Will this wing interfere with my trunk lid?

The grid-pattern rear wing mounts to the trunk lid structure itself. Before installation, verify clearance with your trunk mechanism fully open and closed. If you're running an aftermarket trunk or have modified the rear panel, confirm the mounting points on your specific setup align with the wing's hole pattern.

What should I use to finish the carbon fiber?

Sand and prep the surface to your desired smoothness, then apply your chosen primer and paint or clear coat. Carbon fiber benefits from a UV-protective clear coat to preserve the weave pattern and prevent oxidation over time. Your local automotive paint supplier can recommend products matched to your color and application method.

How stable is a three-piece wing at highway speeds?

Three-piece designs distribute load across multiple mounting points, which improves rigidity when properly secured. After installation, verify all fasteners are tight and check them periodically during the first few weeks of driving. Confirm mounting hole alignment and fastener engagement are solid before extended highway use.
