I remember JusticePete saying something along the lines of with an optimized suspension set up, the sway bars don't need to be as big.

I wonder about that. If and when they release the final Ring time for a dry track, I think they'll want video. So, unless they've been holding back on us and sandbagging (by saying that stitching all their good sectors together should give a 7:31.xx), I have to think they'll return to the Ring in May to run some final, good weather hot laps for posterity...

Speaking of which, I'm surprised that the Z28 is only 55lb lighter then a SS, even taking into consideration its increased mass on certain components for structural rigidity, etc.
Yes Motortrend did get 60-0 in 101ft with a 1LE.

Im looking forward to Motortrend running the Z28 on VIR, we know where the 1LE and ZL1 stands.

so it weighs 3,820.
I thought they said last year it would be a hundred pounds less than the SS.

Hundreds less than the ZL1.

On a race car you tune the suspension with the spring rates and the sway bars are used to fine tune. At some shorter tighter tracks (Waterford Hills in MI) some races discount the sway bars. For the street the OEM have to compromise the best of both worlds which usually means a softer springs with a larger bar (1LE)

The Z/28 is a "no compromise" track car that will be driving on the street.....so stiffer spings combined with the DSSV dampers will be doing the job and smaller sway bars can be used.

Eaton Trutrac and JTekts Torsen diff are of the same design......Both should work the same.

That is a general marketing statement......It depends on the trim and options.

If it does weigh in at 3820 that is withing 3lbs of my 1LE with a 1/4 tank of fuel (1ss/non RS, no sunroof)

Having driven a couple cars with Carbon Ceramic brakes on track (ZR1 / Ferrari) The inital stopping distance when cold is not the greatest result of feel from the them (relatively speaking as it best most) What is impressive is how they get better (short, better bite) when hot and then continue to be consistent lap after lap.

To the last point, anyone not familiar with cold ceramics should be advised not to push the car with cold brakes. You will not enjoy that braking bad moment.

This link claims as much, http://www.motortrend.com/roadtests/...le_first_test/

HOWEVER, I find it hard to believe a 1LE brakes from 60 in 20 ft less than its SS brother. + based on that math the Z/28 should brake under 95 ft, which I'm sorry isn't going to happen. Motortrends fastest braking car they have tested was the 2011 Corvette Z06 Carbon edition which stopped in 93 ft. That car had the same, or close to size ceramic brakes as the Z/28 will have and it weighed a good 600 lbs less. So I do not see a sub 95 ft brake from 60 mph happening.

People need to stop making fun of my gal. Sure, she's big-boned and a little heavy in the rear -- but she knows how to dance…

Because of the brakes and Trofeo Rs, my prediction from 60mph to 0mph is 103 feet.

You forgot to mention tires! The 1LE has a wider patch, and stickier compound out of the box, over its SS bother.

Nose dive and suspension dynamics also play a role in this.

As for the math, it's not a direct proportion in the formula .

Getting back to the brakes - how quickly do you all think they will need to be replaced and how much will a new set of them run?

If you run the wickerbill you will also want the chin spoiler...It will create enough down force in the rear that the front will have lift at speed.

Just look at the prices for the Corvette ZR1 CC brake parts...Front rotors sell for $1700 each online.

It was stated here somewhere that GM says the rotors should last 90,000 miles of street driving. What that translates to with tracking the car I don't know.

Because the Z/28 is intended for the track, air conditioning was deemed non-essential component. The deletion saved 12.9 kilograms <28.4 LBS>. Air conditioning is available as an option.

The weight reduction in practice is going to be much less. Go look at the forum posts from most of the people.

Example: http://www.camaro5.com/forums/showthread.php?t=338803

Of those that have an official placed order most are adding AC and quite a few are adding the Stereo back into the car. The AC is 12.9 kg or 28.4 Lbs. Assume the additional speakers add no weight many Z28 will only have a 26.6 Lbs. weight difference and most likely the difference will be less.

I know the follow opinion will not be popular.... (pulls on fireproof underwear)

This car is cool but really not impressed with the weigh savings. Buy as a collector car but for the $$$ it is not a great value for much anything else.

Track car only I would buy a 1LE... remove the AC... cam/ head work and sticker tires. Much cheaper to enjoy on the track and would be 99.9% Z28 and may be faster. For dual purpose car the ZL1 is much better choice. Add a 2nd set of R Spec tires/rims like the Z28 has and it will be very close on the track (long track this ZL1 may be even faster) and still be a car that makes sense on the street.

Other than bringing back the Z28 name this car is a solution to a problem that did not exist.
