Skid plates?

[SoundAutomotiveGroup]

Anyway to install them without drilling into the bumper?

Though I wouldn't suggest it I've seen installations with two sided tape.

Neither the Huracan nor the Aventador have any factory mounting locations at the nose that can be utilized when mounting the Skid Plates.

The mounting hardware does add strength but I suppose if you could find a way to hold the Skid Plates tightly in its proper position long enough for the adhesive to set it would hold. You'd probably have to let the car sit for a good 48 hours to let the adhesive cure.

Keep in mind when using screws the area around the hole gets compressed and can leave a little bump. By using the rivets supplied the hole needed is very small (3/16s) and by nature of the fastener doesn't expand outward compressing the bumper and leaving a bump. Instead in it pulls down sandwiching the bumper between the Skid Plate and itself. If removed would leave a smooth and clean surface.

All that being said, in all the years I've been doing this I can't remember a client ever wanting to remove a set.
