s23ho, for that setup, if you are using stock tires, you *should* be fine. You should look at the 2009 GE wheel picture thread, someone is running the rota slipstreams of the same setup on 205 tires lowered with tein springs. I asked him whether he is rubbing or not. check the thread for his reply.

 

Wheel Size: 17"
Offset: +45mm
Tire Size: 205/40/R17 (Toyo Proxes)
Suspension: 1.4" Front Drop, 1.2" Rear Drop
When I Rub: Never, not even with 4 people and luggage. =)

I will confess that I added a Rear Spacer @ 1/4" and I had to slightly roll the rear fenders. Still never rub after the roll.

 

I'm thinking of buying some konig controls in that size and was wondering if I'd run into rubbing issues.
