Updated info from
@hml_xy who took photos of the inside of his wheels on his new Emira (Germany).
Stock wheels on the FE (forged) are the following spec:
Front: 8.5x20 ET 57
Rear: 10.5x20 ET 54
Manufactured by Dicastal (US) in China.
Other markings indicate they are forged from 6061 aluminum though oddly it doesn't indicate what alloy, which would be useful.
The front are rated to to 460kg, rear to 685kg.
FYI these are significantly different specs (particularly in the rear) compared to the Evora GT. With the lower rear offset they should be much easier to source aftermarket wheels for, compared to the +69 offset on the Evora in 10+in widths.
