Wheel offsets

[camden_bmx13]

what would a wheel that has the offset of 3:6 give me in adding width to my 400?
(I know about the thread posted on here but it doesnt help.)

isnt stock 3:5?, if so nothing, just one more inch inside

[camden_bmx13]

so what your saying is that it would cause me to lose width?
