Do I need to modify these for my Z06?

Minor modifications are required for Z06 fitment. Verify your specific model's rear panel geometry before final installation to ensure clean gaps.

What prep work is needed before painting?

Sand and prep the primer surface according to your chosen paint system's requirements. Work with your painter or paint supplier to confirm grit sequence and primer compatibility for best results.

How do these affect wheel clearance?

Over-fenders extend the body line outward to accommodate wider wheel and tire setups. Verify your suspension geometry and tire size against the fender extension to confirm adequate clearance for your build.
