For the rear, we opted to use DBA’s 4000 series rotor. This is a one piece rotor made necessary by the G35’s use of a drum type parking brake that is integral to the rear rotor. This makes the use of an aluminum hat impractical for a street car. The 4000 slotted model has a unique 6×6 Wiper Slot design for exceptional venting of vaporized brake pad. Unlike many aftermarket rotors, the 4000 series has a coating of heat resistant paint on the center part of the rotor so if you have open wheels you don’t see a nasty rusty looking rotor.

| The Brembo 350Z front caliper has 4 pistons which have dust seals and correct proportioning for the stock G35 master cylinder. An OEM caliper also has anti-rattle hardware unlike racing and high performance calipers. The calipers bolt right on. |
The DBA rotors have stripes of thermal paint on the outer edge of the rotors. By observing which stripe of thermal paint burns off, you can determine what temperature the rotors reach and choose an effective brake pad for the temperature reached on the track. This is a practical and neat detail that to our knowledge no one else does.

| The rear calipers have two pistons. They bolt right on as well. However you must use the rear caliper mounting bolts for the 350Z track package as the mounting ears are thicker on the Brembos. |
We had a minor clearance issue with our Rays AVS wheels and the front Brembo calipers. The caliper just barely contacted the wheels spokes on the lower side of the caliper. To solve this issue we used 12mm H&R hubcentric spacers and some longer Nismo wheel studs from G-Spec Performance. The hubcentric spacers are much truer and more secure than plain standard spacers as they positively fit to the hub and the wheel center bore. The spacers also helped fill out our large wheelwells better and the change in scrub radius didn’t seem to affect our handling.

| Project Mu NS compound brake pads are excellent for street use, the are low dust and quiet. |
In light of our anticipated street biased use, we obtained some street performance brake pads from Project Mu. We selected the NS compound which is designed to be a high performance street brake pad with decent overall performance. The NS compound has a pretty stable coefficient of friction or Mu of 0.4 to 0.37 over its thermal operating range for decent bite.
