I know that jacking up a C8 has been covered in many searches online. I have a lift bar to raise for Porsche 911 that I made out of rectangular aluminum bar. I have included a link on how this works on a Porche. What do you think for a C8? I permanently attached pucks on the bar at the proper spacing.
I actually just made one out of 1-1/2 square 1/8 thickness steel tubing. I drilled through some hockey pucks and attached them with 5/16 bolts with about 1 inch sticking out the top of these to use as locating pins.
It works great.

With my 911 Turbo which was weight biased to the rear of course, I would place the floor jacks closer to the rear jacking point. Worked fine. As a reminder I put the car on Race ramps to get the car higher. Once I set this up for the C8, I will post some pictures and possibly a video.
You can lift one side of the car if you use the transport hole forward of the official rear lifting location. Be sure to use a puck with a locating feature if you do this. The front tire will leave the ground after the rear tire is about an inch off the ground.

I used to have a C7 and it would fit onto my lift. But the C8 has a greater distance between the lifting pucks so I had to make something that I could use to lift my car. I have let it sitting on the lift overnight with no issues. I see the bar does bend about 1/8 inch in the middle.

Could you (or someone) explain this to the uninitiated? What is a puck with a locating feature? I have always used ramps, but I now need to get wheels off, so I am trying to figure out how to lift the car. It makes me nervous to attempt to jack the car at points where GM says not to jack the car. I don't want to make any expensive mistakes.
I saw this in another post from you, but I don't know what it means:
"The reason these transport holes aren't recommended for lifting is they could cause a car to fall off a 2 post lift. However they appear to be structurally adequate for lifting with jacks. One important point is to make sure you are using a lifting puck between the jack and car. And make sure the puck has a locating feature that goes into the hole to prevent it from slipping. You may have to grind off one side of the "T" to get it to fit into the hole."
Could you please elaborate? What is the T that needs to be grinded off?

It goes between the jack and the car. The locating feature I'm talking about in this case is the T which normally goes into the oblong lifting hole in the car and then turned 1/4 turn to keep it from falling out. The locating feature (T in this case) prevents the puck from slipping off the frame during use. Some people make their own from hockey pucks. Some pucks can be permanently attached to the car. If you want to use a puck with a T in other locations the T may be too big to fit through the hole so it needs to be shortened enough to fit through the hole.

Ok got it. Thanks for the explanation. The pucks at that link do not say that they are compatible with a C8, but one of the reviews said that they are. Do you think those are about the right height for the C8, understanding that the T may need to be grinded down to fit?
Also, regarding jack stands, I would guess that I need to get ones that are relatively flat on top such as
. Does that sound right, or do you have a better recommendation for jack stands?
I am thinking about jackpoint jackstands but they seem inordinately expensive for what they do, and Rennstands seem to be out of business, as every single item on their product page is listed as out of stock..
Sorry to hijack this thread but I think that it had run its course anyway.

Also, regarding jack stands, I would guess that I need to get ones that are relatively flat on top such as Escos (not sure there is room for those and the jack) or maybe these with small wings, so as to fit the puck, and not ones that are more cupped and designed to support an arm or a bar like these. Does that sound right, or do you have a better recommendation for jack stands?

Several ways to use jacks and jack stands.
Pics show what member Big Lebowski used to remove front calipers on C8.
How I jacked up my E-Ray to remove rear wheel. Need a narrow base jack stand. I used one that cost only ~$10 compared to the more expensive one shown above. Put the Jack Stand close to oval lift slot with jack pad/jack and C8 won't Tip!

I don't think there is much of a difference in the rubber pucks but you can do a search and find some that specifically say they fit a C8 but the ones in the link would probably work. You want to make sure that they are not so large that they overlap onto the SMC rocker panel. You need to have enough pucks both for the jack stands and the jack.
I just regular jack stands but you do need to be careful to get the puck centered correctly. The ones with a round top would probably work the best but I haven't had any problems with the other types other than they tend to chew into the pucks. You do need to be careful about the base not being so large that it interferes with the jack but, again, I haven't had any problems with just regular jack stands (I don't remember my brands).
Maybe someone else will chime in about their experiences.
Ok, thanks RKCRLR and JerryU. That all makes sense to me. I like the idea of using some kind of regular jack stands. Those are easier to justify than almost $500 for a pair of 2-ton Jackpoint stands with a fixed height. Regular jack stands can be had with flexible height options and varying weight capacities, all for a lot less money. You can get 3-ton regular jack stands for less than the price of a set of steel block plates for the Jackpoints (might need different plates for different cars).
I have my eye on a low profile aluminum/steel jack. Once I get that, I'll put it in position under my Eray and see how much horizontal room I have for the jack stands, and then I'll buy appropriate jack stands and pucks. I appreciate the guidance.

As noted, in my Pics above best to have jack pads with Tee that fits the Vette's oval lift slots. Especially with a short lift race type hydraulic lift as the jack MUST move in as it is raised. If it doesn't, the jack saddle can pull a flat "hocky puck" off the frame. With the Tee top AND a recess in the jack saddle that will help pull the jack into the car.
Second, I did not use a pad for my jack stands placed close to the jack on the frame. I use plastic pads on the metal jack stand top. Protects the frame. I mounted jack stand closer to the jack saddle/pad than where the round hole is located.

The shorter the lift arm, the more the jack MUST move in or the jack saddle could slip off the jack puck. Or if a jack pad without top Tee that fits in the frame oval slot is used it can slip off with jack saddle.
A jack pads with Tee top that fits the oval frame slot AND a jack saddle that has recess with sides it can help pull the jack into the car center as is required. Note, my large, long arm jack was NOT pulling into the car center because the jack saddle was flat. I welded a 5/8 inch high rim to the jack saddle. It helps pull the jack into the car with a 1 inch high jack pad having a top Tee that fits the Vette frame oval slot.

JerryU, why not use the round holes for the jack stands?
Using 2 floor jacks, starting at the rear, jack one side up using the puck location. When the car is up as much as you want, put second floor jack just ahead at the tie point, remove first jack and put jack stand under puck. Repeat on the other 3 corners. When done, put the floor jacks on each side at the rear as back up.

I put the jack stand as close to the Jack, jack saddle, Jack puck in the oval slot in the fame. Had no need for a Jack Pad for the Jack Stand as I use the plastic pads.
Pic without plastic pad. Pic with Jack Stand pad. Used those for years. Had used those Jack Stand pads for years. Fit my many pairs of Jack Stands. Note on my C7s where I wanted the car level to change oil, I use wheel stanchions on the rear wheels and Jack Stands on the front cross member. Note, with my C7 as I did when jacking the rear of my E-Ray when removing the rear wheels, used my usual MO of keeping slight pressure on the jacks as an extra safety.
