That’s a pretty solid list brother. Definitely would make improvements to the cars performance on track.Don't see it ever being AWD.
What would get me spending the extra $: magnetic adaptive dampers, track-capable brakes and cooling to prevent limp mode on track, an eLSD with true torque vectoring, active exhaust. A 360 camera would be nice, rear parking sensors and cross-traffic alert should be on base model.
I'd rather have a significant weight reduction than added power.
