Do these fenders require factory mounting point alignment?

Yes. Before installation, verify that your vehicle's existing mounting locations match the panel hole placement. Compare hole spacing on the fenders to your OEM reference points to ensure proper fitment and panel gaps.

What prep work is needed before painting?

Sand and prep the surface with your choice of grit and method to achieve proper adhesion for your topcoat. Use a quality primer and paint system designed for plastic substrates to ensure long-term durability.

Will these fit with wider wheel and tire setups?

The 30mm extension provides additional clearance over the stock quarter panel. Verify tire diameter and offset against the new fender profile to confirm tire-to-panel clearance for your specific wheel and suspension setup.
