Newbie. 2 or 4 spacers

Followed mostly waveys build

Didnt know where to post and figured me posting here would be better than suspension section. After having my Tacoma for 8 months I finally decided I need to start this build. Hours of research on Tacomaworld I got the parts ordered last week. Have had CBI HC rear bumper, T3 front bumper, and mobtown offroad sliders sitting in my garage for couple months
Archive garage hangers poly bushings
Deaver expo U402 springs
U bolt flip kit
Archive shock relocation towers
Wilco off-road bed spare tire carrier
I ordered my King coilovers and 2.5 12" long travel shocks for rear

After a lot of debate I've decided to chop away and run 35's as you can tell buy once, cry once kinda scheme here. I've ordered spider trax spacers but wasn't sure if I needed 4 or 2 spacers? Planning for method racewheels 305 NV bronze (recommendations?) and Cooper stt pro 315/70/17 used to older generation Toyotas and I've lifted second gens with spacers in years past so some things I'm not familiar with .

Thanks in advance.

 

Most get 4 for an even look.
