I have. 2009 997.2 base cab, with 18 in carrera iv wheels looking to upgrade to 19's. I am looking at a set which is 19x8.5 et 57 and 19x 11 et 67, would these fit? I'm thinking spacers may be needed in the back?

There is another option for the back 19x 9.5 Et 46 would those fit better? Dont know much about wheels or offset...thanks.

Looks like the base carrera ivs are 18x8.5 et57 and 18x10.5 et 60.

 

There are a ton of threads here and Rennlist. Check out both and type offset, narrow, wheel, etc...you'll fined plenty. And good pics to judge for yourself...

 

The set you are looking at is exactly what I currently have, including the offset. Take a look. Hope this helps. The need of spacers are subjective. Some have told me it looks perfectly fine but I think I need spacers. You be the judge.

 

Thanks a lot, looking pretty good. I think maybe some small spacers might help but not mandatory.

 

You can use those offsets on your car and that's OEM fitment. Spacers are only needed if you want a desired look, not because the wheels rub against the suspension...
