Thanks. I have no idea what is REALLY on it since I just can't remember at this point (and am totally sick of this) so I'll get it in writing what exactly is on the car and work to get what you describe since I'll do anything at this point to NOT HAVE SQUEALING BRAKES.
Also, the EBC pads seem to totally suck so far in terms of stopping ability. Serious brake fade after the back to back 60 mph to 20 mph hard stops.

I replaced the completely stock, original rotors/pads/spiders in 2006 with factory parts. At the time, my 993 had around 35,000 miles. I did it because I wanted to.
Nearly 30,000 miles later, and the brakes still feel like the hand of God yanks my sled to a stop. And they do so with nary a peep.
I also flush the brake & clutch circuits every year, but that is not at the heart of your issue.

UPDATE: 5.7.14 - Got my car back today after renting a black Kia Soul for a week. This is what they did (see below). The squealing is A LOT less so far. Barely heard it for the little bit of driving I did today after I got it back. We'll see how it goes... Just wanted to report back in as some have private messaged me about it.
"BG ANTI SQUEEK BG 100-S, 1 @ $20. Drove vehicle and bed new brake pad and rotors in. Customer complains of squealing noise. After multiple miles of harder driving, squealing was reduced significantly. Remove front pads and apply special anti-squeal compound to pad face material and test.
This vehicle's brakes are "race" quality and some squeal will always be a factor. We use factory parts and procedures to minimize this noise, however it is a common problem and the customer must use the brakes hard to remove the "glazing" that can cause the squeaking.
We have done everything with in our power and the customer this will have to maintain the brakes to squeal to a minimum. We are not responsible for the design or way in which the customer uses of any of the vehicle components, including the braking system."
Recommendations: Customer must heat cycle the brake pads to prevent/lessen brake squeek. There are only two street (non-race) compounds now available and these brakes are race quality and will always have moments of squeaking under certain conditions."

OE does not necessarily mean no squeal. Mine, ordered from Sunset as most of my stuff is, squeal under light braking. All OE. I do not have the spiders attached though, to facilitate quick pad changes for track days.

+1 to Bart1's comment ... I also run without spiders or sensors for quick swap to track pads. I have little or no squeal with OE Textars (in Porsche packaging). This is a relative statement ... with the track pads I have squeal like a banshee so I might be thinking I have no squeal with the OE's by comparison.
Another RL member suggested washing off the disks ... and that helped for awhile but the squeal has always come back when using the harder compound pads.

So the shop exhausted their efforts with street pads, and have settled for race pads? They will squeal here and there for sure. But as long as it's at an acceptable level, and you're ok with that, life is good then my friend, Steve

Porsche rotors in Porsche boxes + Porsche pads in Porsche boxes + Porsche vibration dampers in Porsche boxes = quiet, normal braking.

As others have stated here, when i did my brakes 2 years ago i installed Pagid pads.......brutal squealing, after 200 kms tossed them in the trash and installed Textars, almost no noise.

Which pads are in there now Steve?
I have big reds with oem rotors, like new textar rear with spiders. Fronts are squealing Pagid pads with old spiders. Waiting on new front textar and spiders from fd motorsports. Can't wait! Right now my front squeal horribly after 5 stops.

????????????????????? This is all I would ever want! Why did I not get that? I just don't get it. I really don't. I begged then, pleaded with them, do ANYTHING TO STOP THE SQUEALING. ANYTHING!!!! I'm lost. Truly lost. Why didn't they just put on what you're suggesting? You know these guys. Thoughts?!?!?!?!?!
If you asked for something specific and they did not listen to the customer, EVEN if they disagree with it, they should still do as the customer requested, or at least discuss the reasons they disagree with you and come to an agreement on what should be done.
I have used no fewer than 5 different mechanics locally for a variety of things on my 993, until I found my most recent one. All of them are a little different and have different thoughts on things.
Best of luck.

I think you need to order all the parts you want and then take them to a shop who will install them.
I just fixed my brake squeal tonight! I ordered C4S/Big Red Textar pads (yellow box) and new Porsche dampers/spiders from FD Motorsports. (Thanks Mark!)
I bed them in tonight and there is zero noise! So happy
I could have reused the spiders but didn't want to risk having to wait for them if mine didn't peel off. They easily came off the old Pagid pads. Btw these pads were breaking apart really badly. Check out the pics.
Steve if you want a set of used front spiders for Big Reds just PM me.
