Only posers
Lol! There are so many disparate points trying desperately to bond it's funny.
I don't think many are arguing the fact that drilled rotors are not highly efficient for extended track use, but it is fine for a daily driver. The poseur comment is in debate. There are a few items on the car in the same vein so why not remove them as well?

For reference, here is the progression of disc destruction over three track weekends.
First track weekend
Second track weekend
Third track weekend
Would they have cracked even if they were solid? Yes. Would they be in the "unserviceable" range if they were solid? No, not by a long shot.

Lobuxracer is absolutely right. (and if some of you have not read enough threads here, know that Lobuxracer is right 99% of the time)
So, to end all discussion. The authority in automotive performance, in their most elite car uses slotted rotors. The McLaren Mp4 12C race car for the GT3 series.

NOW back to the OP. The cross drilled rotors do serve a purpose but I don't think the heat dissaption or wet friction benefits are worth the cost at shorter life span rotors. So for posers, no. Necessary, another no.

To say drilled rotors are for posers is to call most of the supercar buyers in today's market posers.... most of them come with drilled rotors.
To not like them is fine, but to insult everyone that has them (and that come OEM on the IS-F) is a bit over the top. It's your personal preference.
They work fine for street cars and the simple fact is that 95% or more of IS-F (or any performance car) driver isn't going to track their car.
Sure they do. The 997 GT3 has drilled rotors, so does the GT2. Even the 997 Cup car has them (pictured below)

IMO if you are planning on tracking your car regularly, get slotted rotors or straight up blanks. If you're driving on the street, get what you want and enjoy the look of the drilled rotors if that is what you like. You're in fine company with many other high performance cars. No one is going to pull up to your car and call you a poser for running your stock brake rotors unless they're a jerk.

Posers may be a polarizing word.
Here's a great thread - not biased for or against drilled rotors - with input from AP Racing (a well known and highly respected racing brake manufacturer) and very Porsche specific input.
Rennsport's comments about drilled rotors from their brake upgrade page:
Here our own Kurtz documents quite a few issues with drilled rotors.
So, poser may be an inflammatory expression, but drilled rotors only belong on cars with a big budget for brakes. Just look at this forum and see how many guys bought new rotors because they said the drilled rotors looked like a coffee can (even though there was nothing mechanically wrong with them).
And here's another guy with the "poser" reference.

Some of these rotors are drilled however, so please remember that all cross-drilled rotors can develop cracks, sooner or later. Gas-slotted rotors are much more durable with a small increase in weight over its cross-drilled equivalent.

I have three spare sets of front rotors right now. The ones on the car I bought for $50 from a guy in ATL through eBay. They're the worst because they were turned, but they work fine for street. I have a used set I bought from a Lexus tech (for CHEAP) because someone changed them with over 1mm of wear left (that's 50% left!) because he didn't like the way they looked. I have my cracked set, which are probably still good for one more track weekend if I really need to run them. Last but far from least, one set of pristine new rotors from Lexus that I had cryo-treated.
So no matter what I do, I'm set for rotors for quite awhile.

If our Brembo Rotors were NOT drilled, they would last longer & also squeal a whole lot less...
Unfortunately, there are no benefit in our case.. Not to even mention Lexus decided against having Directional Drilled Rotors..
So one part number Front and one part number Rear, with holes pointing forwards & backwards from side to side.
~ Granted we have Pillar Fin desgined rotors. It still "looks" wrong.
Too Bad we never got the CCM Brake Rotor options.......

The other brake upgrade unveiled was the new Continuous Carbon Ceramic Brake Upgrade. A new generation of carbon fiber-reinforced ceramic material technology maximizes high-temperature durability and system cooling in this ultimate upgrade for the IS-F. Ceramic rotors measure 380mm diameter front and 355mm diameter rear on anodized aluminum hats. They incorporate the same internal cooling vane concepts as the F-Sport cast iron rotors, while significantly reducing unsprung and rotating mass compared to the IS-F stock brake system. Distinctively finished six-piston front and four-piston rear fixed calipers signify leading-edge technology and performance. Specially qualified performance brake pads and stainless steel brake lines are included. "Pricing & Release TBA"

Good work Dave! As the OP it too ignorant to know there are indeed reasons one would want cross drilled rotors. That reason would be to assist in reducing the effects of "out-gassing" of the brake pads. He was looking to be inflammatory in his statement and he succeeded. Do they wear faster than solid discs? Yes they do, are they still serviceable when cracked as Lobux's rotors are, YES, as per the recommendations of the manufactures they are not a hazard until the cracking has gone from hole to hole, or hole to edge of disc surface. Vrra achieved the response he was looking for.
My points were
1) there is absolutely nothing wrong with drilled rotors; for 95% of people owning them they work (and look) great and without issues. Get solid or slotted if you track your car or simply if you prefer them.
2) calling somebody a poser for having or liking them is incorrect and more importantly very impolite
. These things come standard on everything from Porsche Cup Cars to Buggatti Veyron to IS-Fs

so as long as i dont race my ISF at the track every weekend i should be ok? You guys got me worried. Its the first time i heard anyone diss on a set of drilled out rotors. On a side note, Ive had these Wilwoods on my Tahoe since 2008, pulling around 1500lbs of stereo equipment and rolling on 26" wheels.....they are in perfect condition still. I know its a lexus forum but were talking brakes, so here is a few pics of the monster 16" set i have on the 'hoe. They are cross drilled and slotted.
I guess im a "poser" then lol

this one has 2500lbs of stereo equipment and 26" wheels....did the brakes around the same time, and its the same set i have. No problems there either......

so is it just hardcore track use that rips them up?
by the way, that video isnt just a cheap attempt to get you to watch my video of the escalade i built, the ISF makes a few appearances in it too so its not totally off topic haha! we were talking brakes so i thought id post this up.
