Undertrey and wheel well covers to be replaced

I've converted my 06 RX8 into a rally car last year and the front bumper and undertray keeps getting a little damaged. I am looking for more robust alternatives to the undertray and that small strip of gray plastic that connects the undertray to the front bumper itself. I know I can just replace these or repair them (it isn't hard or expensive), but does anyone make a stronger alternative? Constantly doing it is carving into drive time.

Otherwise, can someone help me confirm the part numbers of the passenger side front wheel well fender cover (that part that covers the oil cooler) and the small strip of plastic that holds the undertray to the bumper (the part that contains the "rotary" triangle pictured). I think that plastic strip is F151-50-0K0C, and the front wheel fender cover is F151-56-13YB. Do you know what those screws and the metal clips are called?

There are ruts that form during rally events, but where we practice at home we have bushes that catch the car if you run outside a good line. The ruts are getting to the tray. But my son is the one hitting bushes that lead to the missing wheel well part.

The screws and metal clips are going to be a bitch to find OEM.

I use clipsandfasteners.com and I can find some ones that are similar.

thank you, mangoMikey
Thank you for the information on the metal and plastic screws. The ones I need for my rear panel after replacing the rear tail light gaskets they’re on their way. Thank you for the information – Sparky 56.

For what you are looking to do with the car off-road you may need to make some custom stuff that’s more recessed for clearance purposes. I race north east dirt modifieds we use Zeus springs and buttons to keep our tin and plastic panels together. Here’s a link to one of the suppliers panel fast we use and the products. Again with what your asking the suspension to do with travel it’s going to require more clearance or custom body to work so you don’t have to worry about the front end coming apart.
