I went to auto max for a quote on a set of iroc heavy duty springs for my 84 camaro. I'm using the 89 iroc as a reference for the set. This year as a choice of 2 spring sets for the front, regular and heavy duty. I asked for hd and he told me I would need the longer iroc struts and longer sway bar links from that year. I have oem struts in front. I already put the non varible in the back combined with kyb gas adj. and after maket poly kit Please seaperate fact from fiction and me advice. thanks.
