After Market Wheels

Hey guys
Has anyone fitted these wheels that are doing the rounds ? They any good ?

Seems like a smaller foot print, so likely less drag. But I'm concerned that means less grip too during carving ?

Looks awesome, but too much drifting could be a pain ?

I understand being 105mm will need to play with the gearing, and fitment for the gears (they wont fit straight on)

Any info would help.

Love my Carbon.....
