Just arrived in comments, from Filip in Poland:
Need advice on wheels for 9-3SS V6 XWD, plse. I’ve recently bought one with sports suspension, 18″ wheels and larger brakes. The wheels are basically the same as in Turbo X. The idiots at local Saab dealer (Warsaw, Poland) said any 17″ Saab wheels would be ok as winter wheels. To my (and their) astonishment – standard 17″ wheels were too small for larger front brakes. Does anyone know which 17″ wheels (if any) can be used in this model?
I have a feeling that you’re going to need to get 18s if you’ve got the bigger brakes, but I know little about these things.
So it’s over to the techie people……
Having a look at nearest English-language car configurator to yours, with that model the smallest wheels you can order are the 18s. And with the 345mm performance brake kit, I’d tend to think 18s are the smallest for exactly the reason you’re now facing – your brakes are huge!
Despite your wheel issues, Filip, enjoy the Aero!!!!
