    you can also use cayenne, q7, touareg 6 pots on the front. The 17zr/l's work better because of the piston sizes and adapters are £70 from lee (cnc-machinist from r32oc/jack-the-lad-uk on ebay. just got mine from him and could not be happier, really helpful guy and very very good product. work with r32 discs or 350x32 ecs'. My calipers are off for painting but will get pics when ive got them back.
    And if you are after different adapters im sure lee would be up for a challange and cheaper than most :)

    ICE; the above combination is what a lot of people have gone for, that don't want bigger calipers.

    I will be going for them as soon as I get my arse in gear.

    Hey ice, I had the Black Diamond Grooved/DS2500 set up prior to fitting Brembo's and they done a great job stopping the S when needed, they didn’t squeak or create any more dust that was noticeable. I ran them for well over a year , maybe more can't remember for sure before selling them on.

    Best way to sum them up would be a great cost effective way of improving oem brake feel and look without blowing the budget.

    what brakes do you have now Maz? Are they LCR brembos? Have you noticed an increase in breaking performance?

    I've got the GT Kit (grooved discs and Brembo pads, will change to DS2500 pads again when need be.

    For sure, they are sh't hot and do the job with ease, I'm a safe driver majority of the time but when I have a funny half hour or so they give you the confidence to drive hard without fear.

    Yeah, i managed to get some LCR bremos of ebay. Calipers, carriers, disks and pads included. Disks look pretty rusty compared to the picture shown though. They need to be skimmed, not sure what pads ive got :)

    I know the ones you've bought (you little bugger ;)).

    I still wonder about this as there are a few going on eBay. What are you going to do - buy new discs and pads?

    Hi,

    Can anyone confirm that a3 quattro rear calipers are actually different to the rest of the mk4 platform? As first thread says needs 6mm spacer.

    I have a quattro that needs a new rear caliper but theres no point buying a mk4 caliper if they wont fit!

    Cheers

    same as R32 brakes.

    They will work, but they're incredibly heavy, and still an ancient sliding caliper design.

    Also, replacement discs are mega monies.....

    Yep they work fine, and to the below yes they may be old and have expensive replacements but i got my kit for £250 including almost new discs and sold my old 312mm set up with almost worn out discs for £230 over all one hell of an upgrade for £20 they are worth £250 all day imo even on an r32 the discs are good for 50k. i couldnt recommend the upgrade enough :)

    Great thanks, I got the whole set up with brand new disks and pads for £300 which I thought was pretty good :) just one of the bolts was missing so that's a relif to know I can use one of the originals! I seem to have misplaced one of metal clips are these easy to get hold of?

    does the front to rear brake bias need adjusting when sticking big brakes up front?

    I have a few spares if you need them give me a shout but mine were identical, metal clips? as in the pad carriers? Just a little word of warning the r32 pads dont have a ware sensor so you will have to cut your old one off the and solder it up and stick it back on.

    That would be overkill for rear brake bias, even my ECS stage 1 rears, 308mm is overkill, but it looks good!

    You could run 2 rear discs made of cardboard and you wouldn't notice a performance drop as they hardly do anything. It's all about the looks.

    Thanks Jojo.

    Back of the envelope number scrawling suggests that upgrading the fronts to the LCR brembos is an 86% increase in breaking effectiveness and changing the rears to the fronts is in fact a 146% increase in breaking effectiveness, and thats ignoring any change in pad area (because i dont know them). Does that sound about right?

    A little overkill! Not a great idea then

    EDIT:

    Right, so leaving the rears as standard would seem more sensible. Considering a standard front to rear brake bias of 60/40 upgrading the front barking effectiveness by 86% would change the front to rear bias from 60/40 to 74/26. Does that sound right?
