Default Rally Road Rear 996 Bracket Question

So I bought a set of Rally Road rear 996 brackets from a forum member. I contacted RR and they confirmed that the brackets were their new design for the D737 pad (I'm sure we're all familiar with p0lar's work on this).

So I'm installing the rears today and I can't get the inner pads to seat. They're not clearing the bracket, so I can't get the pad pin in. The brackets have a recessed area which I assume is for the pad to sit in for the extra clearance, but it's not even close.

I emailed RallyRoad but since it's the weekend I probably won't hear back until Monday. Posting this in case anyone has an idea what's wrong here? Am I doing something wrong? Is something wrong with the brackets? Are these not even the right brackets maybe? Ugh.

Recessed area the pad does not clear:



Pad sitting on the bracket:



This is the pad pressed against the rotor:





Mounted off the car:



If I put the pad down in this recessed area, it's not centered and there's a huge gap (not to mention impossible with the rotor lol, just demonstrating):



Yes, the pad is the D737 pad lol:

No. That's for a 996. This is for an E46 M3.

I wasn't aware you were trying to overcome the rust ring. The 1208C pad is a fitting pad for this situation.

Yeah the new RR bracket is supposed to accommodate the wider D737 pad. I read up on all of p0lar's research on the subject and wanted to buy his brackets instead of RR's but I couldn't get a hold of him.

Anway, this pad is obviously not clearing the bracket so I'm not sure what's up. I have a feeling I have the E36 or non M 46 version.

Well I tried searching other models on RR's site but they don't have updated images for the newer brackets. I also searched Google pretty extensively and cannot find any pictures of the new design for our cars, except for the FS post I bought them in lol. I guess if someone sees this holla, otherwise I'll follow up for posterity when I get in contact with RR.

Good morning, gents!

You're encountering one (of two) potential issue(s).

1) The pad you're using is exceptionally thick, possibly more than 16mm? This is causing it to be a very tight seat in the caliper without the clearance on the bracket.

2) The D737 DOES extend down further, but only by about 5-6mm. If the edges of the pad don't clear the bracket by that much, then that's also likely an issue.

The solution? Different pads (ugh), or you could try my brackets -- except that I still don't have any in stock. My brackets mount to the OPPOSITE side of the mounting bosses so the pad depth or width is never a concern as there is simply no way for them to interfere.

Let me see what I can do to expedite the build of those brackets.

Woke up, saw your message, brushed my teeth, and went to the garage:



As for the pad height, its hard to measure because it varies but here's the highest and lowest point and also the only point you can kind of read on the other side where the guide pin exists that must be removed.

@p0lar: when do you think you might have more brackets available?

I emailed Rally Road on Saturday, called and left a message Monday, called Tuesday, called and left a message Wednesday, called today. Nothing.

I understand the frustration. I really didn't want to make another set of "v1" brackets, despite the fact that they're dual duty, as I want a set that require zero point zero intervention of any sort based on the location of the upper wishbone mounting bolt/boss. It would be nice if I were able to get a count of the number of people who need these so I don't overspend since I have to front all the material and labour cost all at once.
