the clutch pedal. Forgive us for using our cars as intended Subaru (just kidding, I love you, please don't blow up on me)!
