Yes that is the dilemma, a Z/28 or a Z51. Doing the math (based on what we know) the 2 seem very close in 0-60, 1/4 mile, G's and braking. The BIG difference is the lower weight of the Z51. I think the Z51 will have a slightly better ring time...and lower price.

I tried to buy online, but that is only in Illinois. I didn't want to be left out so I drove down to the nearest gas station. If I win, What color C7 Z51 do you want?

I don't care. I'll take the lotto leftovers any day and not complain a single bit.

...without reading much here most recently and jumping in to post after watching the video <several times> with much glee, I want to say, I hope they dont price the Z/28 too far out beyond the ZL1....because the marketing and pre-production talk may not ad up to a position where the Z/28 is that much higher in step over the ZL1 that will command the MSRP. I am not trying to knock it <or be a heretic>....I love it...but pictures and stats speak a thousand words..

...oh BTW I wanted to ad that on Monday I sat in a 2014 1LE SS Camaro with Recaro seats, micro fiber.....nice! I am on the svelt <thin> side and I fit nicely. Nice feel and wrap around affect. Now the down side, if one is hefty or on the larger side you won't fit into them. Just sayin.

..dude, then I am afraid you are SOL on these seats bro...unless you get a shoe horn and really strap up tight with a racing harness in the Recaro seat..... . But this ride aint for comfort........its for speed yo....

After reading the changes to the LS7 are the pistons now truly forged? If so this version of the LS7 is very, very stout.

Enjoy. Great job GM.

If you are a weekend warrior you are not going to run stock tires on it. You ARE going to put a helmet on. You are going to put good gas in it. You are going to belt yourself in. You ARE going to compete. If you truly are a competitor. You're not going to run weak tires, etc. GM stripped it down and jacked up the price based on speed based on reduced weight? OK. I get it. Put some good tires on the ZL1 for a decent comp. Fair? Nothing against the new edition either. Just saying lets compare when/can with simple tire equality. Then lets see if the weight reduction, engine, and rotor setup really cleans up the "Legend" or not.

PS: Just a response to above comments.... seems like he is focused on the ZL1. The z28 is still DYNOMITE!

Let's be more complete in our thinking. He mentioned 25 & 50 laps. There's more to it than tires when your going to do 25 or 50 laps.

No it's not fair because that's not how GM built the car.

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.

The ZL1 brakes are quite good and can handle by my guestimate about 10 laps before they begin to fade away if the driver is running hard. The inter-cooler is pretty effective, but at some point on track heat soak will become an issue. In a 25 lap event at the Ring the Z/28 brakes will be the same on lap 3 as they are on lap 25 or 50. Why lap 3? CC brakes love heat. Based on brakes alone the Z/28 would win by a significant margin. All LS motors are furnaces. The LS7 should hold more off the baseline HP longer than the LSA in the ZL1.

Add CC brakes and 305 rubber to the ZL1 and the ZL1 gets faster. More from the tires than the brakes. CC brakes on the ZL1 will eliminate brake fade for the longer runs. The ZL1 gains 5 seconds on the Z/28.

Tires. The Z/28 runs Trofeo 305/30/19s. The Z/28 with less nose weight and lighter overall will be easier on tires. The last five laps will be telling. The hotter greasier tires on the ZL1 will slow the ZL1 down. While the ZL1 tires are fading the Z/28 drop off will not be as great. The Z/28 pull away on each of the last five laps for no other reason than tires.

There are other differences. The Z/28 aero creates down force and increases corning speeds. The ZL1 aero is more about preventing lioft than creating down force.

The Z/28 differential is intended for road course work. The ZL1 cast iron diff is tough as nails, but not as good at putting power down in the corners.

Two very competent automobiles. One is a hybrid grand touring / muscle car. The other is a hybrid track / street car. Both are at the top of thier class
