    When I brought my car it had new standard oem brakes fitted to it . I don’t track mine and occasionally fast road but to be honest the standard brakes on an e46 m3 are shockingly bad for the power it has over the cars I’ve owned previously in my opinion

    Best thing I ever did to my E46 was new genuine discs all round, PFZ performance friction pads and braided hoses.

    You can get the brackets from various places.

    It’s a false economy though as CSL discs won’t give much benefit over the standard size. And the sliding piston calliper will still suffer the same issues.

    I have a set of used genuine CSl carriers (brackets) for sale, saves you importing them or going the dealers.

    Really? I've found them a little crappier now (only when I am pushing the car mind you), but the front discs are below their minimum thickness and the pads have little life left in them.

    When I got the car, the discs and pads were 1 year old with 7k. They seem more than good enough for what I threw at them. Compared to others car I've had, I've found them fine. That also includes Porsche 944 Turbo with the 928GTS/965 'Big Black' brake kit. Over my S1 RS Turbo with Wilwoods, the M3 knocked that setup into a cocked hat.

    I am however running genuine pads and not OE, where on other cars I've noticed a difference between brands and on the M3, I've seen retailers sometimes selling 330Ci items off as them (Delphi stock the same pad for the rears for example for both an M3 and a 330Ci).

    But these cars are now 15+ years old. I'm refurbing a set of CSL calipers and TBH there are signs that they were not working to their full potential.

    Ah another former s1 owner (nice) mine had cosworth disc Alround and thought it was a brilliant set up but weight and drive of the car was completely different to an m3.my m3 set up was all oem discs and pads (2 months old when I got the car, was ok when I got it )2 years later and 6000 miles got serious fade and noise if I been giving it the beens for 10 to 15 mins.just done the F8x conversion new oem discs and brembo pads and so much more to my liking.

    Yup!

    Mine went from a Wilwood conversion to a Cosworth setup. That brake setup with S2 drums on the back was near unstoppable on that car from the Wilwoods. I recall Norris saying it was the best setup to do unless the car was running alot of power (i.e well over 300BHP), and that even then, the setups can become overkill.

    Good to see you got a result with the F80 setup (y).

    I'm staying OEM with mine, but changing the following:
    -Brass slider bushes (even new rubber ones make a big difference IME)
    -Pagid RST1s up front and Pagid RSL29s on the rear
    -Full CSL brake setup

    The discs I have are within spec by quite a way, so I'll be using those until they become too thin :).

    Just ordered oem discs all round. Cotswolds have fronts at £283.95 on eBay and the rears at £225 on eBay. Went to my local dealer who matched price (in fact beat it by £6 lol). So all in £502.49 for discs. I thought that was pretty good when the starting bmw price was £669.92!

    I also ordered the the same from Cotsworld:
    Fronts: £283.95
    Rears: 225

    I then purchased the brake pads from EBC brakes direct - orderd the yellow stuff package which includes (Front, Rear, Braided lines and Fluid)
    I also ordered the front and rear sensors
    Total came to £267.73.

    Now I need to get the pressure sensors -

    Then the car is ready for the garage :muttley:

    EBC Yellow stuff work great with standard discs only issue is they wear the discs out quicker but that's true of any pads that offer increased stopping power. I had Yellow stuff in for a couple of euro road trip (mountain passes and so on) and they were great. I've gone back to standard pads for now but would put some more in if taking the car to the ring or another big road trip.

    The eurocarparts prices are always loads more than you can get them from Cotswold or sytner Coventry.

    I have some Yellow stuffs brand new that I've never fitted that i would sell if your'e interested.

    I'd also buy some

    -New slider bushes ; Bigg Red do these
    -Ceramic brake grease

    These will also improve the braking system.

    Don't put copper grease on the slider bushes ; they are generally designed to be installed dry. If you feel the need to use anything on them, use red rubber grease on the sliding pins.

    Also, prior to fitting them, clean the bores of where the bushes go with a wire brush on a Dremel or similar

    Finally, ensure the pads can truly glide smoothly on the caliper carriers.

    Those few things have really improved marginal brakes on a sliding caliper application for me.
