You have a few options here with regards to mx5 Roadster plans.

Saturn plans I have a copy but a few measurements are missing from the wishbones...
Vodou plans are incomplete at the rear with regards the rear coilovers.....
or
Build a standard roadster chassis as per the book and replace the mx5 ali diff cover with the arms for a fabricated diff cover and make custom rear wishbones.

Hi Andrew

This is my first ever post!!!

I started the Haynes Chris Gibbs this christmas and am using the MX5. I have used the saturn plans and yes some rear wishbone measurements are not there.

I am currently making the jigs so shouldn't be toooooo long before I can trail fit the rear wishbones. I have made the bottom to the book (as the Saturn plans say) and need to work out the tops.

I am going for 90' for the hub then use the adjusters for camber. A good enough starting point I think.

This is my first build but have run stockcars (got too old for these) for a number of years and I am an engineer

Can keep you updated if needed, or if anyone has any measurements that could help?

many thanks
David

We are building a Roadster to the Chris Gibbs book so it will take standard Bodywork.
It will be designing to take the (MX 5) diff, gearbox and Engine.
We will also be designing the Suspension from first principles to take the Mazda wheels, hubs, uprights and brakes
The build is only up to page 37! so far but the drawings are further advanced.

Once the build is proved I am willing to provide copies of the changes we have made.
U2U me and I will start a mailing list.

Rear wishbone measurements missing not a prob. All you need is a braced triangular ish shape to get your wheels in the right place and to allow for a slight amount of adjustment. That's how I did mine - on the road 6 years ago You know how a ruler works so measure them up yourself!
