ORIGINAL: 944 man
Ive just realised that Big Reds, and Fake Reds are designed to lead the wheel, whereas 944 calipers trail the wheel, so the bleb dipples will be in the wrong place.
Can you swap them with the crossover pipe?
You just flip the Reds upside down, the Blacks are oriented the same as ours. Don't worry about the Bleb Dipples either. There is an Antidote for this condition. [

If you have the Mo30 you can bolt the Big R/Bs straight on Simon. If you want to move to 6 piston monoblocks then there is very little room to make a proper adapter. You will have to switch to Non Mo30 or S2/968 spindles and then use the adapters available from Olli's friend Anti. Remember that you will be moving up to at least a 350mm rotor and this will be very snug under a 17" wheel.
Pretty sure I saw a thread on Pelican where a guy called Mark made up an adapter to run on a smaller 330mm rotor...I think...have to dig that up again. Actually Olli can give you all the fitting details re what hardware you need. I know his friend Pete ran the 6 pot Big Yellows and I have a feeling these were not on 350mm rotors so perhaps it's not a problem.
I think the choice or perhaps reason of going up to larger brakes is not as simple as it seems. While there is the clear Bling factor which in itself is a fine enough reason. Nothing wrong with putting these on just because you prefer the looks. I think you have to weigh up the extra unsprung mass, the weight of the car, the power of the car and the use of the car. I've always thought if it was deemed necessary by the factory to put these on GT3s with less power/tq than some of us then why not our cars? Perhaps a simplistic view granted. I went to Big Reds a few years ago. Until I got them to work properly with all the associated hardware (s/s lines, ducting, race fluid, race pads, slotted rotors) I am not sure how much better they were than a well setup Medium Black stock scenario. However I also got faster in the car so it's difficult to be objective. I then had my pedal get soft after a few laps on new slicks back in 2010. With the extra cornering speed and deeper braking, the pedal started going to the floor. You may have seen the video clip where I'm having a play with a modified Evo and he eventually spins in front of me. This was probably fortuitous as I might have driven into the back of him had he not spun! So once my car went in for it's rebuild into a proper track car I decided that I would need more braking that I currently had. So slowly I built up an inventory of Front Cup Calipers, hats, rotors and had Dave McGrath of CEP in the US try quite a few times to work an adapter to fit with my Mo30 spindles. The last time worked..except it had the wheel sitting out too far due to less clearance between caliper and inside of wheel centre. At this stage the project has slowed to a stop and I'm inclined to just get a set of S2 or the like spindles and go from there. Oh and one more thing, I'm not entirely sure if you shouldn't change the master cylinder to allow for the larger piston area of the 6 pots. This has also brought more conjecture over the years. Some suggest shifting to a larger m/c from a 1990's BMW 7 Series but I don't think there is any conclusive proof of this having happened. I followed it up a bit and contacted the m/c manufacturer but they were unwilling to support or help as it could become a legal issue had I crashed due to brake failure. I also remember someone else working on this concept. Perhaps on Rennlist. It isn't an issue for me now as I've removed all the OEM brake system. Just to add to that, for the few laps that I did in my car before the crash, the brakes felt very good. Never put them under too much stress, but the modulation without the booster was very nice and better than expected.
