It sounds hardcore,but probably wont really be

Its suprising how big the rear wheel arches are in a mk 1 corty...just a bit of sheet metal work,you couldnt really call it tubbed...technically[:p] Im hoping to borrow a friends 285/35/18's off his stanza to use as a guide.If they fit,then everything I want to throw under the back should fit with no worries

You can fit 255's as a tight squeeze width wise as standard but you wouldn't want to drive on them[%] Im hoping to get it in to the panel shop the weekend after easter.
