Subscribing as I am also interested. I have used Zimmerman rotors on all my other BMWs except the 1M. On the E46, they worked great. I did learn a valuable lesson one time with my Subaru Legacy GT Wagon in 2002. The car had very good brakes but the rotors would warp. I loved the initial bite and cold characteristics of the Subaru pads just didn't want the rotors to warp. I ordered a brand new set of Subaru Original pads but Brembo rotors from Tire Rack. When I changed out the rotors, I noticed the Brembos were lighter than the worn Subaru rotors which I thought...cool, lighter rotors, more performance. I changed all 4 rotors again with factory Pads. At first the brakes had no bite, but I just figured ok, I replaced all 4, they just need to bed. But I drove my wagon brand new and the brakes were excellent brand new. They got a little better after about 200 miles but there was no bite. I drove another 300 miles and still no bite. I thought I did something wrong, so I went back to Subaru and got another set of front pads. Drove another 1000 miles and while not unsafe, I no longer had the awesome brakes my car came with. I was puzzled. It bothered me quite a bit. I went back to Subaru and bought a pair of Subaru rotors and put them on with the Subaru pads....boom! Instant bite back. I went back and bought the rears Subarus and again reused the pads. Brakes went right back to the way it was new.
The point is, that something in Brembo metal composition did not work well with the factory Subaru pads. Maybe if I used Brembo pads, things would've been different. So from that point, Zimmerman is the only non BMW rotor I use and have not had a single issue. I tried ATE uncoated rotors in my E46 325i and they worked well also but rusted up something fierce and looked terrible behind my BBS RXs so I switched them to Zimmerman coated. So I expect Zimmerman to work just as well as BMW OE but I have seen non-OE rotors not work as well with OE pads. They are designed to work as a unit. I can't wait for feedback on this thread. Personally I drive the 1M so little that for an extra $100 a set, would get OE BMW but if you drive a lot, the lower price makes sense. Thanks for posting! |

Thanks for the response. The juan is my daily driver and i drive it pretty hard. I read a lot of mixed reviews that zimmerman tend to warp that's why I wanted some 1m owners opinions on that. I could get the zimmerman 250 CAD cheaper which is not a big deal. But ultimately i dont need any warping issues anytime soon. I wouldn't be happy at all about that so Im slowly opting toward the oems.
are there any other alternatives that are perhaps slotted not drilled? Even if it costs a bit more than oem? |

Apparently Stoptech has some replacement rotors:
https://www.m3post.com/forums/showthread.php?t=1251029 ECS also sells a house brand: https://www.ecstuning.com/b-ecs-part...01004ecs01akt/ PFC also has a V3 Direct Drive replacement rotor for the front. https://www.m3post.com/forums/showthread.php?t=1330681 I don't know if the PFC V3s are slotted or dimpled -- the V2s were dimpled and I had no problems when I was running the V2s other than a whirring sound at speed, likely caused by the dimple pattern.

The reason I was asking was because I get a lot of mixed reviews on the net , many claim that Zimmerman are garbage and easily warp :/

1M Manual link below ://www.1addicts.com/forums/attachment.php?attachmentid=1305123&d=1445515421 Finally, on Textar pads, I am a big fan of them. Alway had great luck with them. They tend to have great cold bite, which is high on my list but they also tend to be slightly noisier and can you have to be more diligent installing them. Make sure you use some BMW brake paste on all metal to metal contacts on the pads including the pad backs. The paste is less than $2 at the dealer. Jurid pads are generally quieter but don't have outstanding initial cold bite. Once warm, they work the same but when I'm driving around in the morning in a cold car and a kid runs in front of my car, the extra 5 feet it might take for the pads to bite can make the difference between "damn kid where are your parents" and OMG!
