Preferred Simagic Evo Mounting Option

After many years of looking at and researching sim setups, I'm finally diving in and building my first rig, and I couldn't be more excited! I'm planning to purchase the Simagic Evo and was a bit thrown off to see that they removed the front mounting holes, as I had been planning on getting the Alpha Mini previously. That being said, I haven't purchased the cockpit yet, and can pick the mounting option that is best suited for the wheelbase, so I'm curious which mounting option is generally preferred and the most stout? I'll primarily be using the rig for drifting.

As far as chassis, I'm currently torn between the ASR 4 Open-Face and the Sim-Lab P1X Ultimate. My understanding is that the Evo with the front mount brackets won't fit within the Sim-Lab front mount wheel deck unless you turn the wheelbase sideways, which I don't love. I still need to check measurements on the ASR 4 open face to confirm it fits, but I believe it does. Also, if anyone has any input to help me decide between these two chassis, please feel free to chime in!
