HOLY CRAP! I cannot imagine needing that much brake. Seriously. Super brag factor, but unless your going 200mph all day long how could you need that much brake.

- wow - anybody have any real 100mph-0 or other testing on these on 951? Just curious. because I cannot imagine needing that much brake

Need these brakes or not, they perform great and there's a hugh bling-bling factor as well

Here's several pictures taken of my and Pete's set ups:
















From last picture you can compare the size of 951 "baby" Brembo to GT2 six piston, GT3 four piston fronts & rears and 951 S calipers

So Oli, what difference have you noticed and under what conditions. I'm of the opinion that this is more than we need. I do however agree on the bling factor. I am to understand that apart from the weight that there can be other negative attributes when going massively oversized.

+1 Every run I make is over 100+ and the stock braking system work great for me. I can understand the additional security of knowing and of course, they do look freakin cool

GEEZE - that last pics makes me feel "caliper imasculated"

I just don't understand why you guys keep writing we do not need them. You are so right ! I don't need either a 3.0 liter turbo engine iam currnetly building. For me and also for my friend Pete these cars are just a hobby. We would like to modify them to the direction we would like them to be. 951's are not so rare, so they should leave factory original. If so, i just can quit car hobby and start to collect stamps insteadt of it.

To the question what difference i have noticed myself; none, because my car is still in pieces waiting for these brakes, 3.0 liter engine, new undercarriage and possible Audi A8 6-speed transmission.
I have been with Pete on a racetrack and have surely felt the stopping power of these brakes. I suppose Pete can tell more about the pedal feel.

Hey no offence by me Olli. I think you guys have done a great job and as you say you shouldn't have to feel that you're defending yourself, but I don't think anyone's is attacking you either. I have made enquiries about putting brakes that use 350mm discs to a race engineer and he said that there can actually be detrimental effects too. Not just a matter of bigger is always better, but if you've experienced Pete's on the track that's great and they do look fantastic too so no question of attack here, probably a bit of jealousy though. heheheh.

Unforunately I had to skip last year the event I was building my brakes, namely a trip to Nürburgring. That would have given me quite much information about track and Autobahn braking. Oth 'Ring is pretty easy for brakes, long straights allow brakes to cool. Our own tracks are shorter and at least the nearest can boil bad brakes ( and even std Porsche ones ).
Downside with these -especially with improved cooling- is that it is more difficult to get them warm enough, yet depending on the pads. Driveability, or brakeability (<-- funny word, is it english?? ) is excellent, limiting factor is tyre grip.
Pedal feel is is solid and doesn't differ much from turboS calipers ( overall piston sizes are the same ). Still I'd say that it's easier tho brake to threshold with these. And no fade.
I had an oppoturnity last autumn to drive a MkII 996 GT3 ( similar brakes, same size front wheel & tyre, I have MPS II, he had MPSC ) and I was astonished how similar the brake feel was.
GT3s weigh as much as our cars do, and many of us have more power. Why should we then use lesser brakes than factory engineers feel adequate for similar performance cars??

i never get tired of seeing those pictures.

+1. They're like special candy from an exclusive candy shop.

Makes perfect sense to me

Those brake calipers need their own set of *********..........

I absolutely love them and hopefully will be able to make it work with my Speedlines. That might be my only limiting factor.
Its funny, why people need to explain themselves about adding more brakes yet more power is always a pat on the back. Where the heck in the world do we go that fast? Not in US and we probably have our fair share of big bore/stroker 951 or 968 based turbo's in US.
I see a double standard.
Unbelievable!

You don’t need the larger brakes for the first hard stop from 150…you will notice the difference after a couple of 150 braking attempts….after 10 minutes on the track you will really really notice the difference!

In reality – the stock brakes are a better choice for typical USA street driving – they will work better when cold and they weigh less. But once you get into some serious fun the larger brakes will start to make a difference.

And they do look pretty cool!

OK, whats the circular adapter for?
