#2. Warped Rotors -- Improving the situation? - from Paul Elliott

Date: Fri, 22 Feb 2002 19:44:45 -0500 From: "Paul Elliott" <elliott.paul@worldnet.att.net> Subject: Warped Rotors -- Improving the situation? Peter, >>The question I have to ask is, what am I doing wrong? << On your last street warpage, have you confirmed that they are warped via runout gauge, or are you assuming theyre warped because of a vibration yourve picked up of the steering wheel during braking ? The folks at Kline told me that they think its very hard to warp rotors on the street...Even with the most aggressive street driving, the conditions dont come close to a track situation. I described my situation to them which I thought was warpage too...In mine the degree of vibration seems to come and go...Sometimes its pronounced; other times, its minimal, each time measured from 60 to 70 mph.. They thought it was more likely the pads, having transferred material to the rotors, are causing less vibration as the material wears off, and more as its deposited. Anyway, Im going to try a new set of pads first...Im currently using something called Rotex, but Ive experienced this vibration problem now on two different sets of rotors each time using Rotex pads..Im going to try probably the Hawk street pads, after applying some light sanding to the rotor surfaces, and see if it makes a difference...If it does, great...If not, I'll have to try a new set of rotors too. But Im guessing its the pads in my case.

The thing I have always found to be crazy, given the usual German attention to detail is the valet key. It will not unlock the trunk (key won't fit), but when you unlock the door, the trunk unlocks. Not to mention that once in the car, you simply fold down the rear seat for access to the trunk. Go figure. Ken Dobyns Portland, OR '98 M3

Jeff, >>According to some, there is no such thing as warped rotors, but rather, uneven deposition of transfer compound on the rotors.<< Great article! Thanks much....The guys at TC Kline have told me as much, but this verifies it....What I earlier thought might be warpage in my second set of rotors on my '99 Im pretty sure now is the transfer of my Rotex pad material...Im going to try a new set of Hawk street pads first, and if their use doesnt remove the material, I'll have to try some new rotors. Thanks again.

You can use the regular key to turn the trunk lock 90 degrees clockwise and pull the key out (so that the slit is horizontal). Now you can unlock/lock the doors to your heart's content and the trunk will stay closed. You see...vallet key...how will they get into the trunk? Now, yes...you can get in through the split folding seats, but some cars didn't come with that (4 doors) and I think the most important thing (sometimes) is the spare wheel and people stealing that. Try taking that wheel out through the split folding seats ;) Chester > The thing I have always found to be crazy, given the usual German > attention to detail is the valet key.

That's exactly what happened to my Euro floating rotors: stock pads in front and PBR Deluxe in back (don't ask ;) Warped the Euro's with just street driving. Installed Pagid street pads all around with new Brembos up front, and all's been fine. Nick > We had a guy down here in San Diego that was warping rotors at the same pace > as you.

It was the front control arm bushings! Several sources suggested them and even after removing them, I couldn't tell visually that they were worn out. I replaced them with a set of Powerflex bushings and now braking is very smooth. I had 75k miles on my car when I replaced them. and I also discovered that the stock bushings go as quick as 30k miles - even on e46 cars. If changing pads and sanding off the rotor deposits doesn't change things, I would suggest you look at the bushings. - Bob -----Original Message----- From: Paul Elliott [mailto:elliott.paul@worldnet.att.net] Sent: Friday, February 22, 2002 4:48 PM To: E36M3 Subject: [E36M3] Warped Rotors -- Improving the situation?

Thanks Bob...I still think its the pads/rotors because about a year ago, I experienced the same symptoms, and at that point I changed both pads and rotors, and the symptoms disappeared, for a few mos anyway...But since the symptoms are similar I really dont know....I think I'll partake in first trying new pads...If they alone wont do it because the friction deposits have changed into cementite (see article referenced in the digest ), then I'll try new rotors....If together they dont do it, then onto the bushings....Luckily, none of these is too expensive to prevent trying all three if need be.

#9. Anyone with 17x9's all around? - from Rob

Date: Sat, 23 Feb 2002 23:58:09 -0700 From: "Rob" <motor@cadvision.com> Subject: Anyone with 17x9's all around? I know some of you guys run 17x9's on your cars. I just bought a set of 17x9" et32mm wheels and I am trying to predict what type of tire rubbing issues I will have when I install them. My plan is to run 245/40/17's all around and I have approx -2.5deg of camber F & R. Any first hand experience with a combo like this? Do the rear lips need to be rolled much? Will the tire/wheel be too close to the muffler? I have previously run 17x8.5" et37 with no issues, but I am adding 1/2" in rim width and pushing the offset out another 5mm! TIA, Rob

Last October at Watkins Glen was the first time I thought I had warped my rotors. On the way home I had a horroble vibration every time I touched the brakes. I was sure my rotors were toast but I had heard about pad deposits and hoped that was the problem. On the drive home I braked hard at every opportunity to try to smooth them out, figuring that if they were warped I couldn't hurt anything and if it was pad material I might clean it up some. By the time I made it home to Saratoga, they were almost as smooth as before the track and within a week they were back to normal. I'm still running stock BMW pads with no problem on the track or street.
