I went down a rabbit hole last time and eventually settled for Raybestos sets, with EHT pads, front and back.
The front pads explicitly stated that they came with the mounting kit (all the little thingamagingies) - turned out the lacked the noise/vibration clips/whatever they are called.
Looked at the site - they also sell a separate mounting kit (same name as the thing advertised with the pads, "mounting kit" or "assembly kit" or whateverit was), containing the same things, plus those shims.
Called Raybestos support - they picked up on the first call, obviously in the US, because 1) I could understand what they were saying and 2) they sounded like I owed them money.
Guy listened to me for 15 seconds and said "if it's listed as coming included then it comes included". Then when I asked why the separate small parts kit they sell is also called the same name but has extra stuff - he hung up on me.
I mounted them, and religiously followed the procedure for bedding the pads in. A dangerous one, as going X times to 55mph in my neighborhood is fun.
Anyhow - did all that. Well, best brakes ever. No contest.
The rear right rotor rubs on the edge of the parking brake pad, but I guess that's fine. Or at least I decided so after taking it off and putting it back on a million times.
A love story to pass to the generations to come, except - now, 29000 miles later, the fronts vibrate, and have an increasingly troubling dead time before they bite.
I drove 400 miles in the rain and mist yesterday, and by moments it felt like close to a second goes between touching the brake and having some response. So it's way worse in the rain.
Sliding pins and everything are new. Grease used where instructed.
I loved how they worked when they worked, but I'm not sure I'll go for them next time.
Which might be soon.
