Right o then folks, im upgrading my brakes soon and i have settled with something abit peculiar but when it all comes together it will be epic!

Although the discs that i will get with the Calipers are going to have a centre diameter of 85mm where the Zed hub bore is only 73mm (IIRC) so they are going to be far too large :(

 

Is there any way to get around this? i have looked at getting custom Disc bell but then the cost saving would be reduced considerably and would be a ball ache. PCD is no isue as i can drill new holes while retaining balence in the disc.

 

Any thoughts are most welcome. by the way the discs will be 350mm x 34mm but that doesnt change anything :P

Could you not have a spacer machined to fill the difference between the discs and the hub?

does it actually matter that the hole is too big? (I dont know)

You would have to use spigot rings, probably big ones lol wouldnt be a great idea but it would work. i would use metal ones so they dont melt although I wouldnt settle for a setup like that anyway, best to have a perfect fit.

Hi,

 

FYI - the centre bore of front (and rear) Z32 discs is in fact 68mm.

 

This is rather a large difference to overcome and if it was me I wouldn't do it - too much of a risk.

 

By the way, what calipers will you be using? Only asking because 34mm thick discs are quite unusual.

 

If you decide to change your mind about the discs and need some alternatives then please let me know. I deal with AP Racing quite a lot and they can sort out floating discs of almost any dimension and off-set.

 

Regards,

well im thinking of going with a Porsche Cayenne (Also VW Toureg and Audi Q7) setup as a set of 6pot callipers and discs are far cheaper than a set of d2 or K sport and they will be just as good (being brembo but im not one for judging due to brand names)

 

Well i have been thinking about it and had a long think about it today and was thinking that if i machine out the centre bell (which is integrated) then make up a new bell which has the correct size bore and drill holes for the correct pcd fitment (as they are 5x130) but we were unsure hot to reattach this new bell to the existing disc (could it be welded on?) as the area around the bell is never used by the pads then i would have some monster discs.

 

I can get a set of callipers (Great Cond.) for 300GBP and i can ask my boss to use the lathe to cut out the integrated bell.

Or do i get he bell out then get one of thos custom floating bells and get that installed (although i dont think i can do that myself)

 

Any ideas guys? How much would a set of floating discs be for 350mmx34mm discs

 

P.s Thanks for the heads up on the bore size. i would have measured but its what i read (somewhere)

With the porsche setup, the 911's can go from the 4 pot brembos to the 6 pot with no problems they just have to bolt on the calipers as the hubs are the same. So realistically i could bolt the big boys straight on with no problems. Disc size will need changing and my brackets will not need changing. TBH those calipers are just overkill you will never get enough heat in them to cause fade, not with an excellent pad and cooling ducts. Ive tried to get mine to fade even with budget pads and they just wont. Stopping from 160 down to 100 is a dream, I cant say the same trying to stop at slow speeds over bumps with such a stiff setup lol....

 

 

actually im not 100% sure if the cayenne calipers are the same as the 911's turbo setup. Il ring my porsche buddy now........

 

 

 

edit, nope cayenne are different oh well lol.

I got my D2's for 635, they do crop up at reasonable prices from time to time!

 

In the interest of keeping the brake bias in check, what are you going to do about your rear brakes munny?

what about rear ones are they straight bolt on too ??

well jimmy that puts a stop on my hunt for some 911 discs :P

 

i could just make some sort of alloy spacer to weld to the existing disc. re-drill some new pcd holes and away i go! will ask a few guys i know what they reckon.

 

Rear will be left for the moment (Holiday in like 6weeks) so im lucky to afford these brakes (if i get them) but the it will be the same setup (Cayenne 4pot calipers and their stock rear discs which are 330x28) which are the same size discs of the d2 front brake kit for the Zeds LOL!
