In a pickle: what rotors for 135i rear caliper on e91.

Happy Easter

So I bought all 135i brake parts to retrofit on my 328i wagon, and I missed that the rotor offset is different on the 135i rears. So now my daily is on blocks in my garage until I figure out what to do, so I can't waste any time making a decision.

I bought stoptech slotted rotors all around. I can't return them now, it's too late. Is there another easy option for rotors that I can get? I really don't like the BMW performance rear rotors, it would bother me to have dimpled rears but not fronts and to have one wheel with slots angling the wrong way.

I could swap 135i hubs, but that's a lot of labor. I could use e91 rear discs (I think), but that's a lot smaller diameter. What's it take to use F10 discs? E46? I'm open to anything at this point.

Thanks,
Tony

On my 08 335d E90 I used the 324x22 E82 123D Performance rotor.

OEM BMW M Performance part number is 34 21 6 795 754 for drilled rotor
Zimmerman part number is 150.2934.20

OEM BMW M Performance part number is 34 21 6 855 003 for the standard rotor not drilled
