The Turbo wheels are the only forged factory wheels for the 981 indeed, and also the lightest, but my guess is not my much. The reason is they're wider than stock by 0.5" at all corners, from 8.0/9.5 to 8.5/10.0, but with the same tires. Only the Techno (non-forged) wheels are of the same width as the Turbos. I have the more desirable Turbo look, which is black everywhere except the polished surfaces, but man, they were expensive as hell. And yes, they're a bit 'busy' for those of us who like cleaning the wheels on the inside, but I'm still (barely) able to do so, although with much more difficulty. Having said that, they're the best looking wheels on a black car (like mine) IMO. But if I had the choice, I'd have gone with the standard GTS Carrera S wheels, and save over 3 grand on the 'upgrade' (ouch). But now that I have them, will go with 245/275 tires, since they're wider than optimal for 235/265s.
