My sister had K-Sports in her 09 Foz xt and the quality is really good and the handling was even better but if you're going to spend $2k then there are better brands to get.
Also if you're going to buy some anyway then why not support some of the paid vendors on here that sell coilovers, I'm sure they will do you a good deal.
Ultrex can get buddy club and prospeed can get quite a few good brand-name coilovers.
