C6 Corvette ZR1 & Z06General info about GM’s Corvette Supercar, LS9 Corvette Technical Info, Performance Upgrades, Suspension Setup for Street or Track
Listen don't want to light up all the know it alls because they read it somewhere. Just giving the weights of my cars because I own all three C6 Z's being questioned. Also weights will definitely vary from one car to another but those weights should not be widely different ie less than 40 to 50 lbs if all liquid capacities are corrected as well as different wheel tire combinations are taken into account. All weights are 1/2 tank of fuel. My 2009 Z06 comes in at 3,180 lbs. My 2010 ZR1 at 3333 lbs. My 2011 Z07 at 3136 lbs. After switching to a B92 hood the Z07 weighed 3120 lbs. Further adding aftermarket flow formed 19 inch front and rear wheels with Toyo R888R tires brought the Z07 weight to 3100 lbs.
Even without the aftermarket wheels and tires I can really feel the quicker turn in and better wheel control with the carbon ceramic brakes. The front rotors weigh 13 lbs each compared to the stock Z rotor of 26 lbs. The difference in the rear is probably a little less but I have not tried to weigh them. The change in unsprung weight and rotational inertia is definitely noticeable. Even though my ZR1 uses the same rotors the added 200 lbs of mostly front end weight greatly minimizes the resulting difference.
Again you can take this information for whatever you want to. I am merely trying to give a concrete example of one set of subject models and weights. There is nothing like being able to drive each example on the same roads on the same day with the same driver on multiple occasions to start to get a feel for the effective impact of different equipment. Also keep in mind different drivers will push these cars differently and maybe come up with a very different set of conclusions. Finally all three cars are excellent yet different. Also none of them offer the scalpel precision of my less than 3,000 lb 2009 track setup Z06 with coil overs, carbon ceramic brakes, Katech modded engine, etc however all three are kinder in usage.
The z06 is the lightesf, but it's not that simple, unsprung weight is way more important than sprung weight. When I switched to monoblock forged wheels from my ridiculously heavy chrome zr1 wheels it was the biggest difference ever, since then I bought 9 pound seats and aluminum rails, the car feels totally different
Just curious......and this is a sincere question......is the answer going to be the game-changer to decide which of the 3 to purchase??? There are many variables that come into play that are pro/con for each of the listed models......

no, I’m only interested in a Zr1. That said, in my searching I can’t figure out how carbon owners say their car weighs less than a z06. Then where is the extra 300 pounds on the Zr1 from?

2011 Carbon owner here, 3180 with 1/4 tank of gas. I had a c5z06 with headers and x-pipe and weighed 3050 with 1/4 tank.
Mods that are lighter than stock:
longtube headers
catted x-pipe.
Not sure on tire rim weights compared to stock since I had on forgestar cf10 with continental extreme contact sports.
Weighed my 09 C6Z at the strip a couple months back. Still had 1/4 - 1/2 tank fuel, backpack of camera gear, weather tech floor mats, random stuff in the trunk cubby hole, etc. Car came out at 3130

Hope this info is useful to someone
so stock z07/stock Zr1 is 197 pounds difference. The ls9 weighs 77 pounds more than the ls7 per Google, so where is the other 120 pounds at if the z07 and Zr1 are the same except the engine?

Depends on the trim model, he didn't state what each model was, I'm not sure about the z07, but the zr1 has a heavy duty diff, I believe the axles are also stronger, so not just the huge blower and accessories that make it heavier
And if you're not a professional driver then you're definitely not gonna take advantage of the hp and tq of the zr1, you'd drive the z07 better
Seats and lightweight wheels are the best mods you'll ever do when you buy anyone of the corvettes you're thinking about

Heat exchanger, pump, tank, and fluid. I'd be surprised if the blower, snout, lid, bricks, etc are only 77lbs, but maybe. That blower is heavy when you are trying to put it on by yourself lol.
My 07 2lz Z06 was 3140 with half a tank, fixed back seat on aluminum rails on the drivers side, headers and a harness bar & harnesses when I had it corner weighted.

still waiting on passagemaker to explain where the weight went on the z07.

seems like passagemaker owns all 3, has personally weighed them and has a 4th vette he tracks. So I’d would guess he has some knowledge of the cars, or at least his own. Yet you keep bringing up google as if it is a fact; against real life experience.
what are you trying to prove? Or get out of this convo?

what causes the z07 to be so much lighter when it’s the same car as the Zr1 minus engine which is about 80 pounds more. Trying to understand where the other weight is and passage seems to be the most knowledgeable.

Weight difference between z06,z07,zr1
