forgive me I'm in the process of re-reading the whole 50+pages of this thread

....
The M30 hub is almost a perfect swap for our cars. It designed for a front face mounted floating disc. It's outside face without a disc mounted sits exactly where the outside face of the stock MA6x hub sits. The studs must be changed out to 12x1.5mm as the stock studs are Nissan 12x1.25mm. The only drawback is the wheel center bore is typical Nissan 66.1mm, but that can be turned to 60.1mm on a lathe to match the Toyota center bore. Not really a big deal.
and from Wikipedia

The M30's production run lasted for only 3 years, ending in 1992. It is not known exactly how many models were produced, but it has been said that just over 12,000 were made, half coupes, half convertibles, making the M30 the rarest Infiniti ever put into production. Previously rumored by M30 enthusiasts was that only 5,000 were made in total, half being coupes and half convertibles. Speculation regarding the exact production numbers for the M30 are, however, still uncertain
I'm having trouble locating this hub from our normal parts supplier and wonder what the difference between using the MA6x (mkII supra) hub and the M30 (Infiniti M30 (chassis code F31)) hub is. (I did notice that both the M30 and supra wheel bearing part numbers are the same; Timkin Inner set 6, and Timkin outer set 2 or Beck/Arnley Inner part# BEC 051-3842 outer part# BEC 051-3848)

I guess since I cant see a picture of the M30 (post 174 page 18? pic missing)hub its hard for me to visualize what the differences are and how it makes the M30 hub ideal. Is it just where the machining needs to be done? I know that the supra hub was made to have the rotor bolted to the back of the hub and, if I've read correctly, the M30 has it's rotor mounted over the face of the hub. Is this correct? Is it that the outside of the hub face (where the lug studs go through) on the supras hub needs to be machined down where as the M30 is the "snout" that sticks out from the face of the hub in the M30 that needs to be machined instead?

FRONT BBK IS NOW COMPLETE

There is minimum maching required to the hub and no brackets need to be fabricated to mount the caliper to the strut. A great improvement over the stock MA6x brakes, parts are readily availavle anywhere and the maching can be done quickly at a really low price.

If ideal front wheel size is 17x8 +10 offset, this setup will require 17x8 +20 offset. There should be a lot of wheels available in 4x114.3 in this spec.

Parts required as on pics below are.

MA6x hub. Outer edge machined down to ~143mm.

MPV disc. '93 4WD. Redrilled to 4x114.3.
Z32 Caliper/pads. 26 or 30mm caliper.
I know in both cases the lug studs will need to be replaced, if using the supra hub, longer wheel lug studs need to be used (how much longer? I know there was a doorman part number somewhere in this thread or was it a application maybe a landcruzer or landrover or something like that?) and if using the M30 different thread pitch (I assume the same wheel lug stud from above will work?)

anyone have a picture of the M30 hub?


Front:

Option 1
MPV rotor / Q45 caliper (early)
Rotors: 1993 Mazda MPV 4WD Re-drilled to 4x114.3
Studs: It is necessary to press in the longer Dorman studs.
Calipers: 1992-1996 Infinity Q45 Caliper
Pads: 1992-1996 Infinity Q45
Hub: : MKII supra (machined out edge of the hub to 143mm) or M30 hub, wheel center bore turned down from 66.1mm -> 60.1mm (lathe or ?)
Lines: 240SX (years?) one-piece lines
Notes: You have to machine the out edge of the hub to 143mm, need 8mm? longer wheel studs, hub rings, offset change from rotor hat
+8mm or +10mm?

Option 2
MPV rotor / 300zx caliper
Rotors: 1993 Mazda MPV 4WD Re-drilled to 4x114.3
Calipers: 1990 Nissan 300zx/Z32 Non-Turbo 26mm Or 30mm Aluminum Caliper
Pads: 1990 Nissan 300zx/Z32 Non-Turbo
Hub: : MKII supra (machined out edge of the hub to 143mm) or M30 hub, wheel center bore turned down from 66.1mm -> 60.1mm (lathe or ?)
Lines: 240sx (years?) (bolts into MA6x hardlines but you need to remove the retainer)
Notes: You have to machine the out edge of the hub to 143mm, Need 8mm Longer wheel studs, As well as a hubcentric ring

Option 3
RR /Q45 (late)
Rotors: 96-02 Range Rover (8cyl? engine size?), re-drilled to 4x114.3
Rotors: 1998 Range Rover HSE Front Disks (Re-drilled to 4x114.3)
Studs: It is necessary to press in the longer Dorman studs
Calipers: 97-02 Infinity Q45 Front Calipers, Nissan Titan.
Pads: 1999 Infinity Q45 Front Pads
Hub: : MKII supra (some machining required??) or M30 hub, wheel center bore turned down from 66.1mm -> 60.1mm (lathe or ?)
Lines: 240SX one-piece lines.
Notes: No hub machining needed? Offset change?
Notes: Caliper Mounts on shock tower need to be drilled out and tapped, or have inserts or “tap-serts” (in caliper? caliper bolts correct?)

Option 4:
Rotors: 2005-2007 Nissan 350Z Rotor Re-drilled to 4x114.3
Studs:
Calipers: 2005-2007 Nissan 350Z Brembo Caliper
Pads: 2005-2007 Nissan 350Z Pads
Hub: : MKII supra (some machining required??) or M30 hub, wheel center bore turned down from 66.1mm -> 60.1mm (lathe or ?)
Lines:
Notes:10 mm caliper spacer/adaptor ?

Option 5:
Rotors: Anything 300mm Diameter/30mm Thick (May need to be re-drilled to 4x114.3)
Calipers: 1996 Mercedes Benz SL600 V-12 4-Pot
Pads: 1996 Mercedes Benz SL600
Lines: ?
Notes:

Gonna revive some people from the dead on this one hopefully because im running into a few issues and have yet to figure out what im doing wrong Ill for sure post pictures this weekend...

The problem im running into is:
q45 calipers mpv 4x4 rotors mk2 hubs

once I drilled out the rotors and machined down the mk2 outside of the hubs and put in new studs once I reinstall the combination the caliper ends up with about a 1 inch gap between the mounting holes once I line everything up id like to see some detailed photos but my post count is apparently limiting me from doing so?
my original user name was 85mk2supi or something like that I cant seem to log into that account anymore either.lol

Your using the wrong hub.

"Hub:1990 to 1992 Infiniti M30 uses a floating disc and is 4x114.3. Must change studs to 12x1.5mm and center bore is 66.1mm, machine down to 60.1mm. Hub reg is 68mm. Will clear MPV disc."

...the Q45/MPV setup has been shown to work on plenty of MK2 hubs - simply need to grind down the OD of the hub to fit inside the rotor hat and redrill the rotor to 4x114.3

Post your images to IMGUR.com and bring the link here...

Hey guys. I'm going to junkyard today cause they have a 350z vert there. So it's true the calipers will bolt right up? $18 ea for them.

Thanks

I think that was discussed on this board at some point, might be able to find it in a search.

Just finding any ebrake shoes these days is tough. I found some on ebay and ordered a bunch recently. Rock Auto etc doesn't have any more.

Yes, but where to find the elusive 1990-1992 M30 hub...
