Amelia J. ★★★★★

Snapped right onto the factory bumper holes on my 2012 sedan with zero trimming needed. Fitment is spot on and it completely changed the look of the rear end. Just wish it wasn't so hard to find in stock.

Joshua ★★★★★

Was worried I'd have to drill new holes in my bumper but this bolted right up to the factory mounting points on my 2012 STI sedan. Fitment is spot on with zero trimming needed. Looks way more aggressive from the rear now.

Penelope ★★★★★

Snapped this on my 2013 sedan and it lined up with the factory bumper holes perfectly, no drilling or trimming needed. Wasn't sure about fitment since it's discontinued, but it sits flush and looks way more aggressive from the rear.
