i have driven with a lot of different set ups on STI`s and WRX`s as well as installed them.

if you want a great ride, that is not to bad on the wallet mod, the BC`s the way to go. great entry level coilover.

i have had 10k (kilogram) as well as 1000lb springs on coilovers on a suby, stiffer springs doesn't mean better handling. you will be skipping across the pavement rather than sticking to it... but if you dont plan to do any racing, i would recommend doing H&R springs on some AGX struts. this will probably give you the best daily driver comfort, with increased handling. and you can install them yourself with minimal tools.

but if you are set on a box set coilover package, the BC is the cheapest, and i have installed 4 or 5 sets and everybody has been happy with them.

i had Teins on my car and i didn't like them. i went with Ohlins on my GTR. IMO, there is not a better set up out of a box that is made to order. but the cost is more, as well as wait times in most cases.

if you have any questions feel free to send me a IM.
