If you end up having to deal with chassis tech, BEWARE!!! They are horrible on the phone, their parts don't fit, some of their stuff is good, and other is complete crap. Not telling you don't, just be very very very careful with them.
Well that is what I have been leery about because they are rude on the phone, shipping prices suck, and they charge you to powdercoat parts that should already be powdercoated...
You will never get your alignment right with lowering springs. I told this to a guy on PSN. He bought the springs anyway, and then after a little while of messing with it ended up getting the dream beams. Save yourself some headache later and do it right the first time.
