Jacking procedure at tire shop
So I took my coupe to the tire shop for wheel balancing, and I noticed they unlatch the hood, the rear hatch and both doors. The tech told me this was becasue of the design of the frame and to prevent cracking.
I'm not sure what he meant, are there any techs out there who could expand on this?

back in the day guys would do that because frames sagged and bodies could possibly crack if you jacked them wrong. Not and issue with a C5. The frame is rigid enough. pretty much an old wives tale now.

I doubt any cars less then about 10 years old flex enough you need to worry about body damage when you jack them.

Just more of what I always refer to as your grandfather's 1960's automotive technology. The Hyrdroformed frame of a C5 is 400% stronger than previous designs. it was designed to accommodate a Convertible, without having to use two different parts. While the convertible was seen as a down the road approach ( after launch ), we were looking to launch the C5 in 1997.
These old and antiquated shops that do things like they did them back in the 60's are places I would never take my Corvette. These places will " Gun ON " your lug nuts and cause more problems. Most places use torque tubes, unfortunately, whatever torque tube is on the gun, that's what they use. I suggest to anyone to recheck your lug nuts to proper spec after anyone touches your lug nuts. Sometimes these guys torque these lugs to 140 ft lbs. they are suppose to be 100 ft.lbs.
FYI and Merry Christmas

Thank you to all who replied, I appreciate the enlightenment. As always a wealth of information here on CF.
Yes, they did use jacking pucks, the ones I produced from my trunk.
And they did hand-torque the lug nuts to 100lb ft.

No problems when jacking my 2002 Z06 or my 1992 coupe, although I have not tried the 92 with the roof off. There is absolutely no problem with opening and closing the doors, hood or trunk when they are jacked up at 1, 2, or 4 points.

To the OP,
Did they use jacking pucks? I went to a shop once and brought my own. Shop owner asked where I got them as he had cracked several Corvettes trying to lift them and didn't know they were required to lift the car. Probably never told the owners of the damaged cars either.

And then try to remove them on the side of the road later when you have to get them off. Nobody touches my Vette, but my daughter's Jeep were on so tight a breaker bar barely got them off.
