When I change liners and then go to a track event I see the rubbing occurring. The holes don't appear until the second event after the liner wears through. Then the track turds start filling up the holes and impacting the modules mounted behind the liners. I get most of the wear on the driver's side. However, both the left and right side rear liners tend to wear more in the front than the rear of the liner. I think this could be reduced if I change my rear caster from +0.7 degrees to 0.0 degrees since that would move the lower balljoint slightly rearward.
I arrived at a similar conclusion, and set my rear caster back to 0 degrees a while ago. I honestly have not seen any significant difference between the settings at the track in terms of handling anyway.
We still need a solution. It's only a matter of time before a module gets destroyed, or the fuel filler hose. I have 4 new liners coated with truck bed. Haven't installed them yet. I'm thinking of coating the back side with fiberglass, or bondo.

Are you at factory ride height? I found out with my car that my times didn't improve when I lowered the car but the liners got worn out a lot faster. At factory ride height they last for more than 2 seasons. With it lowered they didn't last 2 weekends without holes.
My car is 100% stock Z07, with a nice alignment. We can talk about this all day, but we need a solution.
I called ACS to make plastic liners. 1 person calling ACS isn't going to make it happen. We need 10-20 people calling ACS.
Using a gallon of truck bed liner is just prolonging the agony.
I've gone through several liners in the rear this year.
Here's what I'm trying.
This side is towards the tire:
This side is on the other side of the liner towards the car:
My thinking is that the mesh will provide some structure so when holes form I can spay something like 3M rubberized undercoating to provide some coverage. I thought of putting the mesh facing the tire but I don't want to reduce the clearance there or have the tire fail due to rubbing against metal. My new stiffer springs should hopefully help with the rubbing.
If ACS made plastic wheel liners I'd buy them, though I don't think that's very likely since this isn't a problem unless you go to the track. They would never recover their spending on the plastic molds.
looks to me like you guys need stiffer springs or bump stops adjusted the tire should not be hitting the wheel wells, may be the suspension is set to low check ride height also.
I have coil overs from LG and my wear is from things thrown up from the track.

Well things "thrown up" causes massive damage on these cars due to having cloth. Once something is lodged, it just keeps getting bigger.
Anyway, changing the liners is pretty easy, so there's that : ))

This is a good approach, but instead of fiberglass, use Kevlar cloth preferably with epoxy adhesive. Don't use Bondo, it will simply chip away. I have not done this or had to do this to my car liners, but I have used Kevlar in the past (work applications) for applications where there is high abrasion of parts/surfaces due to multiple small projectile particles (aggregate impact). It works a lot better than fiberglass. A comparably thick Titanium sheet would also work but that is very cost prohibitive. A 50"x6 ft piece of Aramid (Kevlar) cloth is less than $120. This would be enough to cover all 4 corners behind each wheel with 2 layers. Put one or both layers on the side closest to the tire, if the tire is not physically rubbing the liner. If the tire is rubbing, the Kevlar could ware out the tire faster in the area it is rubbing, since the Kevlar is as strong as the carcass inside the tire. I have only used epoxy with Kevlar but you might be able to use the truck bed liner material as adhesive instead of epoxy. Kevlar is a little finnicky about what adhesive you use, epoxy works well though.
Looking forward to seeing the results. What is your objective? To protect the wheel liner from the tires or to protect the rest of the car when the regular wheel liner disintegrates and the internals would be exposed?

Also, what epoxy will you be using?
I already have a few "cuts" created by rubber pieces lodged into the wheel liner. I'm hoping to patch them up with this.
When not specified for application, I always use jd weld standard (not the weaker quick curing). I have ~10 packs of it in my toolbox.
Is there any way to reduce the friction of the tire with the wheel liner material so it doesn't wear out as much?
I am not sure if that is a possibility. Tens of thousands of pebbles, sand and dust particles get thrown at the wheel well, and they act line bead blasting. Even if we build the entire liner out of PTFE (Teflon), the particle blasting will eat away the material, and if the tire touches, it has a nice rough surfaces to eat into. Silicon compounds are some of the hardest in nature, so we can only prolong the inevitable. With Kevlar reinforcement, we considered a 3x life expectancy a very good result, most of the time it was in the 2x rage. The epoxy bonding agent will get blasted and the Kevlar would begin to fray/de-bond and finally break. We never found a permanent solution.
Seems I wore a hole in the Fender liner on the Left side
The photo shows the wear at the front of the liner half way down, there's a stiff cable or line inside which leads to a bulge in the liner.
That's where the wear is.
It's a fairly stock '19 Grand Sport, it is lowered on the the stock adjusters, 30K miles.
I do track it a few times a year but this is the first time seeing this damage, the right side has no wear.
Just wondering if this is common or am I seeing some wear in some of the suspension components.

Any thoughts appreciated
The easy answer would be to raise it to factory recommended ride height. If you don't want to do that there are multiple, more expensive, ways to help it. You'd have to stiffen up the suspension or put smaller tires on it for sure.
