2015 - 2021 McLaren 600lt 540C 570S BKSS Style Cabon Fiber Side Skirts Under Board

Enhance the side profile of your McLaren Sports Series with these BKSS Style carbon fiber side skirt under boards. Designed for the P13 platform, this exterior upgrade creates a lower and more aggressive appearance while complementing the vehicle’s sculpted factory body lines.

The streamlined BKSS Style design adds greater visual definition along the rocker panels and gives the McLaren a more purposeful, race-inspired stance. Their extended under-board profile enhances aerodynamic presence and pairs naturally with compatible front lips, rear diffusers, spoilers, and other exterior upgrades.

Crafted from carbon fiber, these side skirt under boards combine lightweight construction with premium exterior styling. Designed for compatible 2015-2021 McLaren 540C and 570S models and 2018-2021 McLaren 600LT models, each package includes one pair of BKSS Style carbon fiber side skirts.
