maybe. I think the widest wheel you could get by with is 235/40/18. The offset will have to be perfect or you will either rub the strut on the inside or the rear fender arch on the outside.
Without some kind of camber adjustment your expensive tires will suffer from inner tire wear in the front. Either get a camber kit, have new holes drilled, or have the strut towerplates repostitioned.
BTW - my 17" wheels with 235/45/17's and the Eibach kit rubbed a little bit on the rear fender before I took a Dremel and shaved the inner lip down. My wheels have a +35mm offset so they stick out a little more than the 42-45 offset. Looking at the car from the front the fron tires appear to stick out from the fender about 3/4", but the do not rub or bottom out on the fender. I'll post a pic if I can find one.
