The front callipers go on pretty straightforward with just a simple adapter has to be machined.

















The rear are a bit tricky as you have to modify the rear calliper slightley on the machine in order to have perfect aligment of the pads to the discs.



Here are photos from 2 sets being made to fir the E46 M3.

Photos are from my local company Milletech that build awsome exhaust systems for some top cars.

Hello,

Sorry for the late reply... here are some photos from my car,








Did some miles and a track day and it works perfectly! Love the brake feel and compared to the old setup with PFC and Endless pads it is night and day difference.

I was concered about the rear end being to strong but I got a recomendation from endless to use a slightley less grade pad at the rear and the car just feels so stable at hard braking.

I haven't looked into the M4 brake setup that far but how's the brake bias for the E46?

Looks aesthetically pleasing though!

Used to have nice gold STI brembos on the Subaru, upgrade to a BMW M3 and get zero brake bling, thanks BMW (they do stop better than STI).

Good looking calipers.

Now that this is being proven as a possible upgrade, i'm definitely interested vs installing 996 brembo calipers. Keeping OEM BMW pads is a huge plus for me.

Thats is the reason I did it as I can switch between my m4 easily and all the parts I need are on stock at the dealer.

Only downside of this upgrade is the rear OEM M4/M2 calliper has to be modifeid a bit.

Don't want to say anything definitive without seeing numbers, but my gut says two cars with similar weights, weight distributions, and same engine/drive layouts are likely to have similar brake biases.

Is Milletech selling the brake adapters?

I can get them for you if you are interested as I have mine now and no further measurments are needed, that is only if used with OEM M4 front and rear discs.

As I said the rear calliper has to be modified a bit, which is straight forward, i can take some picture this week and share it with you.
