Will these interfere with my floor jack or jack points?

No. These skirts bolt to the lower rocker panel and sit below factory jack point access. Your stock lift points remain fully accessible.

How much ground clearance do I lose with these installed?

These follow the factory rocker line and add minimal depth. You won't notice any clearance reduction on street driving. High-speed ramp entry remains the same as stock.

What's the advantage of FRP over adhesive-only skirts?

FRP bolt-on construction means no permanent damage if you need to remove them later. The material also absorbs minor road debris impacts without cracking, where glued-on plastic tends to fracture at stress points.
