start looking for +2+1 a arms, the stock arms will be put under alot of pressure from the yfz I broke a ball joint on the lower arm on mine, the se are hi/lo compression adjustable with stock arms go all the way out on both adjustments the lo speed is the large nut and the hi speed is the screw.. i think there is a sticky on yfzcentral for those, after you get some aftermarket arms you will really be able to play with the adjustments i like a stiffer lo speed and softer hi speed on mine.
and those are se shocks for sure the way to tell the difference is the step on the bottom of the ressy on normal yfz they are smooth all the way down on se's they have that step on them.
