I know people like to get coilover selves, but I think it is better to get the whole coilovers, like tein, tanabe, etc. The coilover are design to perform the best for your car. If you get shocks and coilover springs, the ride is not as comfortable. Coilovers have camber plant in the front, but you need to buy camber kit for the rear. If you lower it too much without changing the camber the wheels would look like / \, and you will waste your money for the tires.
