Agreed on that...

Also, if you do some research slotted works best for actual braking purposes. Drilled does dissipate heat as well, but not as good as slotted

there is more to the CSL/ZCP brakes than holes. as for the rotors they are lighter and also have a floating hat design with the center hubs being aluminum. i don't see anyone saying this part of design is a "gimmick".

Do more research. See what rotor people use for "tracking purposes" because BBKs and brake upgrades are for "tracking" correct?

The thread isn't about tracking, keep on topic.
I keep asking specific questions and you keep dodging them. 1) you either don't have the knowledge about it 2) you avoid the answer as it contradicts your posts

What's the gimmick?
Is the floating hat design a gimmick with no benefits?
Are lighter aluminum hats a gimmick with no benefits?
Are the larger front rotors a gimmick with no benefits?

This is my move on the situation, the person wants CSL rotors and I simply believe slotted rotors work better. CSL style rotors do not work as well as slotted rotors. The gimmick here is that people buy CSL rotors because they look nice. Thats what I think, I am entitled to an opinion.

i agree that there are better pads and rotors for track purposes.

i see you once again dodged answering my question.

if you're now stating your opinion is that bmw made the rotors for people to buy because they look nice and are a gimmick..that's an opinion.

but...if you're saying the things i pointed out about the rotors is an opinion and not a fact (of physics) that it's of benefit then you're mistaken and saying it's a "gimmick" is misleading to anyone who reads the thread. and we're here to promote the best information possible right?

and your point that some other rotors are better is well said.
i only had issue with posts they are a "gimmick" and "show toy" which i have listed reason they are not. sorry i hope i didn't come off harsh Donovan.

I am glad we sorted it out, but I love a good internet rumble lol..
Yeah man I know that REAL CSL/ZCP rotors have a definite meaning/use to them, of course they do...lol.

I mean **** I wanted a BBK at "first" because I thought they looked really nice, until I luckily became knowledgeable on the matter and I am currently working my way up to a better braking system...

I now run stoptech system all the way around slotted rotors and stoptech pads and they are sick on the track and have minimal fade However I am now going off topic, which I do that very well.

SQUIRREL! haha

They do? I had a ZCP and a std M3 and they seemed to be identical..? The only thing different with the brakes were the 1" bigger front rotor and that they were drilled. Not doubting you at all, just curious as to where this information was sourced?
