I would like to add that the '86's are different in that they need a completely different back spacing on the rotor than any of the newer models. And of course, they're a huge pain in the *** to remove/replace compared to the newer ones. I believe the caliper adapters would be the same for 86's as 87's and newer (non M030) .. not 100% on that.

I believe the difference is the MO30 hubs/spindles mount the brakes radially. (Bolts from top of the caliper) This is why the 993tt, 928gts brakes bolt right on those. its the proper mount. An adapter for the 996tt mono blocks would be very difficult to do since the only difference would be a slightly wider mounting bolt spacing (Than the 993tt calipers) that might not be enough difference to clear the origin holes. Those would have to be filled in with weld, and new ones drilled and tapped.. Not easy.
The Stock brakes for a non M030 951 mount axially. (from the side) So a fairly simple "L" bracket is all that is required to adapt. So in that sense, Mo30 difficult. regular old '87 up easy.
But my problem is all the adapters for the regular hubs are made with the narrower bolt spacing for the 993tt brakes, not the 996tt mono blocks. This is why I need to know where Bob bought his adapters from. I truly don't feel like measuring and waiting on my CNC guy. He's just not fast.

For 99.99% of us, the Big Reds/Blacks are easily sufficient. It's only on really high powered track cars that the difference would be apparent.

So, to reiterate: I'm looking at 2004 996tt big blacks, four piston calipers, rotors, and pads for 600. The 996tt calipers should work with my non M030 spindles, rotors are a big ?. Anyone have words of caution before I pull the trigger?

You're getting your references mixed up.. " Big Blacks" is a 993 turbo / 928GTS reference. They are not the 996tt mono blocks. The "Big Blacks" are a few pounds heavier and are a 2 piece construction - two halves bolted together. They are not the newer Once piece - Hence Mono block - design. (For strength vs weight characteristics) Ones for the 996tt
EDIT:
But since you confirmed that these were coming off a 996tt.. then we will consider them the Mono blocks. I myself, don't know who sells an adapter for them.
still unsure about rotors

Thanks. The mix up is partially due to the owner of the 996tt who is describing them as 4 piston big blacks which he replaced with the brakes from the GT2. Did 996tts come only with the monoblocks? I guess I'll have to get pics from him.

I believe so. , Or a 6 piston option that I think your guy has upgraded to.

six piston on vehicle craft.
June 22, 2004,
quoted from vehicle craft
"Six Piston GT3 Caliper uprades in the works. First car to get them was Roy Chongs 944 Turbo racecar. We are planning on the 964, 944T to start off and actually have the capability to do this now."
First install on Roy chongs 944 Turbo racecar:
different site listed this:
Brembo 996TT front 6 Piston Calipers
PART #'S
996.351.431.30
996.651.432.30

My six piston GT2 front & GT3 rear monoblock system. This system was designed years ago by my friend Pete (Pete95zhn here on Rennlist). Glad to know also Vechile craft has made it 
Do they offer rear conversion as well?
Most likely Vitesse Racing can offer you such a kit in the near future (adapters)
Adapters for M030 spindles are under design process as well.

For any brake upgrade on an 86T, I think the best way is to swap out the 86 spindles and hubs for 87+ 944T/S2 or 968. You can use M030 or non-M030 with radial caliper mounting adapters.

As an FYI - I just ordered some replacement new 951 S calipers and they were 377.78 each, The big blacks were quoted 675.00 each from sunset

Another concern I had was keeping the stock m/c which I felt was not the best option. Seems to be some divided opinions on this. Olli and Pete liked their setups. (Such a shame about Pete's car as it was clearly one of the very best out there.)
