These are reasons the Z/28 is faster than the ZL1.... so yeah it's pertinent.

The OP mentioned nothing about comparing them, just stating a fact. Nothing with "what ifs".

“We used the very best components in the industry to deliver uncompromised performance, lap after lap,” said Mark Stielow, Camaro Z/28 engineering manager. “We made nearly 200 changes to improve the track performance, which cumulatively make the Z/28 capable of 1.05 g in cornering. For perspective, with all other things, equal increasing maximum grip from 1 to 1.05 g can cut up to four seconds per lap.”

The Camaro Z/28 is the one of the first production cars fitted with race-proven, spool-valve dampers. Compared to a conventional damper that offers only two-way tuning for bump and rebound, a spool-valve damper allows four-way adjustment to precisely tune both bump and rebound settings for high-speed and low-speed wheel motions. The wider tuning range allowed engineers to dramatically increase the damper stiffness on the Camaro Z/28 without a significant change in ride quality. Additional chassis changes include stiffer string rates and suspension bushings for improved cornering response.
The very best components in the world are of no use if that component enabled heavy ass car cannot stick to the road. Both the z28 and the zl1 share this problem of physics. The issue is that gm fixed the traction issue on only one of them, and then announced that one is faster. Hmmm. Again this tread is about that 3 second difference, and as you posted about above, a 0.05 g difference cuts up to four seconds. Have you ever raced with race slick versus street tires, I have and slicks make street tires feel wet all around the track. You just helped my argument with the 1.05 fact. Thank you. Come on GM, put a set of trofeos on a 2013 zl1 and tell us how it goes.....

Taken out of context, either ignorant or a cheap shot. I said just the tires is all anyone needs changed to put both cars in a fair test of the zl1's 80% from SS change vs the z28's 200 mods

It is explicitly implied. What else is meant by, " one car is faster than the other," it is a comparison.

Eh, no point really made or stuck, but have a good one anyway.

I will admit that was a mistake on my part. I read "just tires" and quit reading.... All of your post's go the same direction so I just assumed. My bad.

I clearly think you are underestimating this car and all that has went into it. ITS NOT JUST TIRES. I could be wrong and you could be right. Time will tell....

Gm design or even aid in engineering these tires. They signed a contract to supply that tire with that car.


The same thing can be said about strapping a blower on a 6.2. It's only a marketing decision, right?

GM engineers called for specific tire specs and the tires they are using met those.

The z28 is the faster track car, I think that's obvious. With the same tires the z28 will still be quicker in the corners and getting out of them, and the rest will be up to how long the straights are for the zl1 to make up time.

In the long run, I don't think they will finalize a Z/28 that "under-performs" the Zl-1, no matter what it takes to accomplish that. In fact, I think they've got their sites set on a lot bigger fish in the track world...
Yes yes, agreed. This is why I am assuming (my opinion only) that the ring times were a flop against the current zl1 and GM is gonna squeeze more out of the car. So I bet we shall get some announcements of new cuts and mods to the car soon.
"505 HP 427, surprise we meant 600hp 427."
Or
"Did we suggest 3700 lbs, we meant 3300, with an aluminum frame, magnesium sub frame, and balsa wood floors and carbon hood roof trunk wheels trunk floor. Lithium battery too. Price is now only 110,000, but it beat the zl1 at the ring by 8 seconds"
Haha, still if they went that far with the mods, that would be awesome for Camaro people everywhere. I say hell.yeah.

That is where I am in large disagreement. Id like to see GM prove this. Either way, someone will soon after the cars release
