I decided to take some pictures and describe what's involved in this process as I was installing it on my '17 SS 1LE. The idea is to create and extension for the front splitter and having wider fenders to eliminate/reduce air drag with the wider tires/wheels for track use.
Combined with the ZL1Addons rock guard, it will look as a one piece molding.
IMPORTANT: Please take your time and follow the below instructions and as always use this guideline at your own risk.
In this installation, I used the passenger side molding/flare, you will need to do the same for the driver side.
The OEM GM part numbers are below:
23315197, 23315196
NEW GM 2014-2016 CORVETTE Z06 FRONT WHEEL OPENING MOLDING SET
and with the tools below:
- Cordless drill
- T15 Torx bit
- 9/64" drill bit
- Good quality utility knife
- *Dremel tool (optional, this has been used to extend some of the holes on the fender flare, you may use a smaller drill bit with your cordless drill instead)
Remove these screws by using T15 Torx bit. We will need to remove a total of 4 screws, 1 at the very end of the fender line and 2 at the front (bottom and upper side of the brake duct hole) and 1 above the front screws that connects the extension on the plastic. The bottom screw in the first picture is where we will attach the folded tab. Before start anything, you might want to place this piece to get and idea and see how it will align
Drill through the hole when the this tab is folded
I slightly tightened the screw that goes through the folded/bottom tab and see how the others should align and
mark where I need to cut through this plastic molding so it doesn't block the air passage.
remove the screw behind this tab/extension and drill through that plastic so we can place the screw that goes over this.
With the bottom tab is tightened, extend the the upper screw hole with either dremel tool or cordless drill. I removed and placed the bottom/reference tab for alignment a few times back and forth to make sure everything is aligned.
See where I am going with this?
Be very careful and take your time when using utility knife to put a hole in this
All 3 front screws are now attached with the cut hole
align the plastic piece, mark and drill another hole with a drill bit here. This is the last screw that we'll be using.
Don't overtighten at this point as we will need to remove the adhesive tapes.
I decided to put the end of the plastic trim under the existing Rock guard. Since I used a small self-tapping screw to better secure the rock guard it will also help keeping the fender flare in place.
Notice the self-tapping screw in the middle of the rock guard.
You may now remove the double sided tape plastics and tighten the screws
I also trimmed the front side of the plastic trim to create more clearance for the tires. With about a 45 degree angle. Be very careful and don't ruin this plastic

Also slightly trimmed the rear portion so it is flush with the rock guard piece:
