wheel offset help needed

[spudz5]

Need some help with someone familiar with offsets for a NB 997 C2. I am looking to get a set of wheels and there are a variety of offsets available. I want to know if the following would fit my car. 19x11 offset 50 19x11 offset 40 19x12 offset 63 thanks

These are the best sites I know of for comparing wheel/tire sizes. Stock 11 inch wheel (rear) is a 67mm offset for comparison, with 295/30 rubber. 67 is also the offset for the 11.5 in rim with 305/30 tires.

51 is the offset for 19X11 turbo rear rims. With 305 tires, probably as aggressive as you want to go in the rear. So, the 40's aren't going to work. Can't really tell you about the 12's. Extra 12.7 mm in et from the width with 13 mm farther in from the et, should fit very close to the 11's with a 50 offset. Very aggressive choices for a NB though. Best to see how the actual wheels look on a car.

19x11 et50 will work no rubbing, 295/30/19 or 305/30/19
19x12 et63 will sit out exactly like the 19x11 +50.
19x11 et40 will only fit if you roll the fenders and run over -3.2 camber.
I've had both 19x11 setups, so this is from experience.

thanks, most helpful....what are the pros and cons of running the 11 et 50 versus the 12 et 63. wider tire would give me more grip? what would you suggest. looking to get a set of oz ultraleggera's. the 11 et50 is widebody fitment and the 12 et 63 is for gt3. from your response, they will essentially the same.

Wider wheel in the rear would give you more grip but not sure how it would affect steering ( induce oversteer or understeer) The only difference between the 11 and 12 is the width that affects the inside fitment, but it will stick out exactly the same. ( flush with the fender)
