Installed these guards and they seem to be made of good quality material though the supplied 3M tape is garbage. Front guards went on without any issues. Rear guards need to have (4) 8mm holes drilled into the rear apron which will require the rear wheels to be removed to gain access unless you have a 90 degree angled drill adapter. Fit is perfectly fine with no need to trim any of the guards for an aligned fitment.
Half the cost of OEM (which are made in China as well) and look as good as what I assume OEM looks like. Solid construction, fits my C7 perfectly and look great. Just enough to be different but not enough to look out of place. You’d never know they aren’t stock.
These splash guards are of good quality material. Matches with the stock c6 diffuser perfectly. Fitment is very good but not 100% if you want to nit pick. I think it's acceptable, and I'm particular about my cars. The tape is absolute trash, peel that off and throw it away.

The front splash guards are very easy. Used a rivet tool to remove the fasteners and just plugged them back in with the splash guards. Did not bother with the fasteners that came with the guards. Easy as pie and very secure.
The rear requires drilling of 4 holes in the plastic parts of the fender wells, which is great because there's no way I would drill into the painted parts of a Corvette wheel well, or any car for that matter.
You DO NOT have to remove the wheels if you use a 90 degree angle drill attachment. I picked one up for like 15 bucks. No big deal, and it will be useful for future projects as well. I also opted to use screws with lock washers instead of the supplied fasteners for the rear splash guards because there's not enough room to get your hand in there and push those push pins in with the wheels still on. My goal was to get them on without removing the wheels at all costs. Took about 1 hour, and I think they look great.
My recommendation is to get them, especially if you drive your Vette every day, rain or shine. The only very minor gripe is the fitment, but it's passable. They're just splash guards and they seem to do what they say they do.
