I think thats something I will have to play with once the engine is in and running etc. I know the poundage of the springs will have to be played with and probably go for coil overs all round. I may end up needed to alter the geometry of the suspension etc but I am not really going to know until its driving and take it from there. The fuel tank and battery will probably be mounted up front aswell. There are conversions for mini's using Vtec engines in the rear and they must have shorter wheel base than a saxo but they do a complete front and rear frame.

Heres my project page for my old pug.
