Direct fitment is no joke here—it lined up perfectly with the factory bumper holes on my GT, zero gap or fuss. The whole thing feels solid and changes the rear stance completely, sad it's out of production but glad I grabbed one.

Adam ★★★★★ Aug 23, 2026

Took about 20 minutes to swap out the stock piece and it clicked right into place on my GT-Line's rear bumper without any trimming. The direct fitment claim is spot on, and the finished look makes the back end feel way more aggressive than the factory setup.

I was honestly nervous about aftermarket diffusers, but this one surprised me—the direct fitment is spot-on for my 2022 GT-Line, no gaps or rattling at highway speeds. Only wish I'd grabbed it sooner since it's out of production now.
