After some consideration I think probably the Mazda MPV rotors will be a better option. For one it doesnt mean that i have a monstrosity of a bracket, instead i have something much flatter, as so:

Note that the big chunk of 12mm steel is only there so i can gauge where that flat plate is sitting. Its acting as an impromptu flat plane as i didnt have enough hands to hold the ruler and camera and a flat plane.
Secondly, it allows me to use the other set of Simmons V4s that i have had around the garage for a while, as they are +20s, and with a 15mm bolton spacer it brings them back to ideal offset and therefore scrub radius (stock/ideal is 0ish offset).
As so:

Thirdly i wont be cooking the balljoint as much as i have been previously with the disc so close to the ball joint. 4 ball joints in 3 years is probably too much.
Therefore i needed to redrill the MPV discs to 4×114.3, which could be a pain, but here is a simple way to do it.
Firstly machine down a chunk of metal (2011 in my case) to the outside diameter of the new disc, and then the old disc, in my case 72 and 60mm respectively:

Should look something like that
Then stack the discs ontop with each one being a tight fit with the location ring as so:

Finally, after lining up two of the holes (and using something to dowel them, not pictured here) use a transfer punch of the correct size to mark the disc below:

Then all you have to do is drill at the markings. Truely a piece of piss.
In addition i picked up some brackets yesterday to allow me to run slightly larger discs at the rear, some S13 discs infact:

Going to try and get around to fitting the diff gears tonight. Only problem is finding marking paste.
So tonight and over the weekend i did a bit of work on the MPV conversion.
First however, i did some work for BigPerm on his Cressida stuff:

Machining out tophats, oil seal rings into coilover sleeves, making little alu spacers and soon to machine his hubs down. Lots of fiddly things.
Inspired by that however i swiss cheesed the traction brackets:

So they are ready to weld on and then be trimmed to size.
And then setup the brake upgrade with the MPV discs:

Uses the stock RA28/40 brake caliper adaptor:

Which ill have to weld a 5mm plate to the inside of to drill and tap (along with a 3mm plate on the outside for extra tapping)

Coming together nicely, i would have welded it tonight, but i had shorts and a tshirt on and didnt want to make noise for the neighbours any more than i already had.
