Will these skirts block access to the jack points?

No. The GP-1 design is positioned to clear factory jack point locations on the rocker. Verify your specific vehicle's jack point height before installation, but these panels are engineered to sit above standard lifting areas.

Do these skirts sit lower than stock rockers and increase ground clearance risk?

These panels replace the rocker area with a deeper profile that may extend lower depending on mounting height. Check ground clearance on speed bumps and steep driveways before final installation, especially if your vehicle is lowered.

How susceptible is FRP to road debris damage?

FRP is durable but not impact-proof. Stones and road debris can chip or crack the material, especially on long drives. Paint protection or a clear protective film on the lower edges will extend the lifespan of the finish.
