    Hi chaps,

    I have a complete M3 that I've got in that's being broken and I'm wondering if it would be worth swapping over the bakes on it and if it is worth the agro or not?
    Is there much of a difference? I know the M3 has floating front discs and are more expensive to replace but would I see a noticeable difference in stopping power?

    If its the same as the E46, M3 discs are bigger. Bigger discs make better stopping power. I can certainly tell the difference between my 325 and the M3, both came with OEM pads/discs.

    Is it worth it? It's up to you. If you're not happy with your brakes as they are then yes change them. I upgraded the discs/pads on my old scenic because I used to carry a lot of weight in the car (well the missus) and often found I suffered from brake fade....upgraded to EBC drilled and grooved with better pads and this became a thing of the past.

    Is it an EVO?
    i fitted the 3.0 setup to my M52'd 318iS and for the brief time i have driven it i was quite pleased with the performance i will need to get it on a good run to see how they perform but i did realise that it beats the ABS, it still manages to lock up the fronts a wee bit inbetween the brakes going on and off rapidly, when the pedal is kicking back
    however i do have braided hoses all round and grooved discs with greenstuff pads on the front
    you will need the front hubs and the front struts
    if you use the standard E36 front strut it will move the front wheels towards the front bumper, i had this problem so i just fitted M3 suspension and the wheels went back to the correct position

    EDIT: the stanard 328i discs are either 286mm or 288mm diameter on the front and the rears are 280mm
    the M3 discs (3.0) are 315mm on the front and 312mm on the rear and the calipers are bigger, i have soem pics somewhere ill dig them up and post them

    Thanks Disco and yup its a 3.2 EVO. The front struts I just replace with Bilsteins so I'm reluctant to swap them out for the used M3 stuff maybe.

    Are the M3 calipers 2 pot or single pot like the 328i?

    they are single pot sliding calipers, just the same as the 328i ones just with a bigger piston
    with the M3 hubs there is the oppertunity to fit the 4 pots from an E31 8 series

    for the benefit of others, ive seen on here and other forums that if you carry out this conversion the you will need the M3 master cylinder
    i still have the 318iS master cylinder fitted and the pedal didnt feel too bad although further testing (giggity ) will have to be carried out to acertain the pedal feel etc
