Will this change my ground clearance?

The grid lip adds minimal extension to the lower fascia and does not significantly reduce ground clearance. Verify your approach angle on speed bumps and steep driveways — extension depth varies based on fitment design. Drive carefully over obstacles until you're familiar with your new profile.

Is FRP rigid or does it flex?

FRP is a semi-rigid material that offers balanced flex and durability. It won't shatter like brittle resin but maintains structural integrity better than soft urethane. Minor contact won't crack it, though impact at speed can cause stress marks. Inspect regularly and touch up any stress areas before primer deteriorates.

What prep work is needed before painting?

Sand the surface with appropriate automotive grit to promote paint adhesion, then clean away all dust. Apply your chosen automotive primer and topcoat according to paint manufacturer specifications. FRP absorbs moisture, so proper sealing prevents long-term edge delamination.
