Carbotech Brake Pads
I couldn't handle the excessive amount of brake dust the stock pads create so I spent some time researching low dust alternatives. I settled on Carbotech's street pads. They've been out for awhile and the M5 crowd seem to recommend. them.
First off, this was the easiest brake job I've ever done. It took all of 15 minutes per side to do, and that included jacking the car up, removing the rims and cleaning the calipers. The only thing that took a little extra time were the rear brake tension brackets. Getting them re-seated took a few minutes, but overall, it was really simple. The whole job took me several hours though since I took the opportunity to clean the wheel wells and do a full detail of the rims (power wash, boar hair brush cleaning, wipe down), and then finished up with Adam's Polishes Spray wax. One interesting find was that the inside of the wheel wells are stamped with M2 logos. It rained after doing this so I haven't even had a chance to bed the pads. I did the brake job and then rolled the car back into the garage. It's supposed to be nice tomorrow so I'll take it out, bed in the pads, and drive them for a bit and then give my impressions. Total cost was around $450.

I'm interested in how they work out for you. I've heard mixed things about the 1521s. Especially interested in how the initial bite is and in the cold / rain.

Actually, I noticed on reverse the rears did rattle initially. I took off the rims and reseated the pads and it seemed to have fixed it. The pins needed to be removed and reinstalled. Luckily it's a quick fix.

The car is my summer, nice weather vehicle, so it won't be seeing much inclement weather. I know that on my E46, the issue with my low-dust pads (Cool Carbon) during the winter is when the roads are salted and it snowing out, initial bite is non-existent to the point of being scary. It can take more than 2 seconds for the brakes to grab. In the rain, they are fine.

I ran Carbo 12's on my Evo X with DBA rotors. It was an outstanding setup. I think 12's will be perfect on the M2C as well. I'll make sure I shim them like before. it cuts down on the squeeling...

Cant hammer in the pin - as it hits the pad "ear". I tried a bit force and started chipping off some material of the pad (by the ear). Did you have the same problem? Am I missing something? |

I am not sure I understand. The pistons are pushed as far into the caliper as they can be. So i have tons of space to move the pads towards the "front" sort of speak. Still the pin wont allign the pad into the caliper - at least not as easy and seamlessly as the fronts.

They should fit by moving the pad side to side & in/out within the caliper. There should be excess play due to Carbotech not having the backing plates that are on the OE pads. |

One thing you can try is pull the OE pad off and put it back to back with the Carbo pad to see how the holes match up. |

Thinking about switching OEM pads to 1521's as I cannot stand washing my wheels weekly. Any recent updates on this product?
