I'm looking for a BBK recommendation that covers these requirements.

-Fits in the m359 wheels without spacers
-Covers front and rear
-Ebrake is still functional
-Isn't loud or squeals.
-Replacement pads and rotors will be easy to obtain 10-15 years from now.

Any thoughts?
I believe our front CP9660/372mm AP Racing by Essex Radi-CAL Kit would be a good fit for you:



This system clears the ZCP wheels without a spacer (and many others...list below), and was also specifically designed to fit inside 18" wheels if that is of interest to you.

Confirmed wheels that fit without a spacer:

OEM 18" Wheels
OEM 19x9" front Competition ZCP Wheel
OEM 220M 19x8.5"
APEX ARC-8 18x10" +25
APEX EC-7 18x9.5" +22
APEX EC-7 18x10" +25
BBS FI 18x9.5" +22
Enkei NT03+M 18x10 et25
OZ Challenge HLT 18x10" +25
Signature Wheel SV503 18 x 10.5 ET22
Titan 7 TS5, TS7, and TR10 18x9.5 +22
Titan 7 TS5, TS7, and TR10 18x10 +25
Titan 7 TS5, TS7, and TR10 18x10.5 +25
Volk TE37 18x9.5 +22

We also have a more road-oriented kit if you aren't planning to track your car.


I'm not 100% sure if it will clear the ZCP wheels since it is a newer release. It does fit the OEM 220M style wheels without a spacer as you can see in the pic below. You can check front wheel clearance using this template:

If you're unsure which type of AP Racing kit is right for you, Competition vs. Road, you can check out this page:

To address your other concerns about a brake kit:
  • Our Road and Competition Brake Kits both retain full parking brake functionality
  • Both systems have pad shapes that are available in Ferodo DS2500 compound, which is what we consider the ultimate road/sport pad. They are very low noise, but have a very high max operating temp, and would be great for your car if supercharged. We have 1000 HP ZR1 Vettes running around on them.
  • Essex has been in business since 1981. We hold hundreds of sets of spare iron discs and pads on hand at any given time. We are in Charlotte, NC, and have a staff of 24 people. We have no plans to go anywhere anytime soon, and offer the best support in the business. We're also long-time forum sponsors.

While our systems are cheap, they are the best in the business, and they retain their value tremendously well. The AP Racing name is synonymous with quality. They typically trade hands for about 65-70% of their original value on the used market, so they truly are more of an investment than most aftermarket parts.

We have set up hundreds of e9x M3 with brake systems, and you can see many happy clients on our blog:

If you need help deciding on what is right for you, we have a team available to answer your questions standing by. Please let us know if/how we can help, and thanks for your consideration!
