takai's IPRA AE86

Nope, sat inside the disc hat, but cleared by 5mmish all the way around.

Hmmmmmm

Couple of little updates:





People should be able to work out what they are.

[fantapants]

nope.... im confused....

[ONCE-NA]

Traction brackets and somekind of calliper bracket/spacer?

[takai]

Traction brackets, and a backing plate for the new caliper bracket.

Took this pic for other reasons, but figured it fits here too.

Got stuck into finishing off the caliper adaptor on Sunday. Ground up a piece of 25mm plate to fit nicely in the little gap:



Its only tacked together for now (and badly so since i couldnt get the head of the MIG into the gap and so i was welding with about 2" of wire hanging out the front.
With it tacked together ill drill and tap some M8 holes to add clamping force and then grind it apart, bolt it back together and MIG it all up.

Rolling along nicely

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 4x114.3, 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 aroudn to fitting the diff gears tonight. Only problem is finding marking paste.

Nice work i like it! i like the idea of how you drilled the rotors, very simple and easy.

what s13 rear rotor do the brackets work with? i went to a shop and asked and there was a few to chose from, sr or ca were the options i think? 240mm or 250mm
