no, it won't fit. it's only meant for e90.

does it mean that it's impossible? no, others have gotten it to fit by getting custom brackets made. but i still don't see why you'd want to do that considering these brakes weren't meant for the e46 so you're messing with brake bias.

best to wait and find something on classifieds, i've seen stoptechs for 1200 in the past.

This correct, it would not fit the brackets would not match.

E8X?, they are 135i brakes IIRC. Tischer was selling a 6/4 kit for 1500 some time ago. Bias, a front brake upgrade only doesnt make much sense.

OEM BMW E46 rotors are not a floating rotor, front or rear. PFB, as mentioned, makes true floating OEM replacement.

OEM BMW E46 rotors are not a floating rotor, front or rear. PFB, as mentioned, makes true floating OEM replacement.
per the BMW M department, these are floating...

Suitable for street, track, or race use. The "floating" design separates the central rotor hat from the outer disk, allowing the disk to expand radially with heat and limiting heat transfer to the hub. The theory is that the rotor will not "cup" or distort under extremely hot race use, resulting in better braking performance and better rotor and pad wear. Additional benefits include lighter weight, approximately 1.5lbs per rotor.

BMW Motorsport uses a "radial floating" design where the floating connectors between the rotor hat and the rotor disk connect in the center of the disk between the inside and outside face planes using a radial (straight out) pin. It's a very interesting construction that is not simply "assembled" but built all together at the foundry level.

They are not the standard OEM rotors, they are more like BMW Performance Aftermarket rotors, like M5 OEM.

gotcha, was thinking more of the two piece design, that allows you to replace the disc separate from the hat. Not sure how well and if at all those standoffs work though. 2 piece designs allow some movement when the disc heats up.

Just ordered mine this afternoon!!!! Just when I thought I was going to have to go with zimmerman or something else, since all of the other sponsors seem to have upped their prices back to list on these. Thank you ECS and littlebear for bringing my attention to this.

Most people are going with HAWK Ceramic Compound Performance Pads

The ultimate stopping power in an ultra-low dust low noise ceramic compound!

Hawk Performance has introduced a premium high performance ultra-low dust low noise compound called Performance Ceramic.

Performance Ceramic is engineered to reduce brake NVH (Noise Vibration and Harshness) creating a quieter performing brake pad.

Furthermore the ceramic brake pad formula has a linear friction profile that allows your ABS brake system to work more effectively.

With Performance Ceramic you can expect reduced brake pad wear lower dust output levels and a rotor-friendly brake pad.

* Ultra-low dust
* Improved braking over OE
* Stable friction output
* Extremely quiet
* Extended pad life
* Increased rotor life

Click HERE for more information.


Please let us know if you have any questions! Feel free to shoot me a PM or email.

Best,
Joe
