I have yet to see anyone convert an R5 over for full street (legal) use, and that would be insanely cool, and is one of my 'lottery winning' car ideals/projects.
One of the only ways one could have an AWD Fiesta with a STRONG, well thought out/engineered drivetrain and fully independent suspension, albeit with the disadvantages of a Sadev sequential gearbox
on the street (unless you engineer/fabricate something to allow the use of the H pattern IB6 with it?
).
Can you run as street legal with the full FIA certified cage, and without any of the air bags, in Holland?
