The Version 3 HT Autos Bottom Line lip kit for the 2015-2021 WRX and STI consists of a front lip, side skirts and rear skirt extensions. Tough polyurethane construction has some flexibility, and resists dents and dings. Installation is straightforward, using existing body fasteners plus 3M double-sided adhesive; you will have to drill some 5mm and 6mm holes. For maximum security we suggest using some additional nuts and bolts to further secure the parts.

Five-piece kit includes front lip, left and right side skirts, and left and right rear aprons. The Version 3 kit has the latest 2018-style front lip and rear aprons, but it can also fit older 2015-2017 cars. 

Fits all 2015-2021 Subaru WRX and 2015-2022 WRX STI.
