Do I need to modify the fog light holes or sensor cutouts?

Check your vehicle's OEM bumper for existing sensor and light openings before installation. If your setup includes factory sensors, reference those hole locations and mark them on the new bumper before final fitment. The FRP can be carefully drilled or routed to match your specific configuration.

Will this bumper clear my trailer hitch or diffuser?

Measure the clearance between your current hitch/diffuser and the OEM bumper. The I-Spec profile matches factory geometry, so your existing clearances will remain the same. If you've added aftermarket components, test-fit the bumper before final installation to verify alignment.

What prep work is required before painting?

Sand and prep the surface thoroughly before applying your chosen primer and topcoat. FRP typically requires a light scuff and wipe-down to ensure proper adhesion. Use a quality automotive paint system suited to plastic substrates for best results and durability.
