Will this reduce my ground clearance or scrape on driveways?

Ground clearance loss is minimal since the lip mounts flush to the existing bumper structure. Check your driveway angle and any steep approach angles on your route — if your factory bumper clears, this lip will too. If you frequently bottom out, measure the extension height before final mounting.

Is FRP rigid or does it flex in impacts?

FRP is a hard panel construction with some flex under stress, which helps absorb light impacts without cracking. It won't bend permanently like plastic, but it's not rigid steel either — it's engineered for the balance between weight savings and durability. Avoid contact with curbs and parking lot obstacles.

What prep does this need before painting?

Sand and prep the surface with appropriate grit before applying your chosen primer and paint. A clear coat finish after base color is recommended to protect against UV and road debris. Follow your paint supplier's guidelines for FRP substrate prep.
