Tthe ET offset at 15mm puts the wheels to far outward for the front of a 924 You may squeeze them in the rear with the right tires. I messaged your PM about the spider web OEM wheels 15x6 they are et 33.8.





Here is what a set of 15x7 et 23 looks like on Ft of a 924 the et 15 would be 5/16" ( 8mm) further out that these are on the silver car. You can see the silver car is running the Front end jacked up so the tires don't rub.





You can see in the rear an extra 8mm ( 5/16) would be okay ) Silver car

I suspect the red car is running spacers in the rear to help the rear stick out since the fronts do.
