Can I install all four pieces at once, or should I do them separately?

All four pieces bolt independently to factory mounting points. Install front splitter first, then rear diffuser, then side skirts last—this order prevents fitment interference. You can paint them as individual panels or assembled; raw FRP condition lets you choose your workflow.

Do I need to use gap filler or seam tape between the panels and my OEM bumpers?

Designed for tight factory mounting tolerances. Minor gaps at seams are normal and easily sealed with flexible adhesive sealant or gap filler after painting. Test fit all pieces before primer application to confirm alignment with your vehicle's mounting holes.

What prep work is required before painting?

Sand all surfaces with appropriate grit to ensure paint adhesion, then wipe clean and apply your chosen primer and topcoat system. FRP bonds well with polyurethane and acrylic urethane finishes. Ensure proper surface prep—this is critical to paint longevity on FRP.
