Differentials

For the Mazda I am thinking about getting a later model Hilux Rear Axel including Disc brakes. Then shortening the Axles and tubes and fitting a ARB Airlocking Diff Centre.

*UPDATE* 1FEB17

A Limited Slip Differential from an ED Falcon came up on Gumtree for a good price with the advantage of the stud patern being 114.3 X 5 which is the same as the RX-7 so will match the front RX7 Hubs. The axle assembly is far too wide at 1550 but this offers plenty of axle to either cut it down and re-spline or purchase 28 spline 9' axles the right length as many options are available.

    That would be too heavy for the little Mazda to turn!

Shortening the Diff

I have a Ford 8.8 inch diff from a EF/EB Ford Falcon with a Limited Slip Differential. I want to shorten it down to suit the 323. Due to the RX7 LCA in the front, the front tyres(205X50X15) now protrude from the front guards by 65mm. Making the overall front track width 1,675mm. With 225X50X15 tyres on the rear and the standard diff the rear is 1,610mm. Meaning that the rear track width is 32.5mm narrower on each side. To widen the rear when I shorten it, I'll make the rear axle 65mm wider than the standard rear axle. The standard 323 Diff width is 1,338mm and the Ford 8.8 is 1,547mm for a total difference of  209mm. So the Diff needs to be shortened by 209mm - 65 =  144mm or 72mm per side.

Suspension Design Solid works

To assist with integrating the Mazda RX7 S4 FC front suspension into my Mazda 323, I've decided to see if I can create a solid works model for the suspension and then one for the Mazda chassis to see what fabrication work is need to integrate it. Looking online into engineering tutorials I found a site called Grab CAD community and a tutorial on there around spring design in solid works which looks fairly strait forward. https://grabcad.com/tutorials/tutorial-how-to-model-a-suspension-spring-in-solidworks-and-show-design-intent The main issue I have is the Lower Control Arms (LCA's) are a rather complex shape and will require me to up-skill in SolidWorks to be able to reproduce them. I'm in the process of sandblasting the part and taking some better images from which to model it. *UPDATE -- 1FEB17 nearly finished sketching the LCA and spindles
