Civic and Miata are the right (225) wheelbase but don't fit.
Like on a lot of other things the body hits the servo mounts on an M03.
You can put the body on but it has to sit real high at the front and it looks crap...
The only 225mm alternative that I know of is the Audi TT from Proline. Only problem being that its been out of production for about 3 years...
The HPI Mini and/or VW Concept are both 210mm, they wont fit.
Solution? Pull out the spacer and run 210mm!
