That's what I'm thinking. Then as CCB discs come down in price, and I can get the surface transforms tech, I may try out a set.

Dave are you getting the CCBS with your CS? I'm leaning towards skipping it as I believe the standard brakes are good enough. Plus the possible replacement cost. Wish we had a review of this car.

The stock 2NH aren't what I would consider quiet. I don't much care though, they're performance oriented brakes, so I don't expect them to be as quiet as a single piston floating caliper on an econobox. They look too damn good to really care IMO.

The 2NH brakes on my car squeak most of the time. However it only takes one spirited drive or a wash to make them quiet again. I think it is the nature of the performance pads.

I’m with dmboone25, I’m thinking of getting my deposit back on the CS because I’m tired of the games BMW is playing. I sold my OG M2 hoping to get a new CS but life moves in strange ways. We just bought a 26’ Airstream RV to go see our beautiful country and Canada in the next few years but for now I’m back on the hunt for one of my favorite cars of all time, a Honda S2000. Good luck to those of you that are lucky enough to get one, I’m sure it will be a great car.

Is February when US allocations will start? I'm curious if my allocation will come to fruition. Someone from Belgium is expecting delivery in April. Makes you wonder why US is always last for ordering/delivery.

I will not be getting the CCBS with my CS, especially since I plan to track it regularly. In my experience, good pads make up the main difference unless you are doing full out racing even at heavy brakes tracks like Road America near me. I also don't want to deal with the costs of ever having to deal with replacing the rotors for a nick or wear/heating in the long term. It's also a negative on the secondary market usually, especially at this price point. So it's an open and shut for me.

If you track with CCB is an absolute no no to use any traction control. It introduced too much heat. Tracking will burn through the discs unless you can keep them cool. I believe it is possible to successfully track them, but difficult. You really need a way to continually monitor disc temps. |

I know there's little to no brake dust, but that's a cosmetic advantage. Are they lighter? I've read that they're also squeaky...just seem like more of a headache than anything.

I honestly believe the delay in the USA is due to BMW sorting out international demand first and figuring out allocations. Whatever is not taken up internationally will be dumped in the USA market. Given the results of the M3/4cs it makes sense that they are more careful about country specific allocations.

They are lighter, and less unsprung weight is a significant handling advantage. However, it's still in the realm of things that the above average joe still is unlikely to notice. In regular street use the rotors can last an incredibly long time (anecdotally well over 100K), and are sometimes considered to be "infinite". CCBs are considered "higher performance" in general. This has usually been associated with more fade resistance and ability to handle higher temps, which ironically is the thing that can ruin the rotors. The rotors don't really wear out from wearing down like steel rotors do, they end up needing to be replaced from some form of outgassing from being overheated that I don't fully understand so I can't explain. A couple of the Porsche guys I know that track heavily, and plenty of forum people in the PCA world switch to steels on their CCB cars for track days, and then back to CCB for street driving. When I was looking for a GT4 and then evaluating buying a used M4 GTS these issues came up regularly, and it wasn't common to see people mention that 3-4 track days and CCBs needed to be replaced. There are a number of factors I don't fully understand around what the benefits are supposed to be past the weight reduction, so I'm not the best advocate. I've seen enough of the drawbacks, plus the cost, and I track enough that there wasn't any reason for me to go any deeper than the knowledge above on the issue. I've always been able to extract any additional bite or fade resistance I've needed, combined with streetability with pad compound selection. Brake dust is the losing battle though usually. My E36 M3 track car has TINY stock brake rotors, still weighs over 3200 lbs, and I've battled away the fade etc without issue, so I have zero concern with the M2's 15+" rotors involved.

looks fantastic, brilliant colour combo. i love the wheels too.
I'll pass on the GT4 if I can get a Spyder allocation. The only issue is the lack of available colours. Enjoy yours, looks superb ! Quote:

The rumors are that the second year run of the 718 GT4/Spyder will offer MT and PDK (and I would want the Spyder with a PDK)...so that might be an option down the road for me, ideally another gently used/CPO that I can scoop up....
