Sorry kind of a newb with the whole performance thing, just a quick question. I'm looking at getting either TRD or Eibach Pro (i know they are the same) lowering springs, do the shocks/struts have to be changed also to get "stock" performace out of the springs at a lower height? Any camber adjustments/parts needed? Any abnormal tire wear with new springs but rest stock? Thanks

your shocks will just wear out faster. when you lower the car it puts more stress on the shocks. you might as well replace everything at the same time to save yourself from having to do more work in the long run (IMO).

you need to have an alighnment (about $60) after you put in lowering springs but the stock camber adjustment bolt should be fine, no need to buy new ones.

so true, just got mine on (Tein and KYB) and the camber is slightly off but within tollerance.. they wanted $116 for a camber bolt...

Yeah, aftermarket shocks will help add to the feel of the ride too, you can also just get shorter shocks from another car, my friend used shocks for a Cabrio on his Nissan mini truck. As far as camber goes if you increase your wheel size the most that'll happen will be the teeniest amount of sexy negative camber.
