Which lowering springs should I choose?

[computerlove87]

I am looking for a slight drop for a 2009 LB 3dr that maintains ride comfort and more importantly evens out the front and back end of the Yaris (so that the bottom of the car is parrallel with the ground instead of being at an angle from it)(think of what a stock yaris looks like if 2 adults are sitting in back.). I do not like the fact that the yaris looks like the back is higher than the front. most people tell me to get the tannabe nf210's, but I heard there was a set from tein that works even better for an even trim. What do you guys think?

Also, I want the tires to be a little bit farther out from the chassis, and I also saw these:

H&R wheel spacers. I have absolutely no tuning experience, so I have no idea what these do. What do they do to the ride comfort? the handling? are they bad for the car in any way? Will there be too much rubbing with these AND lowering springs?
