Well I confirmed that you can wear through liners with Continental ECF tires, which is an endurance 200tw. I'm not convinced its all due to rubbing under hard cornering - I don't doubt some rubbing is possible but I definitely have some holes that I'm pretty sure developed from repeated hits from debris and pieces of tire.
I have a new set of liners and I plan to brush on some epoxy coating after I install them in the areas where my prior liners have holes, and hope for the best. I was going to spray on bedliner but OP said that did not work and I'm not confident it would bond to the felt very well besides. I also thought of getting a roll of ~2mm
and making reinforced patches with that using a heat gun and rivnuts or something - but I'm afraid the material would just start tearing at the attachment holes, and besides forming the plastic close enough to avoid tire contact would be challenging I imagine.
I have some buddies that are into drifting and they make their own fender liners out of sheet aluminum or the abs i linked. They aren't very pretty but that is my last resort. These liners aren't cheap. My current set aren't too banged up, so I plan to try and use them as a set I can reinforce and experiment with off the car if the epoxy solution doesn't hold up.
I'd like to note here that I have since switched to C8 platform, and the liners have been holding up a lot better. Granted, I also switched to coilovers, but having little to no rub at all on a narrow body Z51 with 315/30/18, 345/35/18 is an accomplishment : )
Let's be clear. This is NOT from rubbing. This is from track debris & road debris going upwards through the liner. Happens to my S560 as well from highway driving. The liners are just garbage.
On my Z07, it's OEM sticky tires.

I'll say that it's both rubbing and debris depending on setup. I have aero and unfortunately the Z07 springs aren't up to the task when I crest and then come down on the other side of a rise in the track. My front liners clearly show 8" long rub marks and they have the typical debris shots as well. The rears are the same. .....6-8" long rub marks as well as holes that are clearly from debris shooting through them. I just keep patching with fiberglass screen stitched in with Zip ties and covered with spray on bedliner or flex seal. Once they're too far gone, they get replaced.
My 2013 Grand Sport had rub marks and debris holes in the plastic liners. My 1996 Grand Sport just had some debris holes.
The liners simply weren't designed for any sort of regular track use. I'm sure weight and cost played into Chevy's decisions, but I will also say that it seems like the liners could have been shaped a bit differently to help.
Even on casual track day you pick up a lot of rubber in them. I found the Mothers R3 Racing Rubber Remover 9224 works well for the stuck rubber.. obviously no point if your getting rubbing. My Z07 has had no rubbing problems as of yet. They really should have a racing version of them with more clearance and made out of plastic or carbon or something like that
I bought my GS used, So I don't know it's history.
While pulling rear wheels, looking for nails (it was cracks and nails), I found all the damage to this "compressed dryer lint" wheel well.
Since I'm fixing a half-dozen frustrating things that generate new cus words, I found this.
Take THIN Haircell ABS and make a patch until your budget will allow for a new set of compressed dryer lint.
The ABS is thin enough to cut with a big pair of scissors and strong hands. Trim to fit, tuck it in behind.

Curious...what are you using to glue it to the back or are you riveting?
Since it's temporary, I used a couple of squares of 3M emblem tape. There was nowhere to screw that particular piece into
On the other patches, I used a speed nut and 8MM screw.

Amazon shows the product comes in various thicknesses. When you say THIN how thin do you mean? I suspect it isn't 1/4 inch or 3/16 but are you going with 3/32 or 1/16?
Does anyone have a part number for the passenger side rear ? Just ran over a piece of metal and destroyed the tire and liner .
Talk to your dealer parts dept (walk in don't call on the phone unless you are a regular parts Customer). They will probably be the lowest-cost supplier for the part. Ask the parts department if they have a better price than what they quote you. I usually get a price that is somewhat higher than the online parts suppliers but don't have to pay the high shipping cost since the dealer price already includes shipping. With the online suppliers the shipping from GM to them is in the cost of the part but the shipping from them to you is on you.
I'm not sure what you mean by ABS reinforced liners - if you mean the guy from a few posts above, I'm confident that will not hold up on track. If that patch is held up with 3M anyway. No way that will last on track. Of course he did say it was temporary. Maybe if it were attached with Rivnuts.
Yes, I was referring to the previously mentioned use of 1/16" ABS plastic. If the material held up then I imagine one could find a method of attaching it that worked. Not just patching a hole but covering a wider area in advance. I'm going to be installing a brand new set soon and would like to reinforce them prior to installation.
This is also a product I've looked at - i know that people in the drifting community use this for fender liners. I think the challenge would obviously be forming/attaching to existing liners in such a way that doesnt allow tire rubbing. And, even if the patch is strong, the patch could just rip at the attachment points. The original OP of this thread said spray on bedliner didn't work, but I didn't try it.
Yeah if it doesn’t flex easy it may be hard to keep clearance. I wonder if anyone has actually tried the Kevlar fabric idea. Wonder if that could be molded and bonded to the liner better with some sort of epoxy.
What have people done to try and preserve their liners. I have 2 track weekends (3 days each) at VIR and WGI and this is what I got out of my rear left wheel well. I replaced these at the end of last season and have big holes again. I sprayed them with track bed liner but that clearly did not help much. So I’m trying to high tech route with some wire fence, zip ties and duct tape (everyone a car goes faster with duct tape ). Curious what other people have done. I’m running Pirelli scrubs on the track.
