Does this wing use the factory mounting hole pattern?

The RBS wing mounts at the stock anchor points on the trunk lid. Before installation, verify your vehicle's mounting surface is clean and free of rust or debris. If you're adapting to an aftermarket trunk, reference your new lid's mounting hole locations to ensure alignment.

Will this wing cause trunk lid interference when closing?

The RBS profile is engineered to clear the trunk lid seal. With proper mounting at factory points, you'll have full closure. If you've modified your trunk structure or latch, measure the gap between the wing endplates and your lid edge before final fastening.

What prep is needed before painting?

Sand the entire surface with medium-grit sandpaper and wipe down with a tack cloth to remove dust. Your chosen primer system will bond best to a clean, slightly abraded FRP surface. Follow your primer manufacturer's instructions for dry time before topcoat.
