Z/28 Is Nothing Without Trofeo R Tires! (SARCASM)

[serpent]

I read they put these tires on the ZL1 long before the z28 was going to be in the works (probably during the ZL1 testing phase, pre production). The engineers said the tires didnt do as good as it did with the Z28. My guess is the weight of the ZL1, almost 300lbs more than a z28.

That's the test I would like to see. 1LE, ZL1, and Z/28 on the trofeos.

Hopefully no one is foolish enough to think that the ZL1 or 1LE would match the Z/28 performance with just a tire swap, but it would be interesting to compare none the less. The more track comparisons I get the better.

"Don't believe everything you see and hear"! Notice they have never released comparison times? ZL1 on GY and ZL1 on Trofeo's. They never have released any definitive data. Just a quote from an unnamed engineer. So according to your theory, if a heavy guy weighing close to 300 pounds drives the Z/28 on the track, it will negate the weight savings of the Z/28 and the cars will be equal? It would hurt the image of the Z/28's track capabilities. I realize the Z/28 is quicker around the course due to lighter weight and the CC brakes! I still would like to see a actual comparison.

Your theory has issues. The weight of an individual is central whereas the added weight of the engine and differential are at the polar opposite ends. This effects handling very differently.

Some people will never be happy regardless of the efforts of others. Some have asked for a comparison with like tire on the 1LE and they did that. Now that is not good enough. If we constantly live our lives trying to make other people happy or meet their demands...we will end up missing out on our own happiness. If you like the car great. If you think it has holes then don't buy it. Damn.

There you go, they tried it on a ZL1 and it wasnt up to par.

Weight is everything, and we are talking about the performance of a track car and tires. Look at F1, there are no fat asses in that sport. I would be surprised if any of those guys weighed more than 185lb.

That's why I got divorced.

I've always though tires are like shoes. Because I'm in between sizes, I order 7-8 pairs from Zappos but usually only keep one of those -- because of fit issues.

Likewise, there are a huge number of parameters that cause one tire to vary from another. Tread design, rubber compound, belt design, and construction are but a few.

Clearly, the design team chose the Trofeo R because it was the best fit for the Z/28, and they likely chose it early enough in the design process that they could optimize certain suspension parameters around the tire.

Thanks, Zfat, for the post! It confirms, in the strongest possible way, that the Z/28's great track numbers are about the package -- not about the tires.

Exactly, they have to "tune" the car to the tires. They don't say if they did any of that with the swap. Square vs. Staggered!

I agree for the most part, but this test doesn't really confirm much in the strongest possible way. A multi-lap road course evaluation would be a sufficiently strong confirmation of what the true performance delta is, and only after the tires and brakes get up to temperature. Not down-playing the phenomenal job that the Z/28 engineers did at all, just wanting to keep it real. Tires do play a huge role. The ZR1, for example, will lay down a wicked fast lap on it's latest MPSCs, much faster than it was capable of on the previous tires it came with.

Why would heads explode? Anybody who knows cars and automotive engineering knows a vehicle is more than the sum of its parts. The Z was engineered as a package; likewise the Camaro with the 1LE option. The components were designed to work optimally with each other. Changing parts around will always monkey with the outcomes and balance engineered into the car.

So you're one of those who takes the easy way out of things? Marriage has always been about trying to make the other person happy, not yourself. If you went into marriage thinking it was supposed to be a 50/50 situation, it's no wonder yours failed. Strong marriages are 60/40 relationships with BOTH individual seeking to make the other happy sixty percent of the time.

Sorry about the derail, but divorce should never be something a person should brag about. Hopefully kids were not in the equation.
