I'm so glad this thread is still alive 3 years after I sold my 240. I just recently bought another 97. I wont get as aggressive with this one probably...
Here's my old 97
Enkei RPF01
235/45/17 (I think) 17x8.5 +35mm Front
275/35/17 (I think) 17x10 +18mm Rear
I can't believe I don't have any real good pics of just the wheels on the car..
I did have to stretch the fenders some though
Here's how much they stuck out on the sides
Finally, here's sort of a crap front 3/4ths shot
