Just to add to this discussion I had quite a few instances of Ice mode hard brake pedal with minimal actual braking force yesterday at Pitt Race TNiA. I attribute it to the Kumho ACR tires not having a sidewall (295/25R19s) and slight braking bumps on the track surface. I found that i had to not jump right on the pedal with full force and if i eased on then pressed hard i had no issues. Not confidence inspiring when trying to threshold brake I'll tell you that.
I had only run half a session on these tires before at Nelson Ledges when a belt separated internally on the one tire, so this was really my first experience with them. |

Yep that's the study. They reported % of water content found as part of the test. I recall seeing 2.2% in some cases? Sorry no time to verify as i am in a very long transit now (to hopefully see my new car!). Agree that there are other solid choices besides SRF. But even Essex pretty much agrees it is the best Cheers! |

No new PB at Pitt at least not that i know of haha. I didn't even run track addict as the temperature was 95+. I will say the ACR tires definitely felt more grippy and handled the heat better than G3s, but they even still got greasy being that hot. I do have a new PB from Nelson Ledges time trial Sunday on G3's however I'll get the video ready and added to the track times thread. |

Although the video is Corvette C8, what they’ve done for the brakes, and why, is very interesting.

This is a great video! Interesting that brake by wire, can effectively give you more pedal travel to compress air in the lines to give you more brake than you normally would have. I would hope there there would be a warning to the driver to change the fluid. Many of the C8 reviews kind of complain that C8 understeers, but the street -0.5 camber vs -3.0 track camber could explain it. I wonder if the cars being tested had the street camber. |

Of course they made it understeer out of the box. You dont want everyone crashing it because after 7 generations of front engine you suddenly put people who dont know how to deal with mid engine oversteer in that car.
Back when my store had a Lotus franchise I swear we did more body work on them then we did maintenance and repair, lots of people would spin them out during a mid corner throttle lift. |

yes of course, but when the car is being reviewed at the track, i wonder if they kept the street camber setting. The reviews i've read... i think the road and track Cammisa review? wrote of understeer at the track, sort of complaining about it. I wonder if was simply a matter of not having the track front -3deg camber settings.

Yep a pre 2019 SS 1LE and yep, looks like T16. A buddy sent me some pix (he was there doing TT).
Sadly, the car looks done. The driver "claimed brakes" according to my buddy. Haven't driven the circuit (yet), but from what i understand (from folks i know and Randy Pobst), dropping a wheel on exit there always ends badly. That's all i know. PS Sorry no pix, as i wish to respect privacy. |

With all due respect, lets not have this thread become one where we just report on the latest track incident involving a Camaro. Claiming brakes can mean a lot of things... Lets get all the facts, first, before we start to think "another one". |
