Will this lip reduce my ground clearance?

The lip extends downward from the bumper line, so you'll have minimal additional clearance loss. Measure your current setup and account for the lip profile before aggressive approach angles or very low suspension setups.

What's the difference between FRP and urethane for front lips?

FRP is rigid and maintains its shape under normal driving. It's lighter and easier to finish than heavier composite materials, making it ideal for bolt-on aero pieces that see moderate airflow loads.

Do I need to drill new holes or can I use the factory attachment points?

This lip is designed around factory mounting locations. Verify the bumper mounting holes on your vehicle align with the lip before assembly, then secure according to your vehicle's fastener specification.
