Well, what I mean is you want a 50mm strut to base your front suspension on.
If you go for coilovers you can get a full kit with springs shocks brakes etc, like BC's, AJPS, plus many others, not to mention the people that do custom coilovers.
A good place to start is by reading through build threads, and see how other people set their cars up. Obviously you need to take it with a grain of salt, but its good for a general knowledge of how to go about things.
Also, does your budget allow for coilovers? For decent new coilovers and brakes it will cost around $1500.
