Disappointment... in the Lack Of Tuning Parts!?

So coming from the GT-R world, where there are plenty of magzines and "Mooks" (Magazine+ Book) which are literally catalogs of tuning parts available for the GT-Rs, I've been searching for something similar for the IS-F.

Something like this:

I see these for the Civics, RX-7s, GT-Rs, even Toyota Crowns and
Celsiors (=LS400) and Altezzas (IS200)... but NOT the ISF

It turns out that, as Lexus has only been in Japan for the last 10 years, when they did begin selling them the two "new" models were the IS and the GS, which were clumped together in a lot of the Japanese press.  So I finally found this:

FYI, the LS was already sold as a Toyota (the "Celsior") and the SC was sold as the "Soarer" and even the previous IS was sold domestically as the "Altezza."

In any case, I eagerly ordered the Mook (from a used bookstore) hoping to find some cool parts I hadn't come across before on the Internet.  Strangely, no matter how hard I looked, I also could not find a "Volume 2".... ok this is not a good sign...

It arrived nicely wrapped not just in clear plastic, but also this protective foam:

I eagerly opened it up, only to find:

ARGH! My eyes!!!

What kind of junk is this? And then I really wasn't expecting anything IS-F related, but then:

Sorry, but what IDIOT would run around with these heavy cast wheels?

The other wheels they had weren't much better either, at least for me:

Yeah not for me.

It's really strange - with the RB26 GT-Rs, it was almost required to change out the wheels to something more aggressive, fatter, and bigger.  With the IS-F, I think the OEM BBS designs are all great, even though I have yet to see the versions other than the ones on my car now.

In any case, it means that, other than OEM items, I will have to rely on these shops for cool aftermarket parts, at least here in Japan.

Let me know please if there are others outside Japan I should know about!!

Meanwhile, I guess maybe they didn't make enough numbers of the IS Fs to make it worthwhile to publish more dedicated magazines and books? Although this really was Lexus' first supercar...?
