Do wheel well liners serve any purpose on a track car?
I'm planning to install front brake cooling ducting on my track-focused 968, and the plastic wheel well liners are right in the path from the duct scoops in the bumper cover and the brakes I've replaced the pop-up headlights with fixed, so there isn't much else between the scoops and the brakes. So, I either need to cut holes in the liners to allow the ducting to pass through, or get rid of the liners altogether. Is there any harm in getting rid of them? It seems that all they do is trap heat from the brakes, and they get in the way of enough projects to be an annoyance. I only drive the car on the street to and from the track, and I never drive it in the rain. Am I overlooking some vital function of these things? Thanks.

Main purpose is to keep dirt away so you dont need them. However on the passenger side were the ABS unit is Porsche kept the back half of the liner on the 944 Turbo Cup cars to protect it from damage from flying debris. Also you will have to accept getting small dents from the inside and out on the fenders from rubber and stones thrown from the tires together with more noise.
The 968 RS cars had them but with guides for brake cooling.
Good luck

I keep them because at the rear, with them off, it's basically an air capture parachute back there.
New car, spacing fenders out 1.5" to meet maximum allowable width (combined with reconfigured wheels) for SP3 class, so with fender now vented at rear along the door, liners are going.

Thanks for the responses. I hadn't thought about the potential for dents from underneath. I think I'll keep them, and just cut holes for the brake ducting. Everything is very accessible with the bumper cover off, especially since I got rid of my pop-up headlight.

Bob, with TWS closed, where are you racing mainly...?
That's the only place I remember ever seeing you/your car.
We haven't been to COTA in the last few years or Hallet in the last 2 but I suspect one of those...?
You should come to NOLA.
944s rule the esses section.
