Will add more later.

Guys working on a front brake conversion for the MK2 that will be more affordable. Almost there. Will fit 15" and bigger wheels. There may be some limitations though.

Here is a sneak peek at it. The cardboard is temporary and is there for a reason, I'll explain later.



I should have everything worked out by the new year. Just waiting for parts, holidays to start and exams to finish.

Once completed I will post the conversion on the web so anyone can do it themselves.

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."

I've given up on finding the m30 hub...

I seem to recall someone having found a suitable off the shelf pipe to make spacers that functions same as the wheel hub centering rings. i.e. centering the brake rotor on the stock hub

Anyone remember?
