I use this Castrol Edge 5w40 for 5 years already in my e46’s m54b30. No issues. Trying to stick to 10k km intervals.
Pros: no issues
Vehicle:
BMW
Mileage: 10000 km
In my e39 M54B30 473k km I am dumping Castrol Magnatec 5w-40.
Nothing to complain.
Pros: nothing to complain

Mileage: 473000 km
I have Pagid RSL29 pads and ATE 200 fluid on Hankook RS4s -- I don't worry too much about brake fade unless it's peak Texas summer heat, in which case I'm managing engine and tire temperature with cool down laps anyway.
Pros: no brake fade
Cons: fade in extreme heat

I would post up in some E90-specific forums and see if you can get some feedback there, or at least piston measurements to compare to your stock brakes.Like others have said, the biggest thing you're looking for is to not effect your brake bias.All this said, don't let this hold you back from getting some more seat time. Throw in some fresh fluid, maybe get the HT-10s (which I've had good luck with on track personally), and get some more days under you before spending money on mods.
Pros: good luck on track

I used OEM, Motul, and LiquiMoly oil. The only one that seemed to do anything with oil consumption was the LiquiMoly. I changed the oil every 5k miles and I had similar experiences as you until I did the LiquiMoly. Completely anecdotal, but I’m a believer. Been using it ever since.
Pros: reduced oil consumption
Vehicle:
BMW
Mileage: 8000 km
I\u2019ve had both a pre-facelift M3 and LCI M3 CS. Honestly they are both great and I think the LCI is a nice new interpretation of the halos. Alternatively, I don\u2019t think the pre-LCI needed a new interpretation. Either way, they are both better than newer version, which still look to me like they are upside down.
Pros: great new interpretation
Cons: newer version upside down

Be aware, the dimples and slots make for more noise so don’t expect them to be identical to the blank rotors in that regard.
Cons: more noise

I replaced the water pump in 3/2021. By 2/2022, it started leaking, so I replaced it under warranty. It leaked again in 1/2023, leading to a 3rd replacement. Now, one month in, the new pump is already leaking, this is driving me insane. This will be my 4th replacement in the last 3 yrs! These are GRAF PUMPS.
Cons: repeated leaks, short lifespan

My BMW X5 windshield broke on the way home from the dealership. These windshields, or the construction of the car and the pressure on the glass is a huge problem. Folks all over the internet with the same issues.
Cons: prone to breaking, quality issue
