I keep bashing out the front composite undertray, any tips on attaching it better?

I know the OEM composite undertray is known for being brittle, but I don't think I've been mounting the corners properly.

I've had the original holes tear with the clip on them. Is there a good fix for keeping the original mount points once the clip hole tears?

As a stop gap, I've used the PO's drill hole to screw directly into the material but I'm not sure it's a permanent fix.

Get a Turner or MPorium aluminum tray. Buy OEM replacement from FCPEuro to take advantage of guarantee. Outside that, drive more carefully, hit bumps from an angle slowly.
