Talking Rotors Rubbing on Calipers

So i just installed some new Zimmerman Rotors on my e90 2007 328i, and I found that the rotors are rubbing on my calipers as I am driving. If anyone has any idea why this happens or has a solution please let me know.

The only SOLUTION that i came up with is riding without the anti-rattle clip. Im not sure if i need this one but since it came with the brake system, i'm assuming it is a necessity!

Anti-rattle clip won't cause that.

You have the wrong rotors, did you put 335 rotors on instead of 328?

I bought the "BMW Brake Kit - Zimmermann/Akebono 34116855006KTF2" from FCP EURO and it says it fits a 2007 328i

Did you physically compare both rotor sizes first to confirm the parts are matching.

What is your E90's production date? It says that kit is for E90s with a build date starting with 09/2007, which is 2008 model year.

Very strange but I think you might need 300mm rotors and got 312mm rotors. I don't think the aluminum finned calipers pictured came on 312mm set ups that are usually on a 328 - only 300mm or 330mm.

Check your actual caliper for specs - the last 3 digits specifies rotor diameter. Eg 57/24/300 on this caliper = 300mm rotor:

I was reading the top and I concur here. IIRC, the LCIs had the 312x24, you have an earlier model. That's your issue. Call up FCP and tell them their fitment messed your brakes up -- they might swap them out for you.

I'm surprised the caliper actually fit over the discs. There's not usually that much room but not having the spring attached also allows the caliper to twist inside the rubber guide pin bushes as they are the only things left holding the caliper to the carrier
