I don't have a Quick Jack and didn't know if THAT was my only alternative or not.
No, but with jack pads and enough floor jacks you could still raise the car. The biggest issue I run into with this though, is now the car is raised and there's no where left to put a jack stand.
I purchased:
2 PITTSBURGH AUTOMOTIVE 1.5 Ton Aluminum Rapid Pump Racing Floor Jacks (when on sale for $59.99 each @ Harbor Freight).
4 Dewhel Jack Pads Billet Anodized Aluminum, Red ($39.99 set @ Amazon)
I made:
4 wooden boxes to place under front or rear or all four tires for safety.
Currently I'm able to lift the complete front or rear end of my C4 by locating a floor jack in the center of the front or rear. I'm guessing this won't be possible with the C8 because: 1) I don't know of any good central lift points and 2) even if there are, belly pans would have to be removed to access them and how would you get those off while the car is still on the ground. Am I missing something here or is that just not going to be possible?

No way could I get even my long reach jack under my C7 centers. My MO is to use Jack Pads and two jacks from the sides and then jack stands. BUT as you note, to use jack stands on a inside frame would require removal of the aero panels. My plan (as soon as I get the C8 home after it arrives at my local Courtesy Delivery Dealer) is to change brake pads (so I don't have to clean the rotors (did that with my current 2017 Grand Sport.)
I'll probably only lift one end at a time and place a jack stand under the exposed "A" frame. Will keep some tension on the jack for security. When I change oil in the C7, this pic shows my MO. I won't use jack stands on both ends of the car so support the rear wheels on Stanchions to get the car level. Below is a pic I made on Jacking the C8.
Bump again...... Will anyone with a C8 please take a few measurements, please? I am seeking to purchase a Quick Jack that I can use on both the C8 and our '17 Honda Pilot. I am leaning towards the BL 7000 EXT which has a 66" max spread on the lifting points. But it is also 76" long so I need to know that it will slide in between the tires on the C8.
1. Distance between the 2 oval lifting points at the widest ends of the ovals. I realize Jerry has already posted calculated measurements, but I would prefer an actual measurement, please.
2. Distance between the tires. please hold the tape measure about 3 inches off the ground and specify that measurement.
Also, one of the first projects would be to install my 5VM Aftermarket C7 Carbon side skirts and front splitter. The side skirts obviously attach to the rockers..... Would the QuickJack lift be in the way of the rockers??? I would need access to that area to install the side skirts. I'm hoping that someone with their C8 already can look under to see if the lifting locations are far enough inboard from the edge of the car to allow for side skirt installation to the bottom of the rockers.
Lastly, does anyone know what the distance between the tires is, front to rear? QuickJack says to measure the distance between your front and rear tire treads, keeping the measuring tape 3" above the ground.
Below is my standard-size, Quickjack BX5000. As you can see it comes with different height lifting blocks and lays flat. There is a lot of room to maneuver the blocks to fit the lifting points. If it doesn't work in one direction you can turn each jack 180º, which I've had to do to lift my C7 vs. our MX5 or 718.
I can't imagine it will interfere with side skirts. The defining issue is here length between the tires.
Thanks Foosh....... just trying to see if I can get one lift 7000 EXT to work for both the C8 and Honda Pilot. The Pilot weighs 5800 lbs so would need the BL 7000 model as well as the EXT longer one as the lift points are about 64" apart on that vehicle. Need measurement between tires on a C8 to determine if it will fit a C8 too.
I'm hoping that with the lifting points somewhat inboard on the frame that it allows enough room to get in and install side skirts as that will be one of my early projects.
Based on the photo measurements, the jacking pucks installed in the oval slots will be "mostly" on the rubber blocks if they are positioned at the very end of each lifting area on the QJ5000. That is why I am trying to get actual measurements from an actual C8. I know they will fit if I slide them under the car, but then the locking brace will be in the middle under the car and not safe to get it to lock in place.
Understand the thought that Quick Jacks are a safe way to jack up the C8 - BUT so are other safe methods!
I plan on installing low dust ceramic pads as soon as I get my C8 Z51 home (as I did on my current Grand Sport.) I'll do one wheel at a time, use a 1 inch high Jack Pad and one of my jacks to remove the wheel. I'll use a Jack Stand under that lower "A" arm for security (keeping some tension on the hydatic jack.)
But the next thing I'll need to lift the car for is installing the "C7 Carbon" Side Skirts I have on order. A Quick Jack would be in the way. I plan on using my two wood stanchions on one side of the car as I need access to the area where the jack pad and jack are located. So, use a Jack Pad and Jack, insert both stanchions under that side front and rear wheel. Very secure. I have normally use the stanchions under the rear tires and jack stands in the front of my C7 to change oil.
Pic of the Install of Full Length Side Skirts On My 2014 Z51. Masking Tape Was Marked on Where to Drill for Rivets
So you and I are doing the exact same thing in short order........ swapping out brake pads and installing C7 Carbon Side Skirts. I installed C7 Carbon GTX set on my '16 Stingray and then when GM Engineering bought the car back, I removed them and put them on my replacement '17 GS. I've ordered the Bundle Pack 2 in Carbon Fiber from C7 Carbon back in April.
So, I was considering buying a Quick Jack 7000 EXT for those tasks as well as wheel removal for ceramic coating, as well as using it for our '17 Honda Pilot.
I was afraid someone would say that the Quick Jack would be in the way of installing the side skirts....... I've read through the factory installation instructions and having to access the underside of the rocker panels to drill and rivet the skirts on was my concern with a QJ, I did watch a video of installation of another carbon fiber vendor's side skirts and he used a center scissor jack that had arms that extended out and articulated in any direction for each of the 4 corners to pick up the lifting points. Seeing that video was got me looking......... one of those single, center designed low rise scissor jacks would be preferred, but they are much heavier, more expensive, and bulky to deal with.
Anyone have experience with a low rise single center scissor lift ???
^^^ True for the C8, but as i've mentioned a few times, I'm wanting 1 lift for both our C8 and Honda Pilot. I need the 7000 capacity as well as the 66" reach.
Just wanting to verify that it will fit between the tires on the C8, which after doing calculations it will, but I was hoping someone would actually put a tape measure on it as well.
C8 spacing for the lift points (oval shaped holes).
Quick Jack SLX models will reach out 60". EXT models go to 66".
Do you own a C8 that you did these measurements? from post #2 measurements from a photo showed 59" to the centerline which would be 61.5"+ from the outer edge of each of the jacking pucks inserted in those oval holes. I measured my QJ5000 and the spacing to the outer edges of the rubber blocks is 59.5" so the rubber blocks would contact the jacking pucks but only partially - not safely.

The 55" value is from a post made from an actual measurement made early this year.
The 59.5" measurement is from a photogrammetric measurement (scaling from a photograph).

If that is the case, then the QJ5000 should work fine on the C8 with the jacking pucks installed.
