What's wrong with this picture?

Yes, they are 10's and 11's, but looking closely there's something else a bit odd.

I noticed the 11mm offset difference and they weight of ~18lbs each

11mm offset difference? Difference from what?

Clue - it has to do with the weight.

OEM front wheels, according to Google, they are 28mm.

They're lightweight? 18lbs is pretty good for an 18x10 & 11.

OK, now I understand the offset difference, but that's not it.

I happened to see it instantly and asked why? Clue - has to do with weight.

Ah, the 11" is lighter than the 10"

I even work in engineering, with the worst reading comprehension.

Bingo!

I asked why and was told, "you said you were buying these for track driving, so we beefed up the strength of the front wheels".
