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
The aspect ratio for tires is a percentage of the tire width, so while our recommended 275/35-18 and 305/35-18 tire sizes utilize a shorter "35" aspect ratio, the additional width makes for them to be quite close to the OEM rolling diameters. With so many variables to consider, such as specific tire compound, suspension setup, etc, it is difficult to say if there will be a noticeable difference in ride comfort and compliance between both tire setups. However, those sizes will be slightly more stretched on our 10" and 11" wheels.

While you can technically run the 265/40-18 on a 18x10" ET25, I recommended the 18x9.5" ET22, as that wheel size will fit the 265/40-18 a bit better. Also, with the 18x10" ET25, you will need 5mm front spacers to clear your B16 coilovers. Whereas with the 18x9.5" ET22, you will not need any spacers to clear.

If you have any additional questions, please do not hesitate to reach out!
