    wish I live in US, easy to find tons of aftermarket parts...
    what is front setup? if you dont mind
    talk about bias, how many % front bias you need to attempt?
    here the link to calculate brake bias

    and e30 factory spec
    SPECIFICATIONS SALES FIGURES PRICING COLORS 318i (1984-1985) ENGINE/TRANSMISSIONM10 1766cc SOHC chain-driven inline 4, 2 valves/cylinder, cast crankshaft101 hp @ 5800 RPM103 lb-ft torque @ 4500 RPM…


    Mine with e46 325i brake setup all corners and e28/e30m3 MC (23.81/23.81mm bore diameter, non stepped cylinder) will be around 64% front and 36% rear
    Stock e30 around 55% : 45% (MC size 22.20/17.46mm)
    Stock e30m3 around 66% : 34% (MC size 23.81/23.81mm)
    Stock e36m3 around 60% : 40% (MC size 25.40/20.64mm)

    Could be wrong those number.. I'm studying brake setup now, pardon for not correct one.. and have nice weekend guys

      Stock m3 is about 66/34. I'm actually going to keep it close to that.
      Front will be a 57mm caliper off an e28 535i with 300x25mm rotors. Bias is like 66.2%/33.8%. It is nearly identical to stock

        So, front will use e28 535i single piston and rear using wilwood 4 pistons?
        Correct me if I'm wrong

          update...
          fitting with hub, rotor and caliper...
          sorry if I used right caliper instead left one

            Correct me if I'm wrong
            Correct, I have some design constraints.

            1. Bigger brakes
            2. Good clearance for a plethora of wheels.
            3. Good pad options
            4. Cheap consumables

            E30 m3 front strut housings have a horrible low offset so unless you want to run spacers with high offset wheels or race wheels it makes it hard to justify a 4 piston setup up front. Utilizing the e28 535i caliper allows for a larger piston, same clearance for wheels, and the reuse of your current pads. Pads are readily available for these pistons in many different friction sets.

            The rear of an e30 m3 setup has a lot of clearance for a caliper. Doing the math, a 4 piston setup will allow more clearance than the stock single piston setup. So in the rear you get the benefit of a 4 piston setup, thick pads, and potentially less weight.

            The final bias calculation I have when you factor in pad height, rotor height, piston, and single diameter mc, is 66.27%/33.73% f/r for the upgraded brakes. The stock e30 m3 I calculated at 66.15%/33.85% f/r which is a smig over a tenth of a percentage difference.

              what rotors 300x25mm is that?
              My opinion, instead of wilwood on rear end... why don't consider to use e90 320i calipers?
              Brake bias around 66%/34% almost stock, with single diameter MC
              and also OEM all corners
              If you consider weight reduction on rear unsprung, then keep it that way..

                I'll keep the rotor a secret for now...

                I'm not sure the piston size of the 320i caliper. We never got them here in the US, but I see 40mm or 42mm. If they are 40mm I'd just use an e36 m3 caliper most likely. They are cheap and easy to get. The wilwoods I'm looking at are $155 each and the pad fits perfectly on the rotor. You're also getting the benefit of a fixed vs sliding caliper, but that's kind of moot considering the front is still sliding.

                  Yes, e90 320i is 40mm piston diameter..
                  E36m3 also 40mm..

                  What is the benefit of fixed caliper anyway?

                    More even pressure, even pad wear, can be lighter but depends on what is being replaced, stiffer because the caliper doesn't move, and better pedal feel are the general perks. Oh and swap pads without removing caliper.

                    Disadvantages is they can be hard to fit on a car, but that's on a per car basis, can be expensive to purchase and require adapters. Can be heavier depending on the application.

                      Interesting, I will use fixed caliper if I live in there...
                      E46 325i here pretty easy to find the consumables (pads and rotors)
                      and cheaper than e30 pads and rotors

                      300x25mm secret rotors is Ford Focus rotors? just guess, lol

                        Nope, not a Ford Focus rotor. You have to run a spacer under the rotor to make it fit most likely. I also don't think the hub will fit under the rotor hat.

                          Ups.. I was wrong...
                          Is it 2 pcs rotors with hat and rotor?
                          Yes, we need a spacer if using Focus rotors

                          Auww man.. You made me so corious with the rotors, lol

                              Man I am so fucking pissed right now... all this comes out only a few months after I made brackets to get e46 brakes to fit on z3 hubs.... make a kit, people will be happy & definitely buy
