This is the third STI we've seen in the past few months with the firewall being severely damaged due to the clutch pedal assembly breaking. We got the firewall properly fixed and back on the road stronger than ever! 😎💪

📣PSA📣
We can't stress it enough on how critical a proper tune is. This customer brought their vehicle in after being "tooned" by a local shop. Engine was ran extremely lean with high detonation causing catastrophic failure.
