I can't seem to get at Zertec's web site at the moment (can DNS resolve and ping www.zertec.co.uk but no HTTP connection). Do you guys happen to know whether the Zertec and/or AP kits you're talking about are for all four corners, or only the fronts? In case you're interested, for comparision I have the Tower View monster brake kit on the V8S, consisting of 305/30 ish drilled ventilated discs all round (the usual fully floating discs with gold anodized bells), asymetric 4-pot calipers allowing quick pad change on the front, single pot floating calipers on the back, braided hoses, adjustable brake bias and so on. A smidge over £2k. Awesome stopping power.

[quote]the AP-Racing kit for £1500? I have 345mm on my M5 now, but the stopping could be better.
The general consensus amongst braking experts (the people who use them, not the people who sell them) is that AP are very good, but Brembo are a lot better.
I've got the first of the Zertec developed Brembo 8 pot kits on my Cerbera. This includes the 370mm grooved discs and 8 pot 40 pad callipers at the front. It was a conversation between myself and Clive (the boss of Zertec) which inspired the development 
.
The standard brakes on the Cerbie are AP 4 pots at the front, and 2 pots at the back. The problem I've been getting is serious brake fade on track days (and a couple of cases of brake failure) 
.
I gave Clive the brief that I wanted "the biggest brakes you can fit inside an 18" wheel". After a chat with his brake man (who also works in the WRC dept. of Brembo, and usually works on things like Colin McRae's rally car) came up with this setup. A trip up to his place for the car, and a week later (he had to design and manufacture all of the custom bits) and I had my new monster brakes.
They're infinitely better than the AP's that they replace. Even on the road, they're beutifully progressive, and they stop you like you've lobbed an anchor out the door 
.
The rears were good enough not to need replacing, so they're still the standard AP units, but the pads have been changed for some DS3000's.

James My question was in general, but as most of the TVR users have bigger brakes than the Elise users on the forum I decided that the TVR forum was the best place for advice.
I have a Corrado VR6 with 330mm AP 4-pots (with DS3000 pads) and an M5 with 345mm standard floating caliper set-up.
Now I know the M5 weighs 500kg+ more than my Corrado, but the AP set-up stops so much better than the M5 so I was considering an upgrade to the M5 brakes to either Brembo or AP!
Therefore when I saw the info on the Zertech system I wondered whether the floating Brembo set up or the AP kit would be best suited to aggressive track days stopping a 1800kg M5 and also suitable for the road (such as the AP kit on the Corrado!).
Just a different point of view I guess, but on Mitsubishi Evo 6, just about everyone has warped the Brembo front disks (332mm) and the only proven solution is to fit the AP discs and calipers.
Surely the way to go is the ceramic discs which should soon be available (used on the original Elise and now on the new 911). Don't know how long it will be, but in the words of Fox "The demand is out there, some where"

These brackets are quite small and the weight saving would be negligeable, but I imagine steel would be more suitable in this sort of highly stressed application. I've had three different adapters on the V8S (for different brake upgrades) and they were all steel. Just curious ... Peter Humphries (and a green V8S)
Richb, the custome made Aluminium (Al) adapter is needed to connect the caliper to the std upright.
