I think I read in a BMR build thread that it was 30-40 lbs total.

Didn't Reuss say in an interview that they would not make any Camaro a 2 seater since they already have the Vette?

The rear seat in the Z/28 is a light weight version. It has no real frame and no folding mechanism. I think it is suppose to save 9 pounds. From the Car and Driver story on the Z/28...

I think it was said that the back seat frame was 29 lbs.

SAE power ratings are voluntary and not mandatory, not all cars have a SAE rating on the new system (hence BMW power ratings disparity).

I thought it was interesting to see the excitement and enthusiasm both Mark Reuss and Al O have demonstrated with this car. You can tell they're busting a gut trying to keep from letting the cat out of the bag on what this car can do, but they still can't resist dropping hints. It must be that good.

When Mark Stielow talks about over 200 changes, and they've only really spoken publicly of less than 20... you have to wonder what all he's actually done. This is going to be REAL good lol.

I'm ready to see some final numbers. No more speculation.

Both of my Z06's came from the factory with 18x10 front and 19x12 rears.

but if you give it time, it might sink in.
That's just it....the Trofeo's on the Z28 are NOT a mod,they are standard equipment. Same as the GY's are on the ZL-1. GM isn't interested in the least in what their cars can do with other than OEM supplied rubber.

I mean mod by part of the changes they made from a ZL1 or other Camaro.

Sure, the ZL1 will still pull harder, but its not going to be as substantial a difference as it is between the GT500 and the ZL1.

Are you all forgetting that the Z28 will be more like 160 lbs down on a GT 500...not 80 HP. Mustang 663 Z28 505 and they would weigh about the same @3700 - 3800 lbs.

Trofeo tires vs Cup tires on the Z06 would be about a wash. The Z28 might be a close match to the base C7 Vette, but not close to a cup tired Z06. The Z06 has a top speed just shy of 200 and I don't think the Z28 could match even a C6's top speed of 183...gear ratio and drag being the killers. I think the Z28 might beat the ZL1's Nurburgring lap times by a few seconds and it will probably be close to the non-cup tired Z06...we'll see.

Logic tells me that the same engine and lesser weight, lower CD, the Vette should be the winner. I agree, the Z28 should be around 3750 lb for weight. My 2012, 1SS Camaro weighed 3820 and the weight savings on the Z28 should reduce that weight by at least 50 lbs. I'm guessing 3750 on weight.

No matter what, the Z28 is going to be an awesome performer. I'm hoping the price isn't going to be sky high so more of us could afford one.

I double-checked and according to car and driver's buyers guide for the 2013 Z06 the fronts are 18 x 9.5 and the rears are 19 x 12 so you are correct on the rear wheels.

http://buyersguide.caranddriver.com/...ette-z06/specs

The better balance of 11" in the front and rear will give the Z/28 less understeer and a more balanced cornering stance. However the curb weight of the Z06 at 3175 lbs is something to contend with. It will definitely be faster in the straights.
