Brake discs TRW or OEM BMW

I used TRW on Laguna 3, almost a year for now, no problems)

I just ordered pads, rotors and sensors for my 16 M235i. Cost out the door was $1000 for BMW OEM parts. Rotors are each unless it's bought in a kit. ($177 each) Rotors are likely smaller on the rear wheels.

I've installed drilled and slotted rotors on my pickup, BMW X5, and just ordered a set for my BMW Z3. I live in the mountains, drive spirited, and definitely have improved braking performance with them. Make sure you bed the pads in correctly.

i bought used 2011 528i RWD N52 engine with 120k km 5 years ago.

currently sitting at 179k km.

brake discs/pads/fluid

Saves energy when braking. Its really satisfying to see the range go up when slowly braking downhill. This also saves your brake discs from wearing out fast, (just remember to use the brakes some times so they dont rust).

have drilled and slotted rotors for it with pads not installed, only problems are it needs the new brakes installed the current ones are warped

Ever notice how BMW does not use cross drilled rotors. I think Porshe is also open about the fact they only use them for the looks. HMMMM

the 325 rotors are tiny and have pitiful heat capacity
