Ellie ★★★★★

Installed this kit in my 2018 WRX over the weekend, and the climate control knobs click with a satisfying precision that makes the stock plastic feel like a toy. The e-brake handle is a nice weight too, completely changes the look of the center console.

Adam F. ★★★★★

The billet aluminum feels incredibly solid in hand, and the e-brake handle alone makes the cabin feel like a proper performance car. The climate knobs click with a satisfying, precise resistance that the stock plastic never had.

Ryan ★★★★★

Installed everything this afternoon and the billet aluminum knobs have a satisfying heft that makes adjusting the climate controls feel premium. The e-brake handle fits perfectly with no slop, really ties the interior together.
