Thanks. All the links should be good now. Hopefully I'll get my new setup up and running soon.
and from Wikipedia....
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.
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)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 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? * DORMAN 610414 ? *) and if using the M30 different thread pitch (I assume the same wheel lug stud from above will work?)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.
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
Yes, but where to find the elusive 1990-1992 M30 hub...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."
