Ok.
The fact that they SUCK and need to be upgraded is the main concern/reason for getting/trying this set which other M guys recommend. Infiniti failed miserably with the 06-10 M brake capabilities for this size car. The G has good brakes. The M? No.
Ok.
Let’s relax and go buy some parts for your BMW and post in here and get off my back about what brakes I choose to buy. If I spend $180 on a set that just so happens to be drilled and slotted but performs better than OEM…whether or not I actually need them or whether or not it actually looks good…I’ll buy them again and again. Who gives a crap about the rest of it? It’s not like I just shelled out 1.5k for a BBK which I don’t need because I’m not auto-x’ing etc. Seriously…what’s the big deal?
Damn.
Because me having a BMW has ANYTHING to do with this? Sounds like someone got their panties in a bunch because someone was trying to educate them. The OEM rotors would have been more capable whether you or your buddies think so or not. It’s pads that make the biggest difference. Due to your new rotors, you’ll just be eating through pads quicker. I don’t think anyone on this forum needs a BBK unless it’s a full race car. There’s no big deal, you’re just making it out to be one by attempting to justify your need for your drilled/slotted rotors by talking about your spirited driving or how they don’t warp like the OEM rotors and such. At least do some research on them, and don’t just follow the boy scouts over on your M forums. About the only real benefits of a slotted or drilled rotor is (this can also be a disadvantage) the increased pad wear because the pad surface is being ‘refreshed’ (cleaned) when the brakes are applied.
