Jason W. ★★★★★ Oct 20, 2026

I was skeptical about how well these would stay on, but the precision-engineered fit is spot on—they clicked right into place on my 2016 WRX with no gaps. The aggressive styling really completes the look without being over the top.

John ★★★★★ Oct 19, 2026

The fit on my 2015 STI is absolutely perfect—they clip right into the window channel with no gaps or rattling. I can finally crack the windows in the rain without getting soaked, and the aggressive look matches the car’s lines way better than the cheap stick-on ones I tried before.

I was a bit skeptical about how much airflow these would actually let in, but the fit is spot-on and the aggressive styling really transforms the look of the car. They cut down on rain noise too, which I didn't expect.
