Another pads and rotors thread

If its a dollar issue, Max at OEMBimmerparts has an axle "kit" for $159.
Akebono ceramic pads, Meyle rotors, and the appropriate sensor. Front axle or rear axle.

I guessed wrong, and replaced the rears. Light actually was for the front sensor. Parts will be here Wed or Thurs. . .

Yes, and remember that you don't want to use the minimum thickness. Obviously, they are useless at that point.

Go to Bmaparts.com and get the OpParts brand rotors and ceramic pads. I did the front rotors, pads and the sensor for $98. 15k miles later still going strong and vibration free. Not to mention the ceramic pads are extremely low dust. And of course, always excellent customer service with bmaparts and super quick shipping. Not affiliated with them but a very happy repeat customer.

The minimum thickness is there to let you know when the end of life of the rotor has been reached. Provided there isn't excessive rust, scoring/cracking and the rotor is true with sufficient meat on it; running them to the minimum is fine. Once a rotor gets to this point however, it MUST be replaced.

which one is Better......Drilled Rotors?...or Cross Drilled and Slotted?>>.
as far as preventing warpness cracks...etc.....everyone has there own opinion ..but let me hear it guys...

[Ricky Bobby]

supposedly if the cross drills are done right they are structurally sound, most people have problems with rotors cracking from bad work on the cross drills.


I highly recommend www.adamsrotors.com for quality work that is done custom as you want it, and honestly i don't think their prices are too bad. I had their brakes when I upgraded my old VW, and the quality and look was great.


People are going to tell you that cross drilling technically decreases surface area of the rotor and can in theory keep stopping distance the same or increased. I've always been under the assumption that slotted rotors will be a bit noisier than blank ones, and cross drilled is mainly for looks.


My true opinion? Unless you are doing a true BBK, if you are just replacing with OEM sizes, get OEM rotors, blank, with some sort of protective coating on the hub and outer surfaces to prevent rust, get good ceramic or higher performance brake pads, and do a flush with quality performance fluid and you'll have all the "performance" you could want.

All this rotor-talk is complete rubbish. I've got OEM blanks, carbotech AX6, SS Lines, and ATE Blue. The combination is actually too powerful for the factory tires. As soon as I get some heat into those pads and I do a slightly harder than medium stop, the ABS goes insane. The braking force actually overwhelms the grip of the tires. Next time around, I'm stepping back down to carbotech 1521 and better tires.

The only way to genuinely get better braking performance is to get better tires and better pads. If you want even more braking power, you have no choice but to get a big brake kit as the big brake is about the only thing that will actually help your ABS kick in much later and work better when it does, in fact, kick in. Rotors ain't gunna do anything (unless they're some cheaply made $15 rotors; in which case they'll be worse).

This.

I recommend the same. The OpParts brand has black hats.
