Ok. I know this has been gone over before, but not in exactly my case. What Im looking @ is rota boosts 17x8 with either a 235/40/17 or 245/40/17. Wheels are a 48mm offset. I drive an 05 wrx sedan, it is lowered with s-techs. Do you think that I will have to roll the fenders. Its not that it is that big of a deal, I just would like to know what to expect. Thanks in advance.

 

Definitely will have to have your fenders rolled.

 

Definitely roll the lip, and quite possibly flare them a little too. You may not be able to run 245s without removing your front fender liners, since they are held in place by the lip that you have to roll.
