Will the lower valance clear my splitter or undertray?

The R34 design extends slightly lower than stock. Before install, verify clearance between the bumper's lower edge and any aftermarket splitters, air dams, or undertray components on your vehicle. Grind or trim the valance lip as needed to avoid contact at full compression.

Do I need to modify anything to fit this on my chassis?

This bumper is optimized for vehicles with newer-generation headlight and bumper bar geometry. Older setups may require modification to hood gaps, headlight surrounds, or mounting points. Test-fit before committing to paint, and reference your OEM service manual for mounting hole locations if you're adapting it to a custom configuration.

What prep work is needed before painting?

Sand the primer surface lightly to open the grain and remove any surface dust or handling marks. Wipe clean with a lint-free cloth and tack rag. Apply your chosen primer or base coat per paint manufacturer specs. FRP accepts all standard automotive finishes—no special sealers required.
