I'm assuming that the 285/40-19 size you listed was a typo and that you would want to run a 285/40-18, considering the OEM 513M wheels have 18" diameters front and rear.
If that is the case, I would recommend the following fitment for your application:
Front: 18x9.5" ET22 with 265/40-18 tires
Rear: 18x11" ET44 with 285/40-18 tires
Brake clearance: SB
Available in EC-7, FL-5, and SM-10 designs.
While the tire sizes you listed are a touch on the taller side, this setup should provide a direct fit on a stock F8X. If you are interested in running alternative tire sizes, these wheels can support up to a 275/35-18 front and a 305/35-18 rear as a complete direct fit on a stock car.
If you have any additional questions, please do not hesitate to reach out!

Perfect! Yes, sorry that was a typo, as both front and back are 18 inch. I like running the 40 profile tires for the side profile and comfort. Do you think there would be a change in comfort if I run the tires on my OEM 513m wheels and your wider Apex setup that you mention above? I'm assuming going from the OEM 513m front 9 inch to your 9.5 in and rear OEM 513m 10 inch to 11inch Apex setup will stretch the side profile so it will not be as fat and comfortable? Or am I just over thinking it?
Oh and can I possibly run the 265/40/18 front tires on your 18x10et25 wheels? I have about -2.7 camber in the front and -2 in the rear running the Bilstein b16 coilovers
