Can I install each piece separately or does the whole kit need to go on at once?

Each of the four pieces is independent. You can install the front bumper, side skirts, and rear bumper in any order that works for your build schedule. No sequencing required — bolt them on as you finish prep and paint.

Do I need to sand and prime this before paint?

The kit Requires Surface Prep, meaning the surface is prepared for topcoat. Sand the panels lightly and apply your chosen primer and paint system according to your paint supplier's specifications. Standard automotive prep applies.

Will the side skirts interfere with jack points or ground clearance?

The side skirts are designed to clear factory jack point locations. Verify your jack points against the skirt profile before final installation. Ground clearance is comparable to factory side trim — no lowering suspension required.
