It's amazing that this can be done with the precision/thickness needed for wheels.
It's a little more to it than spinning a water dish.

That's pretty cool.
When I was in the lighting industry, they had numerically controlled spinning machines to make architectural downlight reflectors, but they were starting with sheet stock and didn't use heat.

Cold forming works just fine on some 2000 and 6000 series alloys when they are in T-2 or so. Thin enough and they don't heat up and work harden. Cast wheels are made of A356.2. They're not heat treated at this step. Later they're brought to T6 condition in baths then final machined then paint.
In theory at least a wheel of 7075 T6 would be really strong but it doesn't flow. So any wheel from 7075 would have to be cut from billet. Billet wheels cut from forged blocks have stress risers all over and tend to crack over time. Near net die forged requires the alloy to flow hence the use of 356 series alloys. Rays used near net forging in several of their wheels. So the blank looks more or less like our casting blank. Very little final machining needs so stress risers can be controlled or eliminated. TE37's are nigh indestructible for this reason.

Super interesting! Are they coated and painted at the same facility, or is that done elsewhere?

So basically 6ULs are made by robots with flamethrowers. Could they be any cooler?

Explains the $800/each price point.

Who needs 15x12's? What we really need are 15x15's.

No.

TWS

TWS Motorsport T66-F - 17x9.0J +37 / 5x100 - 56.1mm Bore - BRZ/FRS Competition Spec


TSW wheels aren't that light. These TWS wheels are even lighter than Weds/Volks/etc.

Weight = ~7.00 to ~8.00kg
More like double RPF1's weight, unless that website is wrong.
