I haven't decided between doing steel rear springs or composite, but I have decided that I will use Eaton if I do steel. Do we know who actually makes the "Grab a Track" springs, or if they use one or more vendors?
I sent an email to Eaton a few months back asking about custom 2" lowering springs that wouldn't be too high in spring rate (I believe in stiff shocks, less stiff springs). I received a reply the very next day from Mickey at Eaton. He said they could build a set of standard rate springs with the 2" drop for $254 for the pair plus shipping.
