Mine too!

But they are P101's. Starting to ponder whether I should've done the R101 lightweights after seeing these weights!

What are the wheel sizes of the HREs?

Actually... You make a good point since the 666M wheels aren't the same size. Here, this may look better with the specs of the wheels laid out:

HRE R101 Lightweight
Front 19x9.5 - 17.00lbs
Rear 20x11 - 18.40lbs

M4 GTS 666M
Front - 20x9.5 - 24.80lbs
Rear - 20x10.5 - 28.60lbs

If we were to produce a 20x9.5 instead of the 19x9.5, we would be looking at 17.40lbs per wheel.

HRE R101 Lightweight

Rear 20x11 - 18.40lbs

BMW 666M
Front - 20x9 - 24.80lbs
Rear - 20x10 - 28.60lbs

So R101LW's rears are wider, and so are the fronts, but we're down 1" from the front diameter. If we were to produce a 20x9.5 instead of the 19x9.5, we would be looking at 17.40lbs per wheel.

Impressive. Quite impressive.

Thanks for the information.

Great job on reducing so much unsprung weight, even with a 20" wheel diameter.

Is it the lighting or are those GTS 666M's in the picture? If so, the specs should be 19x9.5/20x10.5. The 20x9" ZCP 666M front wheel is about a pound heavier.

Good call. Editing that post. Thanks for catching that
