If anyone is building a Haynes Roadster I would be gratuful for a measurement from it if you have got to the fitting stage of the rear suspension. I could do with the measurement of the width, hub to hub if fitted with drum brakes or disc to disc. I have a crazy idea of building the rear suspension arrangement of the Haynes Roadster into a lightweight hatchback (Citroen AX etc) with front engine as a classic trials car. I need the measurement to see how it compares to various hatchbacks.

At a guess the roadster has the same trackwidht as the sierra, 1470mm with ET35 wheels. That would make the the hub-to-hub measurement 1400mm. Or thereabouts....

It's been done before with the MK indy rear suspension setup in the back of a yellow fiat 500 some years ago. I think that was powered by a blade engine but am not sure.

Found it; here it is: http://www.fiat500club.org.uk/clubchat/viewtopic.php?f=1&t=5605 loks very MK-ish in the back but possible a bit narrower.

Std sierra is approx 1540mm drum to drum track will depend on wheel ofsets.

Thanks for that. The 500 looks awsome. I want one!!!!

Track width all models except p100............1468.0mm(57.8 inches)
P100 models...............................................1414.0(55.7 inches)
According to Sierra Haynes manual.
