No. If you machine the discs then you have to fit oversized shoes. The project Mu rear shoes only come in one size. You could get a machinist to take a pooftenth off, but it's not worth it unless you discs are stuffed. Just use some emery on the inside of the disc as they will be glazed, then bed the pads in. I pull my rear rotors off before every drift meet and do this and they lock up perfectly every time. Project Mu shoes ftw.

The R33 rear brakes have a drum type hand brake built into the inside of the disc.

If your fitting new brake pads get the discs machined as you normally would. If your fitting hand brake shoes, you might struggle to find somewhere that will be able to machine the inside drum, you might have to go to an engineering shop (if your in Sydney I can tell you where to go).

If your fitting the project Mu shoes, chances are its because you want to use the hand brake for drift. If this is the case, i suggest you get them machined as they are usually very glazed and still won't really lock up otherwise. I've machined the drums before on a lathe and without changing the shoes and noticed an improvement in the handbrake locking up (though it didnt last long as the stock shoes glazed them up again quite quickly).

Quoted for truth...

If you've spent the $300 odd bucks on a set of shoes, the least you can do is machine the drums, and that will make a HUGE difference on it's own.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
