GReddy/GRex brake system replacements

Hi All,

Needing new brake pads and possibly even brake discs for my car.

I have a set of GReddy 6 pot Calipers with 355mmx32 brakes on the front, and GRex 4 pot 330mmx26 brakes on the rear on my R34 GT-R. These are NOT the alcon branded brakes, they are the ones seen here:

Fronts: https://www.nengun.com/greddy/6pot-brake-system

Rear: https://www.nengun.com/grex/brake-system

These kits and any replacement GReddy branded replacement discs and pads etc. are no longer in production.

I am wondering anyone else that runs this brake setup has replaced their brake pads with non-GReddy parts and if so, what fits?

Also, if anyone has had to replace their discs what fits, or did you have to get them custom made?

I have searched the interwebs and have found very little information regarding these brakes. Some say they are made by Rotora in the US (at least for USDM GReddy).

Other posts have mentioned that the front disc is a copy of the 355 x 32 Brembo rotor so the Brembo is a straight fit.

Calipers may be a copy of or even made by AP Racing...

So hopefully someone out there has been through replacing these parts and knows 100% what will or won't fit.

Thanks,

Paul

They look like the same as the AP 6 pot/G4/Attkd/D2 whatever pads to me....like GTSboy said trace them and see.  

Discs look harder since they are 10 bolt (m6?) and obviously we can't guess the PCD from a pic. Measure the offset and check them against the DBA catalogue to see if anything else will fit? Very likely you will have to change the hats as well, not just the rings

I suggest talking to Matt at RaceBrakes in Wetherill Park, he will be able to work out what does or does not fit.

      From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
