Welcome David,
If you have a well designed chassis that either has, or could be tested to satisfy beaming / torsional testing ...........then I would be tempted to give it a go.
I can not see a lot of detail from your pics, but provided the chassis is well designed, structurally sound and "well crafted"......With a little patience and a GOOD engineer / certifier, I am sure you could work thru' all the other compliance issues.
Front and rear suspension appears to be largely OEM components.......which has to be a good start....a lot better than some of the stuff that I have seen, that has made it onto the road over here.
If you really "Luv" that car and she's a keeper..........then give it a go - You may just get it on the road......Worst possible scenario is a nice track car.
Would be interested to see any data you may have re chassis design / structure. Muz
