I wonder if they make a two piece rotor that doesn't require you to change that stock pad for the 135i. Yeah I definitely wouldn't go that route if I were you. Having to buy custom pads or shave your pads down every time you have to change them would suck

They are expensive alright. Not sure I'd want used parts though for those or the halfshafts which makes the total amount pretty much what it's going to cost if I do this. The parts numbers are only those that are different, they don't include the bearings, clips, lock washer, cone nut, etc.

The only reason to do this is to get fixed calipers and floating rotors at less cost than a BBK. Of course rear BBK on these cars is kinda pointless but after bumping the engine up and cutting the weight, that's arguable afaic. Having to go with custom pads pretty much kills the deal, that and the 135i rear floating rotors are close to $900 a pair.

Don't know of any other two piece rotors but have pinged Powerbrake to see if they have something close.
