<VV> bushing upgrade advice wanted

[Ramon Rodriguez III]

I think this might be too complicated a question to answer but I'm going to
ask and see.

This question is directed at the racing guys mostly.  I am upgrading my 66
Corsa coupe with autocross and road course events in mind and want to start
replacing bushings and such.

Can anyone give me some advice on what bushings and such to replace first
(I will have to do the car in stages for financial reasons mostly)?  I'm
hoping for upgraded bushings (Nylon?) where applicable, but no metal
bushings.  I plan to stay in IS-3 class for now at least.  I don't mind a
harsher ride but this car will still be driven plenty on the street.  I
like to someday get my suspension working similar to what I experienced in
Kevin Wilson's car at Sturbridge.

Thanks!
