Thought i would mention, about 20 years ago i did the same on a 1973 Alfa Spider,in Ca,
was younger then, thought it would make it handle alot better etc,etc, well the mistake
i made was that it ended up the worst thing i ever did, my wife complained,and i was never happy with it,
THe sports springs coil all round made the car so stiff,and very uncomfortable, so removed the springs,
fitted the originals back on, and fitted a set of adjustable koni shocks on instead,made the car great.
But with a pagoda ,im sure would be similiar, but i would not fit konis on it,i like it just stock, the way it is,
But every man does his on thing,hope it turns out the way you want it. regards.
