Had some dealings with a guy who works on Corvettes (only) for a living and has for years. In his shop he has a couple of lifts, floor jacks, and a set of ramps similar to yours. Except his are bigger and heavier. 2x10's or 2x12's, I don't remember exactly, and longer boards (more gradual climb). He said he just likes them. Quick and reliable.

WAlmart sells a set of ramps with a gentle incline. Super sturdy and less than $40 for the pair..no need to spend a bunch.
Never heard of guys needing pucks on anything newer than a C5, just jack it up.

I have a couple small pieces of anti-fatigue mat that I stick on the cups. Sometimes just a rag. All you really need is to avoid metal on metal, at least here in Ohio where the slightest amount of bare metal turns into rust just setting.

Yep. It was dumb. That is what I like to call: "Worryin' about chit that ain't worth worryin' about." That is one of many reasons why I don't own that car anymore...and don't miss it. 
Now days, I just jack my car where Chevy says to, don't worry about it at all, and I have it on 4 jack stands in about...4 minutes.

Dittos - you could buy two and cut a slot in the top one. If you've never cut a hockey puck, you won't want to do it by hand. I used hockey pucks as body mounts on a truck project and the height I needed was 1.5 hockey pucks. Cutting a puck in half with a table saw was an adventure.

So I've wondered this for a long time; if you cut a slot in the puck, that is for the pinch seam to sit in, right?
So one of the problems with jacking C4's is that on some cars, the 'glass rocker is as low, or slightly lower than the steel pinch weld (so I've read). This can cause the jack pad to damage the rocker lip. On most cars, the rocker lip is about 1 cm higher than the steel pinch weld. Wouldn't a puck either flexing (rubber) or worse, with a groove cut into it, only exacerbate the issue? I've never understood how the puck actually helps anything.

I am another one who doesn't see the need for a puck to jack up a C4.
On C5's and later, the jacking points are masked by the rocker panels so there is no way to put a jack onto the frame without breaking the rocker panels. I use actual hockey pucks I got from a sporting goods store for my C5's.
My C4's have the rocker below the pinch welded metal, so I jack further inboard on other points. I also had one section of the pinch welded metal be slightly offset so that one of the two metal sections was lower than the other by a 1/32" or so. When I jacked there, the lower section deformed. I didn't like that, so I adjusted my jack points to further inboard.

I’m sure this is sacrilege to some..! But I fixed the problem of the glass rocker hanging lower than the pinch weld by cutting the low hanging part off with a utility knife! Now the glass and metal lip sit flush with each other and I can jack away with no worry of stressing the glass rocker. I figure if anyone wants to lay under my car and complain about me cutting off less than 1/4 inch of plastic/fiberglass from my car thats their issue, lol.
