I just received my Mk900bt too and just did this. The only difference is it's not called ASE but ASC on our Z with the Autel. Was able to switch it off with no issue with the instructions above.
thats actually not bad. I have Tein Coilovers - about 1.25" drop all around and my front Camber is -2.1 and -1.8, with Toe at 0.02/0.03
Im a bit concerned with my rear camber at -2.8 both and toe at 0.13. And the rears have the Rear Z1 camber arms that the shop said it help "very minimal".
The grill looks good on both but the new bumper/grill does look a bit better. I honestly wished they redesigned the headlights to be more aggressive looking vrs the current look.
