Looks like there's 1 more set as of 4:25p CST. Very good price and they're forged.
OP: They should look ok and will be about 15mm more aggressive than stock front and rear. Assuming you have center lock, which I think you do.

Funny you should mention that. I was considering having them done in Carmine Red to match the accents on my vents and rear diffuser.

GT3 RS has a 21x12.5" rear and takes a 325/30 tire. GTS stock uses 305/30 rear tire. The former has a 26.68" overall diameter, vs your stock 27.2" diameter.
Assuming the tire fits, that diameter change will result in your speedo showing ~5% slower than actual speed.
I don't know Porsche's well enough to comment on what else this may impact.
If that's OK with you, and assuming the wheel will fit in the first place, do it! I love the look of the GT3 RS wheels. I'd have them powder-coated black or platinum myself; they look a bit too blingy to me in silver, but that's a matter of personal preference.

The GT3 RS's wheels are 1" wider front AND rear, using the same tires. So it's a wash as far as tire diameter goes. However, the offset is 15mm more aggressive front AND rear on the GTS. The rear will look flush, but the front might stick out a bit.
