want to understand if aftermarket options are comparable in weight anyone?

also the similar blacked out Edition 1 ones with R19F/R20R?

 

Good question. A question that should be asked by anyone considering a change to aftermarket rims. An expensive wheel doesn't mean a decrease, often an increase, in unsprung weight.

 

exactly i am not only after the looks. strange i cant find this info anywhere in OEM sources

black edition 1 wheels i am after have these PNEdition 1

Front Wheels: 9Jx19 ET25 (p/n A2054015900 7X21) 255/35 ZR19 96Y

Rear Wheels: 10.5Jx20 ET57 (p/n A2054016100 7X21) 285/35 ZR20 99Y

 

285/30 ZR20

 

I can confirm that the 20" 10.5" multispoke wheel (titanium and Himalayan grey) for a coupe rear weighs 25.9lbs with no tire.

 

Thanks! So 11.8KG roughly

 

Very difficult to find weight of the rims online - judging by this (random) thread it is also very difficult to find any lighter wheels

Because I had mine off I took the opportunity to weigh them.
Front 19x8.5 and Rear 19x9.5 both weigh 22.6lbs. To my surprise the same weight. I measured a few times and they came back with same weight.

Cross-spoke OEM sedan rims. Part number on rim: 37619 and 37620...at least those are the only numbers I could find on the barrels.
