I'm looking into buying the whole TRD lowering package and rear sway bar. TRD offers the rear sway for $165 and the struts for i think $540. The springs I think are $160. Whatever, I'm looking for a reatiler that offers these at the cheapest price. Then I don't know if I should go to my toyota dealership for install or my local speed shop garage?? I probably could install myself but I'm not. Anyone go through this and what route did you take for purchase and install.
