You can disagree all you want, but it's Wrong...Just look up the sizing spec...It's Black and White.
LEFT Side is the important side (primary bearing), the spacer is only about .045" different and since the 00-07 calipers don't have the same pad guide as the Brembos, it's not as noticeable, but if you use a 00-07 Left spacer with a 08-later wheel that has 25mm x 15mm wide bearings, you will have moved the rotor-to-caliper alignment off by that much. Not enough for someone to say "It doesn't fit" or keep your wheel from rolling or your brakes from stopping you, but enough to put to rotor off center.
All you have to do to prove that out is measure the bearing-to-rotor mtg surface on those two different wheels to see the dimensional difference...that difference is made up by the different spacer
I measure stuff...that's what I do

Have you done the swap? If no, then see what happens when you use 08 spacers on 07 down calipers, they rub on the rotors. Specifically the left rotor when sitting on the bike looking forward. The side with the shorter spacer.
Just because a parts book tells you to change them does not make it so.
Ive measured them as well, they work if you change rotors and front brake calipers, if you do not, the spacing on 07 down is different.
My rotors do not warp, my wheels turn true and the tire is centered. I'm using the old spacers on a 12 airstrike wheel 25 mm axle and old brake calipers. This is on a 05 bike.
I have an 04 bike, with brembos, a 19 enforcer wheel and it uses the 08 up spacers.
Same front forks, both old bikes, no problems, why is that if the spacing is wrong?
Both track true, both stop very well, no tire issues and they run out as expected.
I told you it's a slight change..."Not enough for someone to say "It doesn't fit" or keep your wheel from rolling or your brakes from stopping you"
Simple question...Do you or do you NOT believe that the Left bearing-to-rotor mtg surface on the 00-07 vs. 08-later wheel assys are different dimensionally?
If you believe they are different, then what do think is used to keep the rotor alignment in the same place other than the change in spacer dimension?
If you think they are Not different, then that will be easy to prove.
So, what is it?...different or NOT different

Well, I'm boarding a
Plane and unable to go out an visually look it over to specifically answer your question.
I agree the rotors are different size the brake calipers are different from 07 down and 08 up, but as to your specific question, I would need to get my measuring device out to answer.
And I'm not, nor have I insulted you, I have responded respectfully. 😀
My experience with this swap is different than yours. Once I arrive in 5 short hours i will go measure and respond.
Dimensions don't lie...One just has to know how to Acquire, Interpret, and Apply
"Parts Book telling you change them" ...Where's that?
I mentioned looking at published spacer dimensions because when one sees that they are different widths, then that begs the question "Why?" ... then I go about trying to answer the "Why?". Kind of like the OLD (years ago) Hewelett-Packard commercial that asked "What if"
So, I already said this scenario can be measured, calced easily without "Mocking Up", but that's Theory. Now will put it to use...
The following is pretty much the exact scenario you presented (or one them)...I had a bike conveniently close for pics
BTW, I can also make that wheel work any which way...using 1" axle with 1"x15mm wide bearings (aftermarket bearings)...OR 1" x 21mm wide 2000-07 bearings with custom spacers...simple stuff, easily Calced without any"Mock Up" when you know all the dimensions

Have you done the swap?If no, then see what happens when you use 08 spacers on 07 down calipers, they rub on the rotors. Specifically theleft rotor when sitting on the bike looking forward. The side with the shorter spacer.
Btw, the left is the longer spacer of 00-07 spacer pair (or equal length if 08-later spacer pair, but still longer than either 00-07 spacer )
"Have you done the swap?" ... The "Don't insult me" was kind of in jest,...but then I started thinking about people not knowing where people are "coming from" so here's a pic of one my "Catchalls"...a small portion of extra of the axle/bearing stuff...the bearings in those bags (9267,9247, 9276, "A", "B", 9252 ABS), all torn apart to see the construction and differences. I won't bore you with pics of the all the extra wheels
