I would steer clear of the wheels if they are 7.5*17 they are too wide for the car.
It is my opinion that your better off getting an offset closer to 40. 35 IMO is just too different to the original ET48.5. I have ET42 which i think is perfect, but then I would!!
FYI when I spoke to speedline about my wheels the 172 Cup that they tested the 17" wheels in ET35 and lowered 30mm on eibachs spring, they experience some rubbing at the front. Nothing drastic they said but it rubbed nonetheless!!
