And I need an approximation of the backspacing you have now as well. Widths and backspacing of what is on the car currently...so I know which type of uprights we are dealing with.
I looked closely at the pictures I found here :

If you want to race you need a new set of wheels. For the street you may be able to use what you have on the front but the rears appear to be custom made and I do not think they would fit in an attractive fashion under the spyder bodywork. The fronts are drilled already for 6 studs so at a minimum you may need hubs. How do you plan to use the car ? I think the best bet would be 9" front and 12" rear...with an older set of race Dunlops past their prime.
