I think there may have been some fallout over not offering CC brakes and they may be implementing a brakes package. |

I'm real curious...a little Devil's Advocate work, here:
- Some racing series do not allow CCM disks. - Most racers (esp. Porsche) ditch their Carbon brakes for iron replacements for track days due to wear and price. - They cost a ridiculous amount of money to replace...and they're brittle while servicing. - Different compound, more aggressive racing pads are more readily available for iron brakes. - The '14 Z/28 (with CCM brakes), at 3858 lbs, stopped from 60-0mph in 97 ft. - The '18 ZL1 1LE (with same-sized iron brakes), at 3837, stopped from 60-0mph in 91 ft. GM/Al have said they didn't see a benefit to using the CCM brakes in either fade resistance or braking distances, so they couldn't justify the cost in utilizing them on the car. So why do we consider these brakes worth anything other than a party piece? :iono: |
Nicely Said!
Also unless they are heated up, they will not perform correctly and make tons of noise. Quote:

A ZL1 1LE level Camaro, plus CCB, plus whatever other upgrades it will include will cost what....$85k? $95k? Eek. |

I knew a few didn't allow them, and since I don't know all, I sort of extrapolated. A dug up a couple of other references that are pertinent, too... Written in 2014 or '15 http://www.motortrend.com/news/20-be...nces-recorded/ 2015 Z06/Z07 (with CCM brakes), at 3533lbs, stopped from 60-0 in....91 feet!!! ...exactly the same as the much heavier ZL1 1LE....just sayin'.... |

These guys aren't technically "racers", but a Porsche group runs every month during the summer at PittRace. Several are pretty hardcore guys with $500,000+ invested in their cars. On multiple occasions I've ran my ZL1 with them (because they usually don't have enough Porsches to justify the track rental). I don't recall a single person who has swapped their carbon brakes for iron. They pretty much all are running carbon ceramics. With that said, I've seen many Viper ACR owners go back to iron brakes. If you talk to them, their reasoning is almost always cost. Quote:

Was iron the right choice for the ZL1? I don't think there's any question. For most people iron makes way more sense. With that said, I am very excited to see that CCMs might be coming our way as an option! As long as the price isn't crazy, I want to try them. |

Given that factory tires are roughly $1,400 a set. The overall maintenance cost of the brakes should at least be comparable to the overall cost of tires. That's all I meant. |
It would make sense to create a Z/28, mainly based on the fact of a 5.5L coming. Why? The Cadillac DPi’s just switched to a 5.5L (hmmm...). The next Corvette will have a 5.5L (hmm...). The GTLM/GTE Corvettes run 5.5L’s (#muchdata #proven). With that, it makes sense to homologate to the GT4 Camaro, which opens up a business case for the option to create a Z/28 road car. Right now, the GT4 engine is a GM Performance/GM Racing frankenstein. Cost, complexity, durability and marketing wise, it’s a better move to go with the Corvette C8 5.5L.
Take a ZL1 1LE, remove the LT4 and shove in a 5.5L DOHC, or even HOHV, you reduce weight. Remove the rear seats, strip down the creature comforts... With a 5.5L, you get a more stabil engine for high RPM. You can still get the power performance needed through a shift in the RPM band. Also, a 5.0+L V8 is still large enough to get good mid-range torque. A 5.5L also helps in pro racing because a 5.5L restricted is more efficient and stabil than a 6.2L (BOP - heat management/combustion efficiency) and fuel economy is better. So, a 5.5L also makes sense for the race cars. |
