I have seen pictures of the latest D2 calipers , and they look to have changed the seal design , perhaps they have encountered the issue's I have highlighted above , as far as I can see the K sport calipers haven't been changed yet.
When we were sent emails about the latest D2 caliper kits , they were only offering kits with drilled discs not grooved , which is a backward step , your buying a kit to increase the performance , and drilled discs taken to high temps will crack around the holes

Mind you D2 also appear to have put there prices up, which pushes the 6 pot kits up towards AP money. Especially if you want floating rotors.

I've just fitted a set of Stoptech ST40's to my Scooby. This kit new cost along the lines of 2grand! I bought them second hand with an exchange for my standard 4pots though. Has anyone got experience on these brakes? I've not had a chance to really try them out yet!
I see loads of k sport, ap, brembo talk, but not much mentioned about Stoptech.. what's your thoughts?

Yeah i suppose, I'm hoping to take the car for a good run to try them out myself, was just wondering if anyone else had experience on them
Anyway, once I get a good feel of them, I'll write a little review on here, thanks again!

Not having a go btw, I'm just curious about your statement..
Yeah don't worry, I paid a fraction of that cost! Lol

Is there any evidence to back this up? If they are the same brakes, why is there completely different reviews between Brembos and Stoptechs? Why is there such a difference in price? Why are Stoptechs only manufactured and sold in the US? And why are they only sold as trade and not to the public?

As for your other questions , I've no idea why , I guess you'd be better asking them
The best calipers available in my opinion is AP , Alcon are also good , but in the road kits with use chrome plated mild steel pistons , and these rust and stick , we had a customer last week who sent some used 18 month old front calipers , and a pair of brand new rear calipers which he just wanted powder coated gunmetal grey , the front piston were all shot and needed changing much to the surprise of the owner , we had to change all the front pistons and they were 6 pots , not sure why they don't use alloy pistons as AP do

Are AP's a monoblock design ??

It depends what the car is used for , hard pedal pressure can cause a caliper to flex , a monoblock caliper has less chance of it happening , but if calipers are designed properly it shouldn't really be an issue.
Do people in road cars hit the brakes hard every time they brake ?? Not even my WRC Impreza rally car has monoblocks , they have 2 piece AP's front and rear.
I think with the advancement of CNC machines I'd of thought that its cheaper to produce monoblock calipers like the Alcon ones .

My line of thought that is many owners wanting big brake kits have big power cars and even on the road will really put a set of brakes through there paces (I used to with only a shade over 400bhp). Many of these cars are used on track where very very hard brake use is unavoidable. Even the best designed 2 piece caliper will suffer flex when really used in anger surely or am I completely off track ??
Flex in the caliper is something you really want to avoid I'd of thought so for many a monoblock caliper would be a better option ??
Whats the price difference between a AP 2 piece caliper and their monoblock caliper ??

When I'm talking hard braking I'm talking race / rally car on slicks , race suspension and race pedal boxes not servo / road master cylinder , totally different kettle of fish to a tuned road car on the track , but as I said , my rally car has 2 piece AP 6 pot front and 4 pot rears , good enough for Prodrive then
And when we are talking flex , with a properly designed caliper , I doubt you would see flex looking at the caliper , you would probably only see it happen with digital measuring equipment measuring 100th of a mm .
The only calipers I have seen flex are the small Wilwood calipers

I'm sure you'll find evidence if you search , I'm not going to spend time doing it lol , they use a Porsche shape pad , it's been a well know fact for years they use Brembo calipers.
As for your other questions , I've no idea why , I guess you'd be better asking them

Infact, everything I've read so far says that Stoptech out-perform Brembo, and thats why a lot of people (in the US) upgrade their OEM Brembo systems to the likes of Stoptech.

Ok search for pictures of there calipers , and search for Porsche calipers , you will see they are the same , you won't find and pictures on stop tech calipers being made and machined by them.
It's well known to anyone in the business

Actually I just searched myself and it does look like they make there own calipers now so I apologise for that , there are photos on there website of them being machined , these are the ones I was talking about when they did use brembo calipers
http://www.europeancarweb.com/tech/0...brake_upgrade/
These are Porsche calipers , and they also used Ferrarri F40 calipers , they must have started doing there own in the last couple of years
