There is a difference:So now we're into a **** swinging contest over M/RSI don't know why you're getting upset about this. I like M cars a lot. I almost bought M2 instead of my car but I changed my mind last minute because six months of the year here the Audi has a very distinct advantage. All I am saying is that these cars very likely have upgraded pads/fluid. That would be true for pretty much any car used in a performance driving environment, even Porsches and Ferraris.
Almost all OE performance brake systems are made by Brembo, at least the calipers. My car has an eight pot Brembo system. So to think one brand can get away with "lesser" pads is a positive? Whatever makes you feel better.
1. You said they dust. Yes they do. It is a BMW thing forever.
2. No, it does not need to be upgraded. M cars come with already track-capable brakes, cooling etc. Actually, since F series, all BMW's had much more capable cooling systems than Mercedes, Audi, and, well, just for fun, Lexus. BMW 335 from 2012 was coming with either front Brembo (pads were Jurid, 3 types, including track capable S2NHA code. I have them on my E90 retrofit from F30 335).
3. All BMW's, regardless of engine, have brake cooling systems that in Audi's can be found ONLY on RS vehicles. M3's come with far different cooling system that actually has a dedicated cooling line, not just a wheel well opening to direct air.
4. For example, your RS comes with 370mm rotors in front, while M2 comes with 380mm, although weight is back. In back, RS3 comes with 310mm, while M2 with 370mm. Just to give you a difference.
You are assuming that it needs specialty pads. I just checked prices, OE BMW pads (without CC package, which I assume G comes with) are $50 more expensive than Pagid RSL. That tells you what you getting as RSL is usually drastically more expensive.
