Getting ready to order OME 3" kit

I have a 02 dbl cab 4x4, I am getting ready to order the OME 3" kit from Toytec. My question is on the front coils. I have a factory bumper, but am going to put on a bull bar from Westin. Should I go with the 881 coils or the 883 coils (additional 100lb front weight) ?? I realize the bull bar wont weigh 100lbs but didnt know if it would be better with the stiffer coil over time. ANy help would be appreciated

 

Also whats the difference in n85 (normal valving) and n94 soft valving

 

nothin?

 

im going to run 883's on my double cab iirc someone put these up front and got 2.5+ inches of lift. if your going to put a bumper on up front you may want to go 882 but idk its kind of on the borderline
