is it possible to change width on work varianza??

is it possible to change the width of a Work Varianza F2S

size is 
19x8.5, +45 offset

if so where can i order it and what do i need to look out for..
thanks a lot for the help and sorry about the noob question.

arent the work varianza 2pc welded wheels??dont know if that would be possible.

what about the Work Euroline Type-N wheel?? can i change the width/lip size on that.

the 2 piece weld one you cannot...

and those 3 piece one that can be taken apart. unless you want those discontinued models for full rebuild regardless of budget..other wise not worth it to take it apart. cheaper to get the right specs. the first time.
