I think 9" wide alloys are also an issue - especially on the fronts. A spacer will be required to clear the inner arch/suspension strut. The inner wall of the alloy will be 20mm further in than stock without a spacer. With a 10mm spacer you'll clear the inner edge, but the outer edge will then be 30mm ish further out than stock, so you will rub even if you are on stock ride height...unless you have an extreme stretch on the tyres, say a 215 section width, but then that would be an extreme stretch on 9" alloys.
Most people go with a maximum of 8.5" wheels. You can go for a 19 x 8.5 with an ET45 offset and still lower the car.
Camber adjusters and arch rolling can get you well over 9" if you are committed to the cause.
