Nice post, but thought i'd share some tips.
I've covered this in the IS sub section but installing ceramic pads in place of the stock F Sport german made high friction pads is a downgrade in terms of performance. Just as long as everyone is aware of that and is fine with that. If Lexus could retain the same performance while reducing dust (as well as every manufacturer for that matter), they would've done so already. Dirty loud screechy brakes has been a hallmark of performance cars for decades.
Porsche, BMW, AMG, Ferrari, etc. all experience the same dust and wear.
There are no free rides. No free lunches.
No real performance benefit as well to install vented rotors on a less performing pad. So you are decreasing your friction and reducing the swept surface area on the rotor effectively reducing your brake size. double downgrade. Again as long as people are aware of that and are fine with it. Yes it will reduce your dust but there is a penalty to pay, as with most things in life. That penalty is cold bite, fade, heat management and overall stopping ability.
It'll stop fine, just not as good as stock (F Sport) pads.

I would be curious what the actual stopping distances between the stock F Sport pads and the Akebono pads.
Fade kick in, etc.
Of course, the same car should be used, as tires actually stop the car, not the brake system.
I would find this very interesting and helpful, especially because I believe my car has been converted to the non-F Sport front brakes by the dealership.
I have not had a wheel off to get a good look.
The braking in my car is very good. And there are a lotta crazy drivers in Silicon Valley...
Thanks for all the great information.

I think a common misconception of "less dust" from ceramic pads makes some believe that because the pad material is wearing less, it must mean the braking performance is reduced(softer materials are usually associated with having higher coefficient of friction). In fact, they could be generating just the same amount of dust, but the wear materials on the ceramic pad may simply not adhere as easily to the wheels as semi-metallic wear materials - again, this goes back to chemistry.

Well I have insane squeal now. Trying to figure out what steps to take to reduce the squeal. I remember having the same squeal a little after putting Akebono pads on the stock two piece rotor. Forgot what I did to help reduce/fix that issue.

I just installed StopTech rotors and Centric 105 Ceramic pads, the squealing is insane, very loud. I put some grease on back of pads and did some 40-10mph runs to bed them in, but squeals is still persistent. Just ordered some Akebono pads, hope those are quieter.

So can I install this on my non f sport awd version??

Sorry to bring up old thread. Do you mind sharing how you bedded your ceramic pads?

Ideally according to Federal Motor Vehicle Safety Standards FMVSS 105 and FMVSS 135. It indicates 200 stops to completely bed in brakes, but here is an initial bedding procedure. Make approximately 20 “Complete Stops” from 30-mph - OR – 20 “Slow-Downs” from 50-mph to 20-mph with light to moderate pedal pressure NO PANIC STOPS Allow at least 30 seconds between brake applications for the brake pads or shoes to cool down It is critical to follow cool down procedures to avoid damaging NAO, Ceramic and Semi-Met friction material as well as the rotor/drum No high speed stops and/or braking under heavy loads before 200 stops that could result in glazed or otherwise damaged linings

I contacted the seller, this is what they advised me to do. Already did all this still squealing like crazy.

Thank you for your inquiry and for choosing Akebono Euro brake pads for your BMW. On the question of bedding procedures: We do not believe any special care needs be taken after the pads are installed especially if your rotors are new OE quality, or the existing good condition rotors are used at the time of new pad installation, as long as the rotors have not been resurfaced with a brake lathe. Akebono pads are fully cured during the manufacturing process and there are no "green" resins or binders at the surface as you might expect with other aftermarket friction materials. Our manufacturing process is unique and not shared by other aftermarket manufacturers.
If your rotors were resurfaced it is possible that the finish is now outside of OE specification for smoothness (Ra 15-30 microns) and you may not realize the full bite potential of the Euro pads until that smoothness has a chance to re-form and a friction transfer layer has occurred. The transfer layer usually appears as a blackish finish on the rotor surfaces, and should be very polished in appearance. This event will feel like a bedding procedure but in fact it is rotor burnishing procedure. There is no particular Akebono recommended procedure required and it will happen naturally, if you will.
I hope I have been able to address your concern. Please feel free to ask for more information should you need it.

It does specifically list the Euro pads but I'm not sure that the Lexus one's would be that much different.
