Ive got an 89 RS. It originally came with a 305 and the standard RS suspension. The previous owner put in a 350 and a partial IROC suspension. I dont know what parts though. But i was looking to get some new springs because the current ones are apperantly original from the way they feel. Too much cushin for the pushin if ya know what i mean... I want new springs that are performance for the buck and DO NOT lower the ride height... Whats a good set?
