    should directly swap, but your brakes wont fit, you'll need the s4 ones or brakes from a b6/b7

    Nice one, cheers lads.

    Did you get the brackets on SRS then Kev? Just pipped me at the post! lol.

    Are any Porsche calipers straight bolt on for the S4 hubs or will they need any spacers etc?

    Porch Cayenne (or the equivilent caliper from a touareg or Q7) will more or less bolt on, but you need to mess around a bit with the bolts and disks.

    I bought the brackets yeah, no idea if they'll fit the calipers i'll have but i'm going to give them a try and see.

    What calipers have you got? If no use let me know as im still interested.

    Cool, thought the Cayennes were bolt on, but not sure i wanna go that big, monster 6 pots might be OTT. Just looking to improve for the supercharger when fitted, any other options other than Cayenne? 996TT? 993? Think Boxsters arent worth using, smaller?

    Already have wheels i want to use aswell so dont want massive brakes that wont work with them.

    I've got a pair of Brembos off a Megane 225. Bolt spacing is correct, but offset etc could be totally wrong. I'm hoping i can skim the brackets down if needed, but obviously if material needs added it becomes a bit more difficult!

    I'd tread very carefully there Kev, have seen some stories of named brand adapters failing badly, not sure if its material or heat influences aswell as force inverted on them that cause them to crack or even break chunks of where bolts are used, i wouldnt go the skimming route Check on Audizine. Or look at skimming the caliper if need be.

    Not sure if meganes will work, not seen them used on other cars before, good to know when you try thou, keep us informed

    Yeh i'll be sure to do it properly. The adaptors have plenty of girth, so i dont think it'll be a problem taking a little bit off if needed. If i'm not happy with them i'll sell them on and have a new set made, doesnt usually cost much more than £100 to have a set made up.

    I'm really surprised no-ones used the megane brembos before tbh. They've got perfect sized pistons for the b5, are radial mount so easy to adapt, very slimline so should provide good wheel clearance, are a monoblock design so should be really stiff, and are fairly cheap.

    Where you get them and how much? PM if you want Kev.

    Are the Clio ones the same or they smaller in anyway?

    The adaptors i've got are just those ones off SRS for the porsche calipers. I'll see how they fit, and go from there.

    The calipers were from ebay, cost me £200. Clio ones are the same too, think they're used on the 197/200 clios.

    Yep, the 197 ones i mean, seen the odd set available.

    Whats the deal with Porsche rears, most use them for upgrades on Golfs etc but do you know the piston sizes, are they any use for our cars as i know some dont work out as an upgrade with smaller pistons etc.

    Porsche rears are completely useless, even for a golf.

    Folk that fit them are basically clueless, as even though its a fancy 4 pot, in hydraulic/mechanical terms its the equivalent of fitting an Audi rear caliper to the front of the car.

    996 Fronts are fine for a golf/A3, but the pistons are a bit small for an A4. 996 Turbo or 997 C4S front calipers are better matched to the A4 in hydraulic terms, but they're designed for 34mm thick disks which poses issues with making them work with an off the shelf setup.

    For mine i plan to use a 320mm disk (same size the S4 uses as standard) from an A5 as i feel this will be plenty for the use the car gets, and provides a decent balance between adding huge amounts of extra weight, wheel clearance, and performance.

    Good stuff, get a thread up for them if it works out.

    Well i'll look into the Cayenne setup, but hope it doesnt pose issues with 18" wheels, think a few on SRS have them, maybe ask there for clearance issues etc.
