Wheel Spacers 101

Bonzo

Which part are you talking about? The part about the bearings is exactly what I was talking about in my post above. There will be more wear on the bearings for certain, I guess I'm just wondering how much. I don't want to have to be replacing bearings every 50,000 miles.

As for the the other stuff, no clue.

I know on Subarus, spacers caused premature bearing failure often. However, the hubs and bearings on them were weak and undersized to begin with and often failed completely stock. So spacers do cause accelerated wear, but on a bearing that's not a problem the question becomes "how much accelerated wear?" If it would have gone 250k without issue and now will only go 200k, that's probably ok. We just don't know. There haven't been a lot of reported failures. I won't run them but plenty of people seem to have no issues.

Exactly. If no spacers gets me 120,000 and with spacers gets me, 115,000, that's not a big deal to me. But if no spacers is 120,000 and with spacers is 80,000, then that's huge. Thing is, the guys who put on spacers aren't typically going to be the ones jumping on the forum talking about how their bearings failed prematurely. That's the only way we are going to know.

If Nissan had only designed the car with a 1" wider stance on each side we wouldn't be having this discussion, and the spacer business would plummet.

I agree that if the wear is even 10% faster, who cares.

As for Nissan making the stance wider, (again forgive my ignorance,) but that means Nissan would have to make the axles and hubs/suspension assembly longer, not wheels wider (same question I posed in the post above)

Correct. This generally happens and doesn't happen because to save money auto makers use common platforms for different cars, and changing that costs more money. I'm not familiar with how many Z parts get shared elsewhere (I believe the Infinity 37 is the same?) in particular, but I'm sure that was part the decision to stay a bit narrow. Just pure speculation on my part though. I've been off this forum so long I consider myself way out of the loop anymore.
