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.

      I found the same with Subaru’s.  I own and love the SG9 Forester, after that model 2008+, Subaru threw the ugly stick at all their line up and somehow managed to make them look worse with every succeeding year.  lol

      It's something we all have to consider as time marches on. Also consider lifted rally MX5 conversion at that point.

      I should be fine for a few more years, whilst I do have arthritis I also exercise and do mobility training every day to keep as fit and healthy as I can, military life, which is the actual cause of most of my joint issues, has set daily regimes, which I weirdly enjoy I also train alot smarter now, not really focusing on lots strength or puffy muscles, I'm more focused on maintaining what I have for my future older self, I actually train as much mobility now as I do exercising Check out this "simple" drill I have been doing daily prior to training now for a while now, this has worked wonders in my all round mobility

      I'd say one thing that may make you sell is the same reason the guy with the hard top roof sold his. He got old, and his back was giving him too much grief stopping him getting in and out... Old guy said he was 73! He looked and sounded younger than 73 to me! Or maybe I'm just aligning with old people more...

      Already looked at a few prior to getting the MX5, really nice car, had all the mod cons, but I wasn't really sold on the new "look" I did miss my 2017 Limited, and I personally prefer the "look" of the older car over the new model, but, when pondering I kept going back looking at MX5's But it was same same for the new ND's, I wasn't sold on the new "look", especially the RF with its weird roof, which only half goes down, like a targa top sort of thing As I stated before, I did look at NC's, but the cars I looked at were PRHT's, but I didn't like their roof line "look" of the PRHT, until I saw the soft top version, (someone on SAU posted a for sale ad for one with a soft top that caught my attention, you can blame them for my choice.....🤣) and.... that old style detachable hard tops were available for them, which keeps the old MX5 more smoother flowing roof line, and the more rounded body style, similar to the NA-NB, to me, the arse end of the ND looks to "modern" Much like how I prefer the NC1 front bar, over the later models How long will I keep this car for is unknown, but currently, there's nothing else out there that "floats my boat" for a small, fun, little "sports car", that I can play with and enjoy looking at and driving But, who knows what the future holds, and going off current new car styling, if I replace it, it will be a older model something something
