Hey all, I have been trying to find the answer to this and cant see to find it exactly.
I have a 2015 Turbo and I have a few questions in regards to the wheels...

1) Will the 991 turbo (which comes stock with 20" wheels) be able to take 19 inch wheels?

2) What is the OEM sizing specs of the 20 inch wheel (diameter, width, offset, etc...)?

3) What will it take to when searching for a aftermarket wheel to get the wheel to line up with the fender or stick out just so slightly?

4) What are the OEM wheels weight?

5) Are the wheels attached by studs or bolts?

Thanks

1. If you don't have carbon ceramic brakes then 19" wheels are doable

2. OEM turbo wheels are 20x8.5 ET51 and 20x11 ET56

3. Use a wheel offset calculator such as this one to find out 1010tires.com offset calculator

4. Take your wheels off and weigh them, then subtract the weight of the tires found on tirerack

5. M14x1.5 R14 bolts. R14 is the radius size of the Porsche's ball seat bolt. Aftermarket wheels not made for Porsche may have cone seat or different size ball seat such as R12 like Audi...
