I know a couple of people that use them on their S14, they go low and ride fine. But for track days, I wouldn't count on them lasting a long time.
I myself have Fortune Autos, they are one of the best entry level coilovers for the money. If going low is what you want, get the new PBM pros. FA front coilovers don't go low unless you trim down the lower bracket or flip the bracket (it adds positive camber though). Stance/PBM pros (not the gold ones)/FA would be your best bang for your buck.
Add swift springs to any of those and they will be great for DD.
Here are the rears, they can go plenty low.
