Porsche Brembo 996 BBK conversion

OK, mystery solved -- I heard back from Eric at Rally Road.
Those washers were shims for the caliper brackets, not crush washers.
.
This reminds me that I forgot to update the following:

How well did the Girodisc boots seat into the caliper? On my rear calipers, the large boots fit fine, but none of the smaller ones will seat correctly.

I was able get the smaller boots to seat. After Girodisc checked if the parts were correct (they were), the suggestion was to use a block of wood and a c-clamp. I used the Girodisc pad spreader, which got them to seat all the way.
One important detail is the boots need to be installed dry. I got a little assembly lube on one of the boots, which kept popping off, even with pressure. I cleaned it up, and it stayed seated.

Isn't it a banjo bolt into the caliper? The crush washers should go on either side of the eyelet that the banjo bolt goes through.

I have the Rally Road lines and brackets for the rear brakes. Included in the mix were 4 copper crush washers. Any idea where they go?
I tried in-between the line and caliper, but the gap is too big and the washer floats around.

(I can't remember if Rally Road included instructions -- if they did, I can't find them, and I apologize if this was covered in them.)

Yeah the dampers are extremely essential to knocking out the vibration. I live with the squeal so I don't have them rusting inside my calipers.

Funny, I just started getting a squeal when I do medium-strength brake events coming to a stop at low speeds. If I lighten up pressure on the pedal, it goes silent. It's not a "screech" as much as a resonance-sounding kind of wail. I'm not running any piston dampers (I ripped them out, but one caliper still has the things rusted into the caliper pistons) but I believe my pads have the vibration dampers. I'll have to double check.

Does that match what you're experiencing? These calipers aren't on an M3, they're on a 997.2, but that shouldn't change anything.

Yes, that sounds like it’s the same. It also will not squeal when you stop quickly with firm pressure.

yes and I used new shims each time.

Do they both have the dampening weights at the top?

What fcp pads is everyone running for street and track? Looking to buy a set of each with there lifetime warranty. Thanks!

Textar oem for street, got hawk DTC-60 for track but I don’t think that’s an option anymore... might have to pick something else.

started with brembo pads now running Akebono pads

Sorry, I can't keep track -- what pads are you running again?

Thanks!! If I could just cut the squeal by 50% would be fine. Honestly the squeal has prevented me from driving the car.

Which comment was this in reference to? I want to make sure I am not missing something.

The post right above it.

My rear 996 squealed like a dump truck with ds2500 pads. After a track day all is quiet now.

I would expect the OEM rotors to be higher quality than those ECS ones. Could be wrong though.
