Customer Reviews (4.4 / 5 · 5 reviews)

Ellie A. ★★★★★

Bolted these on over the weekend and the direct fitment for my 2020 Si was spot on—no drilling or guesswork. They tuck in tight along the rocker and give the coupe a lower, meaner stance that catches the light just right.

William ★★★★★

The aggressive styling is exactly what I wanted for my 10th-gen build, and the direct fitment meant zero guesswork during install. They hug the rocker panels perfectly and really complete the lower body line.

James ★★★★★

Swapped out the factory plastic for these side skirt extensions, and the direct fitment made installation a breeze. They really tighten up the coupe's stance without looking overdone.
