1000M wheels are 20x9.5 +20 Front and 21x10.5 +20 Rear.

Front might just barely clear stock strut spring perch depending on tires, but will extend well past the vendor. If you're on coilovers with adjustable top hats, you may be able to add enough camber to fit them under the fendor. Maybe. May require slight fender pull or over fenders too.

Rear is even less likely. Again, larger diameter, much wider, and significantly lower offset. Some folks here are running 10s or 10.5s - using A91 Supra specs - but offsets are in the high 30s or 40s. Another 15-20mm poke isn't going to work without a lot of camber or over fenders / fender flares.

All said, might work if you're supremely motivated, depending on your goals. For large majority, it will not work.
Great information and I fully agree. I am currently running custom wheels & tires (Front - 20x9 ET25 245/35/20 & Rear - 20x20.5 ET45 295/30/20) with coilovers and there is absolutely no room in rear; had to install a 7mm spacer in front to ensure roughly 5mm clearance between the coilover spring and the tire / no spacer in the rear.

I know folks who have installed 21' wheels but like you stated, what are your goals and how much are you willing to invest for a set of wheels. For what its worth, the OP should grab a set of wheels that are of similar design, in the correct size & offset for the G20 and call it a day; but hey, different strokes for different folks
