I'm not going to lie, I sat there and watched the two Camaros together. What you really see is not that they are going into a turn at different speeds, and not that the ZL1 is putting out higher speeds or better acceleration, because it doesn't look like it is, but what you see is the Z/28 coming out of the corners and much higher speeds in some cases. Tighter the corner, bigger the advantage the Z/28 has. No surprise.

i agree, much lighter car overall far less weight on the nose without lugging around the supercharger, better suspension, better brakes and bigger $$ i'm kinda surprised the z/28 i'snt faster than it is. and of course the vette dominates way lighter, more power and almost double the $$

Makes me wonder what the ZL1 would do around the ring with the same tires as the Z/28.

Thats the key i believe..... Did anyone here all that tire noise coming from the ZL1

They should put the tires and brakes on a ZL1 and run it at Milford, that way it is not as expensive. But I wonder if they don't want to know those results?

I agree completely. They might not want to see that combo on the ZL1 because it might take away some of the glory from the Z28.....

[jessrayo]

When I watch the videos the thing that amazes me is how fast that ZR1 is accelerating. There are a lot of sections the Camaros run flat out where the Corvette driver is lifting because the car is too fast.... On the final straight the corvette driver lifts at the crest of the hill and does not use any downhill for a speed boost, now he is already going 180 up the hill... the Camaro's both get a slight down hill boost at full throttle before backing off for the corners.

I really would like to see what one of those guys could do with my car on that track. I wouldn't mind trying it myself but a track like that is going to take a lot of laps before you really get a feel on how to get the best time.

You guys are all missing the point.

Who cares what tires and brakes you can put on this car and that car. Are the ZL1's brakes inadequate? No. They're better then 99% of ANY car on the road.

Are the tires on the Z28 better? Sure they are...on a TRACK. Have any of you ever driven a car with COLD race spec tires on the street? It can be down right scary..not to mention the tires would wear out very fast.

2x cars built for 2x different purposes.

The ZL1 is the STREET car that can still be used on the track.

The Z28 is the TRACK car that can still be used on the street.

Once you all get and understand the difference, it makes perfect sense.


You can throw Toyo Proxes R888's on a 2010 Cobalt SS/TC and im sure it would be a lot faster then it would with the factory tires it came with...but thats not the point...it didnt come with that.

The ZL1 you all love and enjoy now was supposed to be the Z28...but like Al Openheiser said himself...it didnt deserve the legendary name plate Z28.

You dont have to like it...if you prefer the ZL1, buy the ZL1. The people who want to go really fast on a track and not worry about voiding there warranty by modifying there ZL1's and SS/1LE's to increase the power/braking/handling will gladly scoop this new Z28 up.

With a square tire fitment the ZL1 speed would improve, but it would not equal the Z/28 on a dry track or warm day. At 55 degrees the Trofeo has lost a minimum of 25% grip. Just like the GYs on the ZL1. With any water on the track, the GYs would have an advantage because it has treads to work the water away. On a cool damp, not rained on but not dry like a 72 degree sunny day track the GYs have an advantage. Get to 65 degrees with enough sun to take the chill out of the track and the Trofeos are glued to the track.

The GYs are an excellent street / track tire. When they are run hard on the track they let you know they are working hard. The Trofeo is a great track tire that just happens to be street legal. Made with softer stickier rubber they are much quieter on track.

We are not missing the point, we have enquiring minds. Putting the same wheels and tires and brakes would give a good comparison of the powertrain and aerodynamics.

Based on our experience with the 305 setup we created in 2009 we know that 305s are good for 2.7 seconds at Gingerman. Those are RE-11s and the Trofeo is a street legal slick good for another 2.

Best possible ZL1 Ring time with ideal weather and Trofeos 7:41:47 - 5 seconds = 7:36.47

Best Possible Z/28 Ring time with ideal weather 7:37.4 - 8.5 seconds =7:28.9

55 degree overcast skies with a damp track suck the life out of the Trofeo tires. When I say damp I don't mean rain wet. I mean an over cast track on a cool day never gets as dry as it would on a 65 degree sunny day. Rain wet is much worse. The report from Al O states they already ran a 6 second faster lap without video. Get the same car and driver out under the right conditions and I say the time is low 29s or high 28s.

Time will tell.

[Betiwin]

This^^^^^. Big Al has already said 7:31. That's 10-11 sec less than the ZL1. Yes I'm sure one could pull 3 seconds out of the zl1 time with better brakes and tires but It safe to say the ZL1 is still 8 seconds behind the Z28 on the same day. The Z28 is the track king camaro. The ZL1 is no less bad ass, just more of a grand tourer with all the luxury feature and go fast goddies.
