i'm working on the *assumption* that the track width is the same with the wilwoods as it is with factory discs. and if so, then you'd be tight, tight with a 225, even on 4.25BS if you're low.
but if you aren't low, and don't have wheel lip molding, and have some decent t-bars... as long as you don't go divebombing driveways at full lock you'd probably be fine. if you went down to 215's i'd venture to guess you'd be okay.
