I've got that wing. Quality is very good. I had the body shop paint match it on the outside and wraps around by about half an inch on the inside so you can see the exposed carbon weave without being too obvious.
Instructions are nonexistent, but a healthy dose of pre planning and common sense...
Dinan rear wing, which was color matched on the outside with a little wraparound on the inside. Maxton v3 front lip and Maxton v2 rear spats, both in gloss black. To my eyes, it looks very OEM+, which is exactly what I was going for.

They're even struggling to sell what is, for all intents and purposes, a new one. Didn't get anywhere near MSRP. That's pretty bad.

Website indicates that it works with the Supra (asks for VIN). Also requires a second fob that goes in the transponder mounted under the dash.
They do mention in the comments of the demonstration video that it voids drivetrain...
Just today...got the car out for a short drive, now that it's boost weather in Ohio. Started it up and it tells me, after cranking, that no key was present. Took key in question out of my pocket, held it by the ignition, and said out loud, to my car, "key's right here, are you fucking blind?"...
