Just to update this thread....
First a few folks to thank, my local Lexus dealer (Pleasanton) and the staff @ B2Auto (more on this later).
As I mentioned earlier, because the stud broke INTO the lock nut, it didn't matter if I removed the spacers to go back to stock that very night since I didn't have any spare nuts (plus it didn't help that I was emotionally distraught). I did however visit my local Lexus dealer the following morning to see if they can spare me some lug nuts to replace all 4 of my wheel locks (since the broken stud was inside one of them). Luckily for me, they graciously gave me 4 as courtesy saving me a few bucks (kudos on Lexus for this one).
In fear I was out of luck in regards to a warranty claim (since my previous post showed 88 lbs), I went ahead and contacted local Ichiba distributors to get opinions and to see if they had any replacements in stock. By this time, I had ZERO faith in customer service, since contacting Ichiba directly was not possible (Ichiba phone lines appeared dead), and I was under the impression B2Auto was putting the blame on me because of my misreadings earlier. After all my frivolous calls on the phone, I ended up paying a premium above what I paid B2Auto to a local distributor, since I convinced myself that I wasn't going to let this experience bring me down and give up the mod.
With a new set of spacers in hand, I went off for a 2nd night of spacer install, but this time armed with a hydrolic jack.
I started by redoing the nuts on both front wheels (since B2AUto staff pointed out I was reading my wrench wrong) by removing them, then re-installing by hand in a star pattern, then adjusted the wrench for 50 lbs, 5 clicks, 60 lbs, 5 clicks, 70 lbs, 5 clicks.
I didn't know why at the time, but I wanted to first take off the "good side".
This is where it gets interesting...
Top: 25mm Ichiba v2 spacer from local store
Bottom: 25mm Ichiba v2 spacer purchased from B2AUto (however it was directly shipped from Ichiba HQ)
Notice how much more substantial the top (matt) unit is. Look at how thick the sidewall is for the hole that goes into the OEM studs.
Here are the 2 spacers fitted on top of each other via the center hub ring.
Top = original spacer I got from Ichiba/B2Auto order.
Here is another angle.
From initial impressions, the only direct interchangeable PART these 2 have in common is the center ring. The dimension of the outer ring is different, the bolts are different, even the NUTS were different. The larger non-polished version is also heavier!!! (granted they were both 25mm in width)
It may not be directly visible in the picture above, but the writing on the bolt heads are different, as well as how much they are recessed into the outer ring. With the original polished version, the bolts are in deeper (perhaps this is also why the over all weight is less).
Below is a picture of the nuts. The lighter "polished" version has no markings (generic one on the right), while on the heftier version, each nut is inscribed with 12x1.5.
Curious to see if the extra diameter mattered, I mocked them on the rear wheels and below were my findings..
Below is the "polished" version with the deeper recessed bolts.
Notice how there is a slight lip that is exposed on the wheel.
Below is the "matt" version with the different bolt heads.
Notice how they completely cover the backside surface of the OEM wheel (no "lip").
Similar to the front wheels, I tightened the inside bolts to a star pattern, first by hand, then...
60 lbs, 5 clicks, 70 lbs, 5 clicks, 80 lbs, 5 clicks. Then the outside bolts (wheel) to 50 lbs, 5 clicks, 60 lbs, 5 clicks, 70 lbs, 5 clicks.
Now to the BROKEN SIDE....
Here's another picture of the broken polished version where the stud was sheared off.
Here is a picture of the matt vesion installed. Can't really tell from the pictures, but in person the matt version clearly covers more of the brake rotor.
After setting the car down, I then set my wrench to 76lbs (as per the operators manual) and tightened all 20 wheel bolts.
NOW....why thank B2Auto?!
Because out of the blue I get an email from them stating they have contacted Ichiba on my behalf and they (Ichiba) will be sending me a replacement spacer. Then later today I get a confirmation UPS email from Ichiba that the spacer will be delivered this evening.
I was at a lost for words when I received those emails, so I figure what better way to say thanks by reporting my experience back to the community.
HOWEVER...since there is apparently at least 2 versions of V2, I wonder which one I'll get? And from a physics/structural standpoint of would it matter?
I definitely will try to make sure both sides are equal before even thinking of mounting them, but to whoever is reading this....which version of V2 do you think came out first?
My guess? The heftier matt version. The polished version seems to be a more refined piece, but because of the lack of material, it may not necessarily be an improvement.
