let me chime in here as i had v3's on my BRZ. at my lowest height i had no gap in the front and was almost tucking tire (i have 265's). i recommend other suspension ad ons if you want to drive the car at that height and have any kind of good handling characteristics.
now, driving this car low isn't that hard, just angle EVERYTHING. with that said, KW isn't really hte slam your car coild over, as posted above get taiwanese stuff for slamming a car.
with all that said, the v3's will get you pretty low, i had maybe another 1/2" to go in the front if i wanted to be cool
here is a picture of how my car sat for a week or two being "low"
the frs you posted looks like its on 17's though. i'm on 18's with a big tire (i dont believe in stretch)
p.s. my kw's are actually for sale if you're looking for a good deal/a mint set. look up my threads if you have more questions, i was running whiteline com-c tophats, with other tophats you will probably be able to go lower...
