What base wing does this attach to?

This add-on is engineered to mount to Z-28 or ZL1 style factory wings. Verify your vehicle uses one of these assemblies before ordering. You will supply the base wing separately.

Will this add-on interfere with the trunk lid?

Since this is a bolt-on extension to an existing wing, final clearance depends on your wing's existing mounting height and angle. Before installation, mock-fit the assembly to confirm trunk operation remains unobstructed.

What prep and finish should I apply?

Sand and prep the FRP surface thoroughly before applying your chosen primer and paint. The add-on ships raw and unsealed — proper surface preparation ensures adhesion and durability of your topcoat.
