Several sets of 996tt front brake calipers for sale, do they fit? Or do we have to run either the 928 GTS Big Blacks or 993tt Big Reds only?

Olli has done the 996 adapters.

Not if you have mo30.

I believe bolt spacing is different, and since they mount radially, adapters seem unable to work for M030 (altho Olly says he can do it)

The problem with M030 hubs and spindles is that you have to run M030 calipers and rotors unless you find a 130mm radial mounted caliper that can take a larger rotor and/or build custom rotor hats =$$$$

So you CAN with a regular Late turbo spindle?

I am running the 996 tts on my 87. Sam Shalala made some adapters for Bruce (95ONE) using my adapters as a guide. You may try to get hold of Bruce and see if he had an extra set made.

OK, turns out you can buy Big Blacks from Sunset brand new for $285 each. No reason for me not to buy brand new calipers that directly bolt onto my M030 hubs.

Next question, I know the 965 rotors are a direct bolt on with the Big Black calipers, but can I run the 965 3.6 rotors? For whatever reason they're $75 cheaper (each!) vs the "regular" 965 rotors...

You can run 928 GTS rotors or 965 3.6. 3.3 965's at least in the US did not come with the big red/ blacks Brembos

Yup, 99% sure that's what I ran for a while. 964tt or the 965 rotors. X-drilled. Cracked after 1.5 race meetings. Cheap...but not if you have to replace them more often.

95ONE

No extras. Sam still has the program in his cnc mill. He can spit out many if he finds the time.

AND... Thanks again for the use of your adapters BOB!!!!!! although Sam and I prettied them up quite a bit.

996 six pots are easy to install under 951, if you car is not a M030 version (we did first conversions about 6-years ago). If your car is a M030 version, you should look 997 six pots. There might be a possibility to fabricate adapters for these. 997 calipers attachment holes distance from each other is a bit wider than 996 version have.

Cayenne rotor is 330 x 32 and inexpensive. A Wilwood Integra or P6R would be the solution to the M030 mounting problem with that rotor.

Sticking with Porsche parts for the brakes. I know they work, I know they bolt directly on and I know there's a ton of brake pads made for them.

TonyG ran the 965 rotors with no real issues with cracking. I'm going through a set of 951S rotors a season due to cracks, hopefully with the larger 965 rotors I could get them to last 2 seasons. They're only $30 more a rotor vs the 951S ones...

I have had the same 996tt rotors for about 3 years now. Having said that I am due for a new set but they have had a lot of hard use thrown at them. OEM rotors are relatively cheap and that last on these cars.
