+2 Hubs on rear of S4

Any reason not to put +2 hubs on the rear

I know I need to have the fenders flared

Wider track!

No reason as far as I know, not sure you will gain much apart from additional clearance between the wheel and the strut. Do not underestimate the amount of time it will take to flare the arches properly. I started to put on 26R arches on an S4 a long time aqo, the fit of the rears were poor and a lot of time has been spent getting them as I want them. Unfortunately not finished and other events have now stopped progress.
I've got a spare pair of +2 rear hubs if anyone needs for a very reasonable price.

I have plus 2 hubs on the rear of my S4 no problem with the arches and I think they look good
