Suspension Balance for Street Cruising..THEORY..?

I am trying to build a well balanced fc that is not too boring and not too annoying to drive on the street(with a tight budget). By annoying i mean:my last rx was a vert with large 5zigen fno1r wheels, coilovers, camber plates. That might be heaven for some but not for me. I want a nice suspension that allows me to take corners at higher speeds than oem allows but not be so uncomfortable that the ride becomes jarring after a short period of time. I dont want to be dropped to the ground but a modest drop would be appreciated.
so i started looking into the rb front suspension lowering kit. I like the idea of this because i will not lose any suspension travel up front. I prefer stock or close to stock becuase things stay better balanced and it makes sense to me to use the knowledge that mazda gained through hours of testing and millions of dollars spent. After researching this option, I heard some people say a set of camber plates will also give you a modest drop but you would be limited in angle with the stock springs which is okay with me actually since I would prefer little to no angle adjustment. The idea is just to make the car more capable without completely reengineering the suspension.
My question is: Can i buy a set of camber plates front and rear for my car and effectively lower the car 1/2" to 3/4" while maintaining full suspension travel?
A decent set of dampers would then be in order along with the rb sway bars and maybe some triangulated strut bracing. Trying to eliminate as much body roll as possible and keeping the car from becoming super duper stiff and from scraping the pavement...What are your thoughts?

you dont need camber plates if your not planing to drop since you wont need the adjustment.

just get some kyb agx shocks and racing beat springs.. thats probably your best option

^ It sounds to me like you are looking for an adjustable shock. The KYB ^ said or Eibach Illuminas.

Also look at the Eibach dual rate springs.

I have the eibach progressive rate springs and tokico illuminas, and the ride is still pretty good, and much more controlled than it used to be. I think they are supposed to drop the car about an inch or so, but I couldnt really tell since the stock springs on my vert were already sagging anyway, so there really wasnt much difference.

I've had various setups: RB springs/KYB shocks, Eibach/KYB, Cusco coilovers, RE Amemiya coilovers.

I suggest the RB springs + KYB shocks on stock-sized wheels (i.e. not super-lo-profile tires). The RB springs drop the car an inch or so but retain ride quality. With the KYB's set on 1, the ride is controlled and very smooth. If you want more damping, dial up the shock.

I found the Eibach springs to be painfully stiff - even with the shocks set to 1, the ride was painful.

Mazdatrix has a chart of spring rates here: http://www.mazdatrix.com/h4586-92.htm. Note that the RB springs are much stiffer in front (for steering feel) but very close to stock in rear (for comfort).

I currently have Eibach springs in front on KYB's and RE coilovers in back. It is a good setup but I liked the RB springs all around better. Nice even drop too.

Cheers
