S tech will lower the car much more, and therefore will stress the stock struts more. also have heard that they are a little more bouncy (the crucials dont bounce AT ALL.. hella stiff)
and no i dont work at gst lol
red springs could be cheap-o drop zones, skunk2, or hopefully Swifts. eibachs are black from what ive seen. If they are swifts theyre great springs. it was a toss up between swifts or crucials for me
