need info on r50 lowering kit

[highrollerzaudio]

hey got a question right now my truck has 32" from ground to fender flare lip front an back. i'm running a 22x8.5 +18 offset wheel an a 265/40/22 hankook tire . i know of a couple quys on the forums have a lowered path on 22" but aint sure what size tire there running i assume a 35 series. im wondering if i can run the drop but i dont wanna throw the money in it just to rub or not get the drop cause of factory spring sagging or replacement lowering springs not lowering it.. thanks for any info
