Are all the pieces of the anti-rattle clip kit in there how they're supposed to be, including the shims?

What you probably have is not really "ceramic". If it was you would have no grip when cold or wet and it would have chewed up your rotors. Many manufacturers use that term but it is not "ceramic". They use it on the box so they can charge more for the pads. Examine the pads. You should find 2 letters on it somewhere indicating it's true grip. Look for EE or FF or something similar. That will tell you what you really have. As for springs, they come in all diameters, lengths and coil diameters. If you get one that has a coil diameter that is too small, it will just lose it's tension when it gets too hot. If it is not properly heat treated it can lose it's tension too. That is why I said to get the springs from a Delorean vendor, they have the size that works.

I had this chirp issue for many years and squealing front breaks when coming to a stop.
I finally fixed both issues with the anti-rattle spring and anti-squeal shim kit. Aka: Front brake hardware kit. I installed the kit this spring and they have been quite ever since. The original spring style is NLA. The aftermarket hardware kit uses a different style spring than the original version but seems to work. I got the kits 1 per side from DMCMW.

"The original spring style is NLA." FYI, although they may have been on your car when you bought it, no Deloreans came from the factory with brake anti-rattle clips. That is unfortunate since this was a common complaint since day one. Many ago I started using lightly modified A.R. springs in the front and clips in the rear brakes and this has always solved the clicking or "threading" problem. DMCH vendors started using a little different style clip some years ago and it doesn't matter which style you use as they both work. Of course I would prefer you choose mine for an obvious reason! In both cases these clips are designed to eliminate pad clicking only and will not solve squealing issues which have other causes.

David, If you are addressing me, I most certainly know that I have ceramic pads. I find it pretty ridiculous that you would suggest that any of us that mentioned them "probably" don't have them.
I also find it troubling that you repeat incorrect information. Since you don't trust manufacturers information, here is an excerpt of an article on comparing types of brake pads from Consumer Reports:
Types of brake pads
There are four general types of brake pads for cars and trucks:
Semimetallic: This formula, containing about 30 to 65 percent metal, typically includes chopped steel wool or wire, iron powder, copper or graphite mixed with inorganic fillers, and friction modifiers that bond all the ingredients together. These pads are more durable and have excellent heat transfer, but also wear down rotors faster, can be noisy, and may not perform optimally at low temperatures.
Nonasbestos organic: Sometimes listed as organic or NAO, this type of pad is made from fibers, such as glass, rubber, carbon, and Kevlar, with filler materials and high-temperature resins. These pads are softer and create less noise, but they wear faster and create more dust.
Low-metallic NAO: These are made from an organic formula mixed with small amounts (10 to 30 percent) of copper or steel to help with heat transfer and provide better braking. With the added metal, there is more brake dust and they may be slightly noisier.
Ceramic: These are composed of ceramic fibers, nonferrous filler materials, bonding agents, and possibly small amounts of metal. Lighter in color and more expensive than other brake pads, ceramic pads are cleaner and quieter, and offer excellent braking characteristics without wearing down the rotors.
Here is the entire article: https://www.consumerreports.org/cro/...-for/index.htm
There are tons of similar articles on the topic.
To the OP, I have the DMC shim kit on my DeLorean that Jonathan mentioned above, and whether you get it from them or PJ Grady, I recommend it.

Maybe he's thinking of carbon ceramic rotors...?
