For sure it was quite an accomplishment and an excellent time....even with the wet track and rain....If it wasn't a factor, it would never have been mentioned in the press releases or a quicker time wouldn't have been projected by the guys who ran it....
The idea was to see how quick it went at the ring compared to other makes....Maybe the quicker cars on the list hit some wet conditions as well....But I have my doubts they did.... |

Agreed. The purpose of running the Ring is for comparison. The only way to have an apples to apples comparison is to run on a dry track. I'm 100% certain that all of the other makes do everything they can to ensure they run a dry lap.

Well direct apples to apples would also have to be done at the same time by the same driver. Same track conditions, temperature and humidity play a big part too.

Very true, but its simply not possible to recreate exact track conditions. However, it is possible to use the calendar, weather forecast and weather radar to maximize your chances at a dry lap.

Trofeo information from the Pirelli website.
Designed for racetrack driving on dry asphalt. Developed to provide even greater performance - on the occasion of Track Days - when fitted to the most powerful vehicles such as Porsche, Ferrari, BMW, Lamborghini, including the MY2012. With P Zero™ Trofeo R you can fully appreciate the performance of extreme vehicles in complete safety, especially on the track. In extreme conditions, typical of racetrack driving, it reacts with precision to commands. On dry asphalt, even in the most demanding sessions it ensures high levels of grip and constant trajectories. P Zero™ Trofeo R is not recommended for use in very wet track conditions. Specific for racetrack driving, it is approved for road use, enabling travel to the track. In the event of very wet asphalt, with the risk of aquaplaning, prudent driving at reduced speed is recommended. http://www.pirelli.com/tyre/ww/en/ca..._trofeo_r.html Not stated on the website, just like the GYs on the ZL1 and 1LE, tire grip is reduced by cooler temperatures. They ran on a cool damp then wet track. Adam Dean and the Z/28 put down one hellofa lap. |

I was just saying for a direct apples to apples comparison. Driver ability can also have a big influence.

....But not for the ring. The seat time each driver has with each car as part of the test team is probably off the charts and produces the best results possible. |

Trofeo, Michelin Pilot Sport Cup and Pirelli Corsa System all have minimal tread depth when new (5/32" or 6/32") so there are not large channels to allow the water to escape. Some hard laps and you're down to 2/32". They are actually not bad in the "moist", having predictable break-away qualities, but treacherous in "wet" (easy hydroplaning) and sure as hell suicidal around anything frozen :-)

I think very few of you who are not impressed by the time have never driven on a wet race track. The level of grip on a wet track is almost non-existent. I for one was impressed, and if ya'll would bother to read the press release, GM predicted up to 6 sec a lap faster if all were dry. I think that may have been conservative prediction.
On a side note, I can't believe a Mustang guy has to defend a Camaro to a Camaro site...
