What's the difference between lug pattern and bolt pattern? As per you calling me out earlier on calling the bolts "lugs" you would be referring to lug nut pattern and not the bolt pattern and I'm pretty sure bolts have no pattern until they are attached to bolts........
From what I've read, the term "bolt pattern" is considered to be the same as "lug pattern" and is used interchangeably.
These both refer to the diameter of an imaginary circle that encapsulates the 5 studs. In other words, it measures the distance between the studs.
So in our case, it's 5x105.
When I say bolts, I refer to the studs attached to the hub of the car.
(although in retrospect, I guess the term might not be completely accurate because European cars tend to use "bolts" that just screw onto the hub, vs our US/Asian cars that have "studs" that you screw "lug nuts" onto.)
When I say lug nuts, I refer to the nuts that you screw onto the studs.
When I hear someone say "lugs" by itself, I usually presume that they're referring to the lug nuts...(I've only heard the terms "lug nuts" or "lug bolts". Can't find anything that's actually just called "lugs")
Edit: Just looked into it a bit more. Apparently lug nuts/bolts are simply what keeps the wheel on the hub/car. (our cars use lug nuts and lug studs, while most European cars use just lug bolts)
Lug nuts:
Lug nuts with lug studs:
Lug bolts:
In other words, when one says the word "lugs", they refer to the item (nut or bolt) that is used to hold the wheel (or in this case, spacer) onto the hub of the car. Or at least that's what it seems like. I'm just used to saying lug nuts, lug studs, or lug bolts. lol
The reason why I noted this earlier is because it's not the stud that's attached to the hub of the car that hits the wheel. (because as you mentioned before, Preloader made the holes WIDER, not DEEPER) It's the nut that screws the adapter onto the stock bolts that protrudes too far and hits the mounting pad of the wheel.
Sorry if my wording is a bit confusing. :/
Hope that my logic makes sense.
