I haven't seen a detailed write up of Semi Solid Forging, but from the descriptions I've read it isn't quite forging IMO. The main difference appears to be the High Pressure used in true Forging.

True forging take a high solid billet piece of aluminum (which may have some impurities) and presses it against a die at very high pressures. It's that pressing (high pressure) that causes the granular structure to change and the impurities to disappear.

SSF takes a pure billet (with no impurities) and melts it into a casting. It sounds like they "low pressure" cast the molten material into a mold that forms the wheel. It's hard to tell from the description, but the "high pressure" aspect seems to be missing from the SSF process... that's why I'm hesitant to call it a true "forged" wheel.

I'll be honest. SSR is one of the top wheel manufacturers, up there with Rays, BBS, Work and Enkei. Definitely a high quality wheel.

And to be clear, SSR is they're definitely NOT playing on words like some companies are with the term "Rotary Forged"...
