Spacers don't effect wheel bearings any more than a wheel with
So the choice for LR4 owners is adding 30 mm spacers OR shaving the calipers a little? Mmm... Does not compute.
Also, I understand that steel wheels are all about function over form, they are inexpensive and it's always great to have more choices, but... Hot damn, those are some fugly wheels.

Perhaps they'll look better mounted on the car.
The spacers or grind conundrum is the same story with the 18" Land Rover wheels. Scott Brady was initially going to grind to use the LR 18's on the Expo Portal LR4, but decided he was going to have to grind too much for his liking and went the spacer route--he said it could be done, he just didn't want to do it. If these require less grinding than the LR 18's, it could be a viable option.
Oh, and what's gold for some isn't for others, and vice versa. I think these wheels look a lot better than the Compmotives, which have always looked
way too boy-racer for my liking, especially with the obnoxious logo on the spoke. It's the main reason why I'm still rolling on my 19" wheels: don't like the way the compmotives look, and don't like the idea of spacers with the LR 18's (even though I have a set of 5 of those wheels in my basement.)
I'd like to know (1) how much these new steel wheels weigh, (2) how much grinding is required to get them to fit on an LR4, and (3) whether these steelies are compatible with the TPMS.
