king springs are good.i like em. and paying $755.72 for the genuine lowering kit is pretty hefty.
with genuine sti parts, your always gona be paying more for the sti logo. but then again if you plan on selling the car in the future with the mods left on. genuine sti mods sounds better to the buyer. (if that makes sence)
when i bought my car it already had a whitline rear sway bar. and personally think there a good product.
if i had the money to throw at my car i'de go genuine parts, just coz it sounds better.
oh and not to mention you get a big warrenty on the genuine parts.
