The rears get some serious camber on them when you lower them. I have pedders on mine, not flash but it sits nicely and won't break the bank. They are as low as I will take mine.
They do have a habit of really squatting down when performing a spirited launch so get some good quality shocks. I have some Evo X rear coilovers which I am going to modify to suit mine.
I think leon r has put some later Evo ones in his RVR, he might be good for some tried and tested suspension advice.
