on their website it only shows the IS350 and LS430.
Maybe they retrofitted the IS350 ones on there?
Full set goes for around $5k (front and rear)

Them better be good brakes....edited b/c I originally thought that price was for pads only...that would have been crazy. Never seen their stuff. Anybody use them before?

these are not the same brakes as the ones pictured on the IS F
I know that StopTech supplies all of the high performance upgrades to Toyota for TRD and to Lexus for the F-Sport program.
I doubt they would retrofit the F-Sport brakes for an ISF, given the heavier front end and different weight distribution. I gotta think this is a new development. Besides, I just went on to their website and it doesn't say anything about carbon ceramic brakes. I am going to give these guys a ring tomorrow...

Stop Tech originally designed a carbon ceramic setup for the IS F labeled under F-Sport for SEMA 2007. Lexus ditched the idea after bed in issues with the pads and the rotors. Because there was a prolonged bed in process, they felt it wasn't a suitable item to warrant under F-Sport. Plus the cost of $10k and up wasn't something everyone was ready for.

Okay. So here is what I found out today from the boys at StopTech. Lexus has released StopTech from their contract for the ISF and are allowing them to supply the aftermarket for the ISF Big Brake Kit under the ST name. ST are in the middle of building kits for stock and are going to announce the release in the next few days.
In addition, ST is using an employee's ISF and their new BBK as a mule to test a new "radically different" carbon ceramic rotor, which they plan to release as an upgrade to all their current kits. Word is that their latest iteration of the CC brake will bed in within 5-10 minutes....
This means we can buy one of their kits in iron pretty soon. And, it means that we might have an option of upgrading our brakes to CC in the future.
According to the guy I spoke to Hotchkiss did a private and independent study for Lexus to evaluate all the various bits in their F-Sport line. The ST kit with the iron rotors outperformed our stock brakes by over 12 feet and gave a much more linear response. Interesting stuff...
I could not get them to give me a price. However, I would bet it will be similar to any of their 6/4 piston kits.

I wonder if they'll have 2 piece rotor replacements for the stock Brembo's? It'll be a nice less expensive way to upgrade the stock brakes, which are pretty damn good to begin with...Darshana S...
StopTech announces release of their Big Brake Kit!
I confirmed this morning that StopTech have announced the release of their BBK. It is supposedly due to ship May 1st. My brakes are almost gone at 13k! I have already ordered mine from Zeckhausen.

I will post an update once I receive my kit. I hope they ship early!

A little on the expensive side. I'd like to hear some feedback or see comparison data before purchasing a BBK though 
ISF already has one of the very best brakes in the industry. i think it would be hard to cut braking distance by much and if it only reduce distance slightly, i am not sure it's worth the expense. the OEM brakes are alreasy very fade resistent, so there is not much to be gained in that area. a cost effective alternative for street cars may be a set of wider front tires.
I'm sure they will offer the two piece rotors. I would definitely buy a set of their AeroRotors.
Any status to report on your BBK upgrade ?
I stopped by ST the other day and spoke with Mark. The Carbon Ceramic kit is still under development due to bedding issues, but should be released soon. This kit will be under their own ST name. I picked up a CC rotor, they are very light!! Big weight savings!!
I am definitely watching this thread for the updates on the CC system from Stop Tech. The pics look so impressive. Please keep us updated. The savings from not having to buy replacements of the factory rotors and pads every 10k miles should pay for this system over the life of the car. And who doesn't want the "wow factor" of carbon ceramic brakes.

The Bedding issue will always be there IMO. Its a temperature thing...and most of us will never get the brakes to the temps they need to be to bed in properly. Plus Carbon has a history of having a steep roll off on fade. A narrow sweet spot means they do not stop when cold...and when too hot they fail to stop all of a sudden. Not worth it for a DD and barely worth it for a dedicated racer. Constant maintenance. Things have come a long way with composite matrix materials that ad frictional elements at low temps but I still think its not viable for the street.
