I did a search and didn't find what I was looking for does anyone know can you just pop in a set of lowering springs say from Hotchkis to achieve a nice drop on a C20? I am buying one and want to save up for the whole kit to convert it over but it's like 5500.00 from Hotchkis so for the time being can I just swap springs to achive my desired stance without changing over all the control arms and spindles and axles to C10 gear? Any advice appreciated. Thanks in advance.
