Has anyone actually done this yet?

I know they don't just boly up but thought someone would have maybe made some brackets or something made up by now

I'm asking as i just bought a GReddy 6/4 brake kit for my car (i was under impression when i bought it they would bolt up :no: )

So before selling them i thought i'd just see if they could actually somehow be fitted to a 32 R

Looks as though these won't fit

Pulled my brakes off today and thought i'd see for myself what needs to be done for these to fit

First of all lets just say once you have dust covers out of the way the disc will fit perfectly albeit the handbrake pad surface area is 5mm narrower than that of the R and as well known in these forums the rotors them selves have a different offset bringing the disc closer to the wheel

The caliper is a different story, as mentioned elsewhere on these forums the bolt size holding caliper in place is bigger than that of the 32 (prob same size as 34 IMO). This isn't the only problem though, the spacing for the bolt holes is 10mm further apart than that of the 32 and finally the final offset of the actual mounting brackets that actually hold the caliper onto the hub is also different resulting in pushing the rotor out off the hub by 5-10mm when in place

So for anyone thinking of putting a set of 350z brakes onto there Skyline the mods that i can see needed to be done would be

* Weld in the holes that are in the hub assembly at moment

* Mill required 5-10mm off the hub assemblies mounting point facing the disc

* Weld in new billet piece to outer side of mounting point to accomodate the amount you took off the opposite face

* Redrill the mounts so there out a further 5mm on each side to accomodate the wider spacing on caliper

This doesn't take into account the engineering side, would this make the mounting points weaker? Would bracing be needed? etc etc

All in all IMO i think it's too much work when you can buy another set of brakes that will bolt straight on

So saying this anyone know someone with a 350Z that wants a set of GReddy 6 pot 358mm fronts and 4 pot 330mm rear brakes? lol

Here's a dummy pick of wheels on with brakes in place but as mentioned the rotor was NOT sitting flush on the hub

No, the conventional way to mount calipers that require a different bolt spacing (and possibly size) and where the calipers need a different offset in or out relative to the stock ones, is to use a dogbone bracket of some sort. Sometimes you just can't make that work, but you usually can. If the caliper ends up moving a long way from the standard location you may also end up needing a sort out some flexible lines as well.

Being that the calipers are so close to fitting there's not room for any style of bracket IMO

After talking to a friend this arvo he has a mate that does CNC work at home so he's going to ask him about this project tonight

If he reckons it's doable i'll buy couple uprights and send over to him and see how we go

Mates friend says he's done heaps of brake stuff for people so i have set of rear hubs on way to him now along with these brakes for him to have look at

Also taking spare front hubs i have hear to him also to drill out the mounting holes for the fronts (better job than me drilling with hand held drill lol)

Will keep yas updated as progress happens so we have a definate thread to answer this question in future

Just for reference purposes

These are the 6 pot 360mm fronts from the kit, also off the 350Z

Only thing needed to be done to fit these to an R32 is either trim or bend the edge of the dust plate back so it doesn't scrape on rotor and drill out the mounting holes in hub to accept the bigger bolts

I was suprised that the caliper didn't even foul on the dust cover whatsoever

      Need AC Compressor for R32

      By Zabuza · Posted

      Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?
