Yes, I have the MXS 5.0, hardwired indicator panel in the hatch. Its plugged in anytime i wont drive the car for more than a few days.
100% id suggest keeping it on a charger if youre going to go more than a week without driving it.
100% go through ADRO directly. You can tell by who got their stuff when that they are prioritizing direct orders. Id call them and get an ETA before you order too.
Quality of the carbon/build is good.
Side skirt fitment is 95%. Better than APR, but not perfect.
Rear winglet fitment is like 85%. A few small adjustments to the design would make it much better.
