Sorry, that 15mm is total thickness, including the frame thickness of 3.4mm. That would make the spacer 11.6mm thick.

If the OEM Toyota spacer is close to 9mm as someone said above, would a new 11.6mm spacer make any real difference? I mean 2.6mm seems pretty meah to my untrained eye. This for the LC crowd. I know nothing about LXs.
I stand corrected on the flange nut threading. As it's an M10 stud, minimum threading should be 1-1.5 of base diameter (8.16mm), or 8.16-12.24mm of thread engagement. Westcott seems to be in the right ballpark with a 13mm spacer.
Looking back at my setup with the OEM LC shock spacer, this was the AHC bracket clearance and remaining stud. Seem like it'll just top out everything and perhaps may not need any AHC bracket grinding? That may be the way to go for a more drop in approach.
Good point and this is probably to differentiate a product from the conservative OEM spacer (0.8" lift). With a 13mm spacer (4mm) more than the stock solution, that would mean .3" more lift, and .3" more suspension suspension travel. Or about a 1.1" total front axle lift (LC), or hydraulic compensation (LX).

Does anyone know why the factory spacer has this notch in it?
Likely so it doesn't trap water and dirt
I guess it will allow a little less build up. I will add that cut out to them. I can sell a set for $100 including shipping to the lower 48. I can have these ready by the beginning of February.
As promised, 1st in line! I think I might have been the first with your rear lower shock relocation kit too 
I’ll be 2nd in line. Although I better install something soon. I have OEM spacers and some questionable 20mm spacers off eBay. strangely enough “Temu” branded, but I dont think related to the Chinese Amazon comp. They are made of some sort of rubber/plastic.As promised, 1st in line! I think I might have been the first with your rear lower shock relocation kit too
I havent installed either yet. But will be doing something soon as I have e to take apart my passenger side anyways.
How much do we think can be gained by using new studs? I get the drop in benefit, but I don’t mind the extra work to change out studs.
I'll put a pre-order page on the site shortly.
I also made a quick print to make sure I got the hole spacing correct. Wish they would make things symmetrical.

That is a super conservative assumption is it not? If nut and stud are the same strength you can go 1/2 of diameter for nut thread engagement or if like most applications the nut is softer to spread the strain axially you can go to 7/8 diameter engagement and most standard nuts are under 1.0 dia.
1.5 dia is a ton of engagement unless you are putting a huge preload into a system that needs it (and then you wouldn't put an aluminum spacer into the system?).
Since standard grade 10.9 M10 nuts are 8.4 mm thick, I don't want to sell something with less thread engagement than that.
I mentioned in the LT AHC thread that I could make new shock top hats that would use bolts instead of studs and be able to add spacers as needed. I forget why I didn't make them, but this is still on the table if there is interest.

Ultimately, I chose the Westcott because I wanted to stick with the OEM studs and, although I understand how others feel comfortable with 20mm and it’s benefits, I personally wanted to keep my CV angles as flat as possible. Especially considering the “disease” I suffer from regarding tire size. I’ve seen @TeCKis300 mention a safe CV angle, but I figured the flatter I stayed, the longer my CV’s might last with ridiculously oversized tires.
Pic of it in AHC low since this is that thread…
For those considering more reasonable tire sizes, like a 35, I could see trying to maximize the top spacer to closer to 20mm.

Well, I think every 570 should be on 37’s, but if that seems like too muchROFL. Quote of the year 2025
then a 35” at least. Reference of how stock a 37 (posing in high) can look…
Miss seeing pics of this rig! Looks the business.
