Show original supplier description

The STILLEN side skirts are precision-engineered rocker panels designed specifically to enhance the aesthetic flow and lines of the 2014-2017 Infiniti Q50. The set includes both driver and passenger side panels, featuring a matte black finish that arrives ready for further prep and paint if desired. These side skirts serve as an excellent complement to front splitters and rear diffusers for a cohesive, upgraded look. Installation of this product is straightforward, but it is essential to verify fitment for your specific Q50 trim level, as they are compatible with 2014-2017 Infiniti Q50 AWD and RWD models. As these are aftermarket body components, they should be test-fitted before any permanent modifications or paint work are performed to ensure satisfaction with the final alignment.
