DIY E46 320 to 330 Rear Disk Brake Conversion Process

OK thank you Paris

Wow. Great stuff paraclas. I have just gotten hold of 330 front and rear brakes for my 320 (Ihave the same care as u),and have been reading this thread. Was told the brakes was bolt-on, but not the handbrake apparently. I do not have the access and possibility to make that part like u did paraclas, and i was wondering which I part I need to buy, to get this to work?

Regards, Jan

Just to give an update, after 2 years of use my handbrake still works perfectly with this mod. Comparing the 2 reports from the vehicle inspection, one was done 01/02/2011 and the other one 29/01/2013, I was happy to see that the handbrake power values remained more or less the same.

The rear rotors have minimal to no-wear at all, whereas the previous smaller set did have 1.3mm wear within the same time frame. I kept the same brand of pads throughout the conversion (Axxis ULT), which appear to be very harsh on rotors.

There's no ready-made part that you can buy unfortunately. Fabrication is needed, you can buy a set of 330 brake shoes, take out your used ones, or buy a used pair so that you can still drive, take them to a fabricator and have him mate them as my DIY.
