Ok so I bought and installed;
FRONT
2004 330i zhp front calipers with Cool carbon pads and stop tech ss brake lines ATE/PREMIUMONE CW25138 Front Brake Rotor/Disc!
Install was easy and I am waiting on finishing the rears..........
NOW heres my problem......
REAR
2004 330i zhp rear calipers with cool carbon pads and stop tech stainless lines ATE/PREMIUMONE CW22209 Rear brake rotors!!!
My emergency/Parking brake does not even come close to touching the rotor......
The rotor is way to big for shoes.
Took measurements and the O.D. for the parking brake shoes at driving postion is around 155mm-157
when actuated have a firm very firm feel with the handle and used it to loosen the wheels and rotors on the old or stock rotors.
These ATE rotors are the only ATE rotors for a 330i ci xi etc......they are the 320mm, but don't work with the parking brake....
All my research has led me to believe the 320mm upgrade to the rear is only good if you don't need a parking brake.
Or you could upgrade to the 330i parking brake.
I am assuming that all the 320mm rotors would be to big for the parking brake.
I.D. for the stock rotor is 160mm
I.D. for ATE rotor is 185mm. (I am assuming for all 320mm rear rotors)

Yes I did try and adjust the shoe/brake adjuster at the rotor (not the handle)....I don't think you can adjust it out 20mm at least I couldn't.
I looked for similar series with the same parking brake shoes and all I found were the 328's. Which makes me believe they are the same parking brake setup.
Now I am stumped sort of...Do I keep looking for rotors at 320mm have you ever heard of this.
Should I just go for the 328 rotors (294mm)
I have been looking for the zhp specs and they all seem to be at 320mm for the rear.
Think I'll order the 294 rotors and see if they work with the ZHP. Only reason I want to do this is because I tried to fit the calipers on the ATE rotors and they went on but they were snug, yes rubbing on the rotor, Squeezed all the way in.....
Oh make sure to realease your parking brake when removing the old rotors. They want to stay on if you don't...LOL
I want to thank everyone who has participated in this plight......BIG BRAKES (little cost,
lotta blood)
