what camber and toe have you got it set to?
getting the best handling setup does not equal as low as you can get it.
spring rates, ride height, damping, tyre pressures, camber, castor, rake, corner weights etc. etc. all combine to produce a car that handles well.
If you are after looks fair enough it looks like you have a nice car. If you want something that handles as well as it can then you will have to sacrifice the looks. If you go to low with out increasing the spring rates you will risk the suspension bottoming out causing unpredictable handling and rubbing which also upsets the car when cornering.
Take it to a professionel outfit to get it all setup properly and give you some advice. I am sure you are only after the looks really??
