Rotors

another question concerning my bimmer... i think its time to replace my rotors, but im not too sure because they look perfectly fine. i cant see that they're warped or wearing or anything. anyway... im still convinced its my rotors because everytime i brake at fairly high speeds (highway mostly) my steering wheel shudders around like crazy..

so i looked at some rotors online and i saw the regular disc brakes (which i have now) cross drilled and slotted. i have no idea of the difference btwn these 3. but if i do decide to get either the drilled or slotted can i only have them on my front brakes and not my rear? (since ill still have regular disc brakes on the rear)

whew. bimmers can be money pits, but they def. are worthit lol

thanks!

Well, I haven't put drilled/slotted rotors on my Beamer yet, but I did have drilled and slotted rotors on my Integra at all 4 corners. They were the best. Never experienced brake fade after that... Now you do need to be aware that you can't "turn" drilled or slotted rotors. If they warp, you are done. You would need to purchase new rotors. You may be able to get away with having your current rotors turned. If you can, take one off and take it to a machine shop and ask the machinist if he can "turn" them. He should check to make sure they aren't too thin and then you will know your answer.

Good luck,
Paco

Really? I thought for sure they would help. I know that the front brakes have air directed to them to cool them off faster, maybe that is why. since the drilled/slotted rotors are designed to dissipate heat faster...

Drilled have holes, slots have slots. People can argue back and forth over which one is better, but for street the rotors won't make a difference. If you plan on tracking your car or doing other forms of extended "spirited" driving then they can help reduce brake fad and should be matched with non-oem pads for the best effect.

Good post.


The arguement has always been made as to which is better. Slotted eat away at your pads quicker because the "slots" slice off a layer essentiall each time you push down the pedal.

Yes you can put x-driller or slotted at the frotn and not the rear. The advantages from them are minimal on the street besides their appearance.

How many miles does your vehicle have? Why are you so sure it's not something suspension related like control arms?

Do this quick check.

Stand on the side of your car observing the front wheel. Have a friend drive the car slowly then slam th brakes. 1-3 mph. if you notice the wheel shakes a little bit it's very possible your control arms are the problem.

Also could be your wheel hub/bearings or even a missing or worn sway bar link.

hmm, i didnt consider all that. but im pretty sure they're my rotors, because whenever i brake at high speeds it'll shudder. if im going slow i can hit the brakes as hard as i want and i wont feel a thing shudder wise. my car has about 124,000 on it. but yeah that makes sense, i dont do any track driving. i mean ill drive my car hard here and there but i dont think its enough to make use of slotted or drilled rotors. but i do like the appearance, so paying the extra couple of bucks for appearance might be alright with me.. but thanks a lot guys, i learn something new everyday..

^^ I may be wrong, but to me the fact that you only get shimmies at higher speeds points not to the rotors, but to suspension components

my bro's 318 did the exact same thing. His rotors were warped like crazy.

i recently got new gas slotted rotors on my 323is and some axxis pads. o and alos new barings. and my car stops like a dream.

it sounds like you need new rotors but thats just my opinion (it could be anything)

When I had warped rotors I could feel "pulsating" while braking, regardless of speed. I also know a guy with brand new brakes and shimmies. He's looking at a new wheel hub. Just saying.

wait, drz, are you saying like... my rim itself might be bent? bc ive heard that happening to bmw's, which i heard was a fortune. i dont know... i guess my best bet is to just let someone look at it, that'd be the safest way. and i really hope its not any suspension work, i dont have the slightest clue of that either lol.

and thanks for the website, ive never come across it before. and the prices for rotors are slightly less than what ive been looking at.
