Will these panels interfere with factory jack points?

No. The F-1 profile maintains clearance for stock jack points. Verify your specific jack location before installation, but rocker geometry is designed around OEM suspension access.

What's the difference between FRP and urethane for side skirts?

FRP is more rigid and resists impact damage from road debris and curbs better than flexible urethane. The trade-off is less flex — ideal for a fixed rocker panel. Urethane is better for applications where flex is an advantage.

Do these panels come with mounting hardware?

Hardware is not included. You'll need stainless fasteners (bolts, washers, and clips) to secure the panels to the rocker and factory mounting points. Use corrosion-resistant hardware to prevent rust staining on the FRP.
