Coilovers are only as good as the struts you use... if you have junk struts and put coilovers on them they'll be harsh or just as clapped out as they were prior to the coilovers.
If I were just building a car to cruise on the street in nice weather I would keep it as simple as possible. I would field the options of tubular
control arms with spring perches vs replacement factory arms with bushings/ball joints already installed. See which one makes more sense cost wise. It maybe cheaper going the tubular a arm round which then you'll shave a few lbs off the car and look better to anybody that bothers to look under your car lol.
Spring wise just stick with the stock springs or a quality lowering spring. If you lower your car though, remember if you don't spend the money on the strut/shocks your going to suffer in ride quality section no matter what spring or coilover setup you open the purse for. Could you deal with lowering springs on clapped out struts/shocks of course, would your girl appreciate better struts and shocks? of course should would
Not saying you have to go right to top of the line but don't fall into that pit of
trying to save some on the struts\shocks by making the mistake of purchasing marginally better quality ones over factory.
There is no camber bolt with these cars, their are
camber plates on your strut tower that are non adjustable from the factory. You shouldn't need caster
camber plates like I mentioned in a prior post for a stockish
suspension car. They come into play when alter the height and wheel base of the car a good bit or if the car is not striaght or true which happens but should really be corrected the right way.
