Stance has support in the USA... so that is a big pro if you ever have issues or they ever need to be rebuilt. However, you might want to look at what you want these for: street use, street/autox/light track, or strictly track use. If you are just wanting something to lower the car a little and give you a little better handling, I would upgrade to the Eibach springs with tokico illumina's(see pictures in my build thread to see how the car sits with these, that car currently has this combo) and save several hundred's of dollars. HR springs and Koni yellows are popular as well. Also, you want a slightly less still spring rate in the rear, which the stance coilovers don't have. If you want a good set of coilovers for street/autoX/light track use, the Tein Flex/HA(same thing) are highly reccommended by Howard Coleman. If you are looking for a strictly track coilover, you might want to go a little stiffer than 10k/8k. I just upgraded to R Compound tires and big brakes and am being told by some of the seasoned FD track freaks that my Tein Flex/HA's will not be enough coilover to support the tires and brakes. I'll let you know in October how that turns out.

Also, as mentioned above, check out Howard Coleman's thread about suspension.
