I am doing research for a project and wondered if any of you could help me fill in some gaps. What I would like to know is weather the early Subaru/Prodrive 555 Group A cars were equipped with tubular front crossmembers and rear subframes. Also I wondered if the front control arms were STi Alloy peices or also tubular. lastly, were they equiped with upgraded custom hubs or factory peices. any information on this ro any other aspect of these cars would be appricated.
