lol you think what you think, and we will agree to disagree, well done on your first class honours degree in engineering :-) shame you don't know much about brakes.
people just must make stuff up on here !
If you unload a wheel you might lock it up on a corner as you state you are braking in a corner, but go try it on Senna straight and come back and let me know if ABS trigger at 120mph.
Why would we agree to disagree? This isn't a subjective matter.people just must make stuff up on here !

Your statement of 'shame you don't know much about brakes' is quite indicative of your thought processes, because it's completely meaningless. What is there to 'know' about brakes in this instance exactly? We were not talking about calculations or force equations. My statements were based purely on my own empirical evidence.
I obviously also wasn't talking about unloaded wheels, as they could clearly be locked at virtually any speed. Having the track experience that you do, I'd assumed you know that the initial braking for Riches IS done on the Senna straight whilst travelling in a straight line.
As regards to people on here making stuff up, just ask yourself one simple question....why would they? I'm not lucky enough to be buying a GT4, and therefore have no reason to justify either type of brake. For the record, I'd probably be tempted to get PCCBs because of their overall benefits.
I was merely responding to the post about whether the brakes or the tyres are the limiting factor for a single stop at high(ish) speeds.
I know for fact I can trigger ABS at 120 mph in a straight line. I could demonstrate it to you at will. (We could bet your shiny new GT4 on it if you like?)
I have no doubt you will still say I'm making this up, so I'll ask you one simple question:
If you are so sure that a Cayman S cannot lock the wheel at 120mph, you must by definition know exactly what IS the maximum speed lock up can be achieved.
So what is it? 80 mph? 100 mph? I'm curious as to what you think.
I apologise to everybody else on this thread for the off topic conversation, but I struggle with being called a "deluded dreamer who knows nothing about brakes" and not responding.

point is there is nothing wrong with the products , so why slag them off.
day on day people are posting horses
t.
You read what you want to read, and not actually what was wrote. I merely said that dealerships applying these products is a bad idea and that there are better products than Autoglym. That is a fact, and I'd be 100% confident that for the same price as this service, a professional detailer will use a much better product line to give a long term protection on the paint.day on day people are posting horses
t.You seem to be the kind of guy that would go on detailingworld and argue the toss with seasoned professionals just because you feel like it. Shame really.

Shame about all the bickering and handbags on here. Picked mine up on Friday and pleased as a pig in sh*t. Not had a GT car before and it would be useful to discuss some routine issues like first oil change (after run in?) and the large amount of crap the side pods hoover up - so maybe washable air filters?
Must say the car feels better than I remember at the PEC day. The car seems to cope ridiculously well with the sometimes narly B roads in the peaks.
Mine came with cup2s

The 991 GT3 'manuel' warns of brake squeal being normal and in fact my steels have done so from day one....be interesting to learn what the GT4 'manuel' says although if the brakes are identical GT3 some squeal is inevitable.....
From memory the 4 manual says says the same but I haven't had any squeal.rk123 said:

That's the nuts and I've built my car to pretty identical spec apart from CS. TX.
I did originally opt for black wheels but it's s Matt black and wasn't sure so have gone standard titanium and will decide later .
Quite surprised how many have opted for GR but then I guess it's s good free GT colour. Just can't bloody wait to get mine now

Are you following the very strict run-in regime?
For what it costs (especially if you go and get your own oil from Costco, Opie Oils or similar) then I think an oil/filter change after run in is worth doing, if for nothing more than peace of mind. I do annual changes on my GT3 even though I don't run it that much any more. Again, just don't feel it's worth the risk.
Any pics of what the side scoops are collecting? And how to the scoops look? Picked up any stone chips yet?

Well I stay out on track for a long time where the better cooling of PCCB's makes one difference, ignoring the unsprung mass benefits ...
In my R which had PCCB's that I finished off after 32,000 miles -- at Spa, the refurbs from SICOM cost less than £4000 fitted with new pads all round --- which could be less than steels would have cost me over that time, with all the advantages for free.
I was very happy with the outcome, and accordingly re-specified pccb's on my GT4 which I will be driving at Oulton on the 4th November ...

That price for the refurbs does make quite a compelling case.
Do they refurb your discs or supply you with refurbed discs? Is it like a trade-in system where you give them your old ones and they give you a replacement set? And I presume you can do this as many times as you like?

Strict running in regime Jack?
My OPC says there isn't one just don't go and cook the brakes immediately .
AP says it's all good to go out the box they said on the Schmee video

I thought AP has also said more recently that people are running the risk of wrecking their engines by not following the run-in guidelines.My OPC says there isn't one just don't go and cook the brakes immediately .

I don't have a manual, but I believe it is something like keep below 4000rpm for the first 1200 miles.
I was wondering how many people are following the book, as opposed to what their OPC says.

Hadn't Heard that so some clarification from Porsche would be useful but then if that's what's in the manual that's the bottom line. 1200 miles won't take long to clock up. So do you think the GT3 will go if you fall for the gt4? I'm so focused on getting mine I've not missed the GT3 so far I don't have a manual, but I believe it is something like keep below 4000rpm for the first 1200 miles.

I'm sticking to the run in advice and also planning an extra oil change! Though I find the official run in advice (sub 4K) and the first oil change at 20k a bit contradictory.I don't have a manual, but I believe it is something like keep below 4000rpm for the first 1200 miles.

To be perfectly honest, since I got the 997 GTS (manual, RWD, Sport chassis and diff) I've hardly used the GT3. The GT3 is so immaculate now that I struggle to bring myself to get it out. The fact that the GTS is just SO good doesn't help much. Already done over 14k miles in the GTS since I got it last November!I think purely as a sensible place to have some cash right now, I'll be keeping the GT3. It's not costing me anything other than insurance and tax.

Come on now. Did I say that? David, you do have a real talent of twisting things to suit your agenda.
hence the wink, but as 3 posters on this page alone are NOT missing using their GT3's it says a lot for road use as I found out to my cost when I owned one.IF people were more realistic about GT3 ownership it would stop a lot of buying mistakes, hence we see cars with 10 owners !! but they are over hyped by EVO and on here :-p
So hence people have that want factor.
Lucky for you the cars now an investment and for that it's a winner. :-)
we all love forum banter :-)
Are you doing the Evo how fast this Sat ? be good to say hi if you are there.
