Mx5 hubs

[JpHenebery]

Hi Im trying to decide on which donor to use the sierra or mx5, Just wondering if you could clear a few things up for me

Can you use mx5 front and rear hubs without having to have mushroom adaptors or any other bits made up for it? If so do the hubs still need reaming out or do you just use the mx5 ball joints?

Does the mx5 box fit the transmission tunnel built to book spec?

And just a quick general question is the roadster bigger then the locost ie for nosecones and hoods ect

Im sure all this has been answered on here before i just cant find it

Thanks For your help

Google saturn sportscars or ntsengineering and have a look at there build guide for the mx5 roadster tells you all in there

Thanks i will look threw the manual to find out if the mx5 hubs need modifying or not.

What about size is the roadster bigger then the locost?

Yes 2" or 50mm wider.

The Haynes is a very slightly larger car whilst still being very much a 7 and still looking all in proportion. It is a stronger version of the original Ron Champion design and benefits from independant rear suspension instead of the Cortina/ Capri solid axle in the earlier car.
The Haynes book allows for 2 variations in transmission tunnel size to suit either the Type 9 or the wider MT75 Ford gearboxes. If you are going for an MX 5 engine and gearbox use the chassis option for the MT75 width as this will give enough clearance for the MX5 Mazda gearbox. If you want to use an MX5 as your main build donor, this is fully supported too and you should start by downloading the MX5 adapted plans from either the Saturn/ NTS site and/ or the Vodou site. When used alongside the Chris Gibbs book these will provide a set of plans for building a Haynes Roadster using an MX5 donor.
Talk to HandyAndy or Talon if you need a flat pack or welded chassis to suit.
