GTC01s finally purchased!
Okay guys so years after I started this thread, I finally pulled the trigger on GTC01s and waited 9 weeks to get them from Japan. And today they went on the car!
The available 17" front options are slim now, they've dropped them down over the years.
I went with a 17x7 45 offset for the front. For me this is the best, because the 215 tires I have look great on them. Anything wider and they look stretched, which is not a look I am going for (I know a lot of other people like it though). And the wider 225 tires don't play nice with TCS.
On the back I went with the 18x9 40 offset, with 265 tires. Tires look nice a meaty and also not stretched at all - AND the rear fitment is perfect in my opinion.
I weighed new and old as well with an old bathroom scale in my garage.
Front setup (just wheel) is 17.1 lbs, wheel and tire is which is 35.1 lbs and is 3.5 lbs lighter than the old setup.
Rear setup is 47.6 lbs per side (wheel and tire). 1.5 lbs lighter than old, even though I added 38.1mm of wheel width and added 30mm of tire width. These are light wheels.
Looks like I took a good amount of unsprung weight out of the fronts and added a crap ton of traction to the rear and still took out 1 lb a side there.
Old wheels on the car - these are Chinese cast wheels with the universal 5 lug pattern.... ugh.. Disgusting. XXR something. Looked okay from 30 feet away, but they were curb rashed quite badly and the rear size was only 18x7.5 with 235 tires.
Previous owner is completely responsible for these.
New wheels!

too distracted by the wheels
