Trunk pop up height.
Just curious as to how high other c5 trunk lids pop up when you activate the release switch. Mine is always about 1/2 in. A little higher and I could get my big fingers under the lid a lot easier. Any adjustment techniques?

Trunk Popper for a Vert or Z06
This is an easy mod but for those of you who prefer to buy the ready made item it sells for a very reasonable price of $15.95 from one of the Forum vendors. Unfortunately the vendor doesn’t ship overseas so I needed a DIY version:
If you want to try yourself, pick up a 7/8” compression spring from Home Depot. They retail at $3.98 for a pack of 4 springs, 2 large and 2 small. You’ll also need an end cap of the same diameter. I used a 7/8” rubber stopper ($1.76). The advantage is that it acts as a soft buffer and can be trimmed to fit.
Cut the large spring to a length of 2”. The springs are quite strong so it takes a bit of elbow grease to cut it. Tighten the radius at the cut end of the spring to give a hole to fasten the screw through.
Undo the T30 torx screw on the right hand side of the closure plate. Insert the torx screw down the barrel of the spring and retighten it in place.
Slot the bung in place. You can trim the bung to get whatever fit you prefer. With it as shown it takes a good push to close the trunk. Trimming the bung will make it easier to close..
It took 10 minutes and all the lubrication and fiddling with the lock are a thing of the past.

Mine, when I originally purchased, only popped up about 1/2 inch. I just lubed inside the latch with silicone spray. Now it pops up a full inch. More than enough room to get my fingers in.

The top of my hatch raises up an inch above the rear fascia, which gives me a gap of a little more than 3/4" to get my fingers in to raise the hatch. Plenty of space for me.

I have used silicone spray on the piston rods, hinges everywhere but inside the latch. I was ready to order the spring assist today, but sprayed the latch assembly with silicone this morning and lo & behold it's popping about at least an inch now. Plenty of room to get my fingers in there now. When this no longer works I know about the spring kit. Thanks so much to all.
