the only thing that could be affected by the lowering of the car would be the front. As you lower the car, with macpherson struts, the toe will go in and you get more negative camber. The rear will not matter due to the geometry of the rear...or the lack there of. haha
there is a sweet spot for lowering the car. You essentially want the control arms to be parallel with the ground. If you go too low it will have a negative affect on the handling because of the geometry. I found this out when I had coils on my elantra...i raised the car up some to get everything parallel and it was much better...after they blew i went to a spring strut combo and it was even better, because the coils were actually TOO hard. (though in retrospect...it could have been because the tires were loosing traction...if i had some uber sticky tires on there it might have helped quite a bit...but this is another one of those..are you going to track your car questions and the need for coils.
