Not that I have decided.....About this advice I got from a reputable Corvette mechanic.......but he says jacking pucks can dent/bend the frame.
Now then, these things have been used on vettes for years, and I had never heard that before.
Since I now use a floor Jack and race ramps, I can have the car in the air in 5 mins. No need for jacking pucks?
I have a "Cheap" set that are made from hockey pucks and screw eyes. They don't stay in worth a damn, which makes them very easily removable. Here is a similar set for $30

They actually use pucks in the assembly plant, but the difference is most owners use a floor jack that lifts one (or two) points at a time, where the factory lifts the car by all four points so they are always setting flat on the frame.
Lifting at an angle to the frame can dimple the frame a little, but not enough to cause a problem.
I had some pucks made by a local machine shop and I still prefer using metal pucks over plastic or hockey pucks that can deform under load.
Is there a set of jack pucks that is easily removable?
Right now I have the standard black plastic pucks which work great, but once they're in there's no getting them out, at least not easily.
I want to use the holes to secure the car to a trailer with t hooks, so I need to be able to remove the pucks at will depending if I need to jack up the car or tow it.
Thanks

Wouldn't deforming under load be preferred as it would spread the load more evenly across the contact area? I think it would be better for the puck to deform rather than the frame.
I use the long Katech pucks and they work great. I wouldn't consider leaving anything in all the time. It only takes one time to hit something and really make a mess. It doesn't take that long to put them in or remove them. I use an AC jack and it works great. If you use the AC rubberpad it won't hurt the pucks. I also bought some cross beam adapters so that I could lift the whole front, or rear, end at one time. I found the guy that makes them on ebay and gave him my measurements. He has photo's of my yellow z06 on his discription.

Denting the frame is sort of it depends on what you are doing. GM Shop Manual says to use the pucks in the rear shipping slots and not the fronts as there is plenty of room to clear body panels at the front.
However, if you do what I do which is to use one puck in the front to jack the car high enough to change both the front and rear wheels ala NASCAR style you can eventually dent a steel frame C5/C6 as you are putting a lot of pressure in one small area. It doesn't hurt the frame but some people will freak out. Doing the same thing on my C6Z didn't dent the aluminum frame at all.
As for using the slots for tieing down the car that is probably what the factory did to ship the cars on trucks. They tie them down with over the tire straps that hold them in fore and aft position and at a steep angle while using the shipping slots to pull the cars down on their suspensions so they don't bounce around and hit parts of the trailer above them or another car. They tend to pack them in tightly.
