Needing front pads...
I'm coming up on needing new front brake pads for my 135 in less then 700 miles. I've been reading up on some various threads about stock OE pads vs. aftermarket such as Hawk, Cool Carbon, Fedoro, etc.. My car is pretty much strictly a street car and I haven't taken it to a track so I don't need anything too crazy. Just looking for something with lower brake dust then OE but still have a good bite and feel to the pads. Also need new sensors and read that the Fedoro don't have any room for the sensors. Any advice would help.

No aftermarket pad will have the same initial bite as OEM pads.
If you want something that has a bit better performance with significantly less dust than OEM then Cool Carbons may be the way to go. Less initial bite but with considerably less dust, higher friction coefficient and higher operating temperature. DS2500s have better performance than cool carbons but will also dust the same as OEM pads. Those are probably your best options. EBC redstuff pads are another option but probably similar or slightly better performance to stock with maybe slightly less dust.

I run redstuff pads. Way less dust than stock, but not dustless. Great bite too. The only downside is that they take a while to break in and stop squeaking .. took about 1000 miles on my car. They are supposedly also harder on rotors, but I have no point of reference. My car is closing in on 39k, and I'll replace the rotors next time I do brakes. I like them well enough that I'd run them again, though I may try cool carbons next. Ferodos dust at least as much as the stockers, which is a lot. I have a set I use for the track.
Out of all the pads I've run over the years, nothing dusts less then Akebono Euros, but the initial bite sucks. Ultimate stopping power is good, but you have to be careful while you adjust to the additional pedal pressure required to make the car stop. |

I have the Cool Carbon and also like them. Significantly less dust than the stock pads (but not zero) and easier to clean off. The initial bite is a bit less, and the pedal travel is a bit more, but I like it as it makes modulation easier and you can come to a smooth stop under light braking. They get better as you get temperature in them, but can make a little noise when hot. I put in OEM wear sensors when I replaced the pads and regret it. I thought my first set were just bad due to squeeking/dragging but my new OEM sensors are already doing the same thing.

I have read that the brake squeal can actually come from the rotors when a lip forms. |

I considered this and checked the rotors and they seemed fine for the time being. The noise definitely went away for a few thousand miles after the new pads/sensors so I wouldn't think it could be rotors, but I could be wrong. Maybe someone with more info could chime in.

I had the pads changed with another set of OEM pads after they wore down at around 60,000kms and it was quiet as a mouse for a while. Some squeal has returned however nowhere near as bad as the first set and I don't need to flush the pads with a hose everytime I was either. I'm on my original rotors and I'm now at 109,000kms. There has been a significant lip formed but obviously wasn't there when I bought it. I guess it could be the brake sensor but I wouldn't think so as it should only be plastic touching the rotor surface until it wears down all the way to the metal contact. My guess would be that it's just due to the pad material itself and my first set was probably a super bad batch of material. All 135i's on stock pads squeal, some more than others. I have an E82 135i as well now with 38,000kms and it also does it, though nowhere near as my initial set of pads on the E88. |

half the price of all other options... and actually they'll be a LOT better than stock, the greenstuff are EBC's 'stock replacement+' pads, redstuff are fast street, yellowstuff are track |

I ended up getting Cool Carbon's but I haven't had a chance to put them on. Had them sitting in my garage for like a year... |

they apparently will wear through rotors a fair bit more than OEM, which is probably a by-produt of being less dusty and more grippy.. no one should be worried about that as it's still 1-2 years of driving minimum for 99% of people i've used them on other cars and they bite well and handle heat well. still on stock pads? i'm just incredibly tired of their dustiness |

Yeah I'm on stock pads and they suck balls. The only reason I haven't installed the Cool Carbons is because I have a full BMWP kit with slotted/drilled rotors, SS brake lines, F30 backing plates, titanium shims and Castrol SRF Fluid waiting to be installed at the same time and I haven't gotten around to it. That and it would be the first time I've ever done any kind of install/maintenance/service on the brakes of a car lol... Have you bought a full 135i brakes kit already? |

yeah i'd like some hawk HPS going by internet opinions but too many dollars yeah i've got the calipers, front rotors, fresh mounting hardware - the rears fit a 130i with 135i hub flanges (10mm wider), same handbrake shoe. lucky lol. what's the deal with the ti shims? i've only heard about them in the last 1-2 days... neccessary? it cost me $1000ish for the 135i parts inc shipping... and i still have $1k+ in parts to go, considering i'd like a set of solid pistons in case the stock ones go bust with some track time... and i'm getting them powdercoated black... so it may 'only' be $130~ more for the cool carbons... but it all adds up sadly haha |

Ti shims help to reduce heat going into the caliper so basically it helps to preserve the stock pistons and reduces heat transfer into your brake fluid. Also would help stop your calipers from overheating and changing colour. |

Of course some additional cooling would be beneficial with or without Ti shims. Ducting or F30 backing plates would be in order.

Ferodo DS2500 is a clubsport pad and will dust more than OE with no sensor cut out. |
