Does anyone have these OZ's on their car or had them on their GT3? Im looking to buy a set locally and wanted to know the proper offsets and tires sizes for 19' to avoid rubbing issues?

I was told that below is the proper size:

19X9 w/ 235-35-19 et 43
19X11 w/ 315-25-19 et 58 (IS TIRES TO WIDE or are the "305")

Why 19's?

Im getting a deal for them brand new, thats the only reason.

Lots of good reasons not to get 19's, but to each his own...

On those offsets, they fit. I would rather use the Porsche OEM 5mm spacer at the front to get the offset to 38mm, but it's not needed.

The 315/25R19 MPS2 is as wide as the 305/30R19 Porsche N-spec. The 315 has the same load rating as the stock 18" 295/30R18.

The tires combination has about the same rolling diameter as the stock 18". No changes in gearing.

I've been running 19" x10" and 19x11.5" for around 8 months with 265/315 MPS2. I did two track events with them, some auto-x and plenty of street miles. The car got a 3rd place at a recent Concours .

Just remember that the 19" have stiffer sidewalls, so the ride gets bumpy, you need to adjust the shocks to compensate. Forget about shocks adjustment, if you have stock shocks.

My 19" bricks weigh 27 lbs and 29 lbs, an increase of 10 lbs on unsprung weight, but the PCCB saved 42 lbs.
