Winter mods

I have rear upper and lower control arms to install. I'm thinking about installing sub frame connectors and relocating the battery to the trunk and maybe a drive shaft loop since there will be welding going on the bottom side.

Do you think that these mods will produce any noticeable differences?

Are they worth the effort?
 
kinda wondering about some of those things myself, i just got my eibachs but im starting to think ill wait till spring to put em on.. my only "winter mod" so far is the two 60lb sand bags ive got in the back.. i can definately tell a difference with those just on water, but who knows about the snow.. still pretty nervous :shrug:

edit: snow tires to come- any recommendations for 225/55/16s? and would getting just rear tires help any?
