Building 1999 maxima for Chumpcar series. I have the q45 rotor/caliper fronts, but q45 rears will not work. We want to go with a larger rear rotor that has some venting, (road courses, 7+hrs). What conversions have worked that are direct bolt in? We have limited brake modification rules and fabed caliper brakets are extra laps down.

 

Custom made bracket with larger disks maybe?

 

virtually no one upgrades the rear brakes. blehmco offered an upgrade for a while, but blehmco doesn't exist anymore, and it was expensive, like $700. it upgraded to a vented disk, different caliper, and a drum style ebrake (it was 300zx parts i believe, I don't recall if a bracket was needed).

best bet is to just get a bracket made and find a disk that meets your size requirements.

or just get the best pads you can for the rear and run some ducting to them to cool them on the dinky solid rotors.

 

Just run a higher temp race pad like Hawks in the rears and you'll be fine.
Most of your stopping power is in the front, that's where your upgrade should be.

 

Ok, looks no one has done this. FYI: the maxima rear caliper only adjusts pad out when the car is in reverse. On the track going forward after 3-4 hrs pad will be worn down and will not adjust to compensate. That is part of the reason I want to use Q45 rears, they are self adjusting.

 

Physics 101: a car slides down hill with
a. Front wheels locked up, or
b. Rear wheels locked up.

Which case makes the car uncontrollable?

Correct answer is b.
