I am getting good reviews on both but bilstein are a bit more.....is it worth it? and got ssc lowering springs to go with which ever....can get agx for about 150 a strut and bilstein comfort for 170 a strut or hd for 230 and that is all new i have a guy with a set of 4 off of a gxp so i think they are comfort for 400 but they have 40k and you should replace every 60k its a toss up alot of money at stake
