I just installed the Stop-Tech crossed drilled rotors and Akenbono pads on my 435i. I got tired of the stock set up and all of the dust and noise. I will say this set up looks good and i have hardly had any dust so far. The brake feel is pretty good also. I made a quick video and posted on YouTube about my thoughts so far. Please let me know if you have any questions about this setup.

I always liked the feel/performance of the ceramic akebono pads over any other brand

Are those rotors from Stop Tech two piece? I wasn’t aware they made them for our cars.

StopTech does make an actual floating two-piece rotor for the front. It's a special order item and lists for around $1,500/pair. The other StopTech two-piece rotors that you may see are fixed (connected rigidly together like some of the ones that you see from BMW with rivets around the rotor hats).
ECS also has a front rotor that appears like it might be a two-piece floating rotor. They sell them for about $850/pair in 370mmX30mm. They have an ECS brand name painted on them. I wonder who really makes them for ECS? Anyone have any idea?

They are single piece and that's why they are a lot cheaper. Pagid offers a 2 piece like the BMW offering and rockauto got the best price on them.

I have the 370mm M Perf kit on my car and the stock pads are INSANELY dusty. I put on PowerStop z33 pads front and rear... I can now wash my wheels once every 2 - 3 weeks if I wanted with only a 20 - 25 mile daily commute.

Powerstop are complete waste of time pile of junk brake pads. They squeal like shit and the stopping power is just not there.

They are 1 piece. You can get them from Tire Rack.

I heard mixed reviews on those pads so I decided to stay with Akenbono. I have had their pads on other cars and they always had super low dust. BMW cheaped out by putting those dusty stock pads on the car IMO.

I am a perfectionist. If they squealed they'd be in the garbage. There is not ONE squeal from my car, period. I will gladly record however many hours of driving you'd like. You're reading reviews of the PowerStop Z16 pads... these are Z23 and significantly different/better.

I have about 800 - 900 miles on the pads now.

Further, I would wager $1000 that you would not be able to tell the original M Performance pads vs. the Z23 pads re: stopping power. Absolutely guaranteed. Seriously.

That's fine re: Akebono but the mixed reviews you read were surely for Z16 pads. The Z23 pads the bees knees. I don't wash my wheels now and my car stops.

I have an E84 X1 M Sport as well w/ stock brakes and BMW pads. When I drive that car I feel like I am going to go through red lights when I stop... my F30 with Z23 grab and bite so much harder. Seriously recommend them. If you're in the SE PA area feel free to come drive the car.

Yeah, I have major OCD too. So I don't understand why a perfectionist would ditch the OEM 2 piece rotors that's lighter for a cheaper and heavier 1 piece rotors.

Not sure what you're talking about... I have OEM M perf rotors on my car...

When one mistakes their ignorance as confidence...

oh sorry, forgot you're not the OP. But the Power Stop are still cheap Chinese junk. Belongs in the trash cans.

The majority of the consumables for cars these days are Chinese, can't avoid it. That said, no squeaking, stops as good as stock MP pads, and literally no dust... I am good with that. Would I run them on my other 800+ HP BMW? No, but that's not the point.
