Corvette Performance
C5 | Z06 | C6 | ZR1 | C7

Is there any truth in the C5 drivetrain robbing power?

That more than makes up for 10 or 11 rwhp.
I've always used 15% manual and 20% auto for a solid axle car...

It's not that much difference. A basic f-body with minimal options like my 98 Formula was just under 3400 lbs. My C5 is just over 3200 lbs.

I've seen WS6's and Trans Ams weigh in at 3600 to 3800 lbs! And my Z06 is only 3100 lbs! And if 200 lbs isn't much extra weight on a sports car, then why did Chevy go through so much trouble to loose 100 lbs on the Z06?

Shipping weight is 3045 lbs. on a Z06, Coup is 3182 lbs., and a Convertible is 3195 lbs. Give or take a few pounds for options, trans , and gas in the tank when shipped. They didn't go through a lot of trouble. They already had the hard top body that was not selling real well. It was a little stiffer chassis body combo that the coup so they used the hard top for the Z06. It is basicly 150 lbs lighter than a coup. That equalls about .15 in 1/4 mile times.

You are saying that they didn't go through a lot of trouble because they used the fixed roof coupe as a platform? They obviously went through some weight reduction for the fixed roof coupe didn't they?
Why doesn't the Z06 have a removable top, telescoping steering column, 12 disc changer, sport seats with electric bolster and lumber adjustment, no rear cargo covers, and why does it have a thinner front windshield and external antennae, lighter rims and less sound dampening? TO SAVE WEIGHT. They did a lot of things to save weight, which you seem to think is some insignificant engineering feat! Think again, I work in Engineering and all of those design changes combined required a lot of effort and man hours.
In addition to that they modified the suspension (shocks, springs, sway bars), drivetrain (more hp, better clutch, and different transmission gearing), tires (wider front and rear, super car compound )and added cooling ducts to the rear brakes. So there is a big difference between it and a standard coupe.

I was reading an article on the comparions between the coupe and the z06, (I believe it was MotorTrend - I'll have to ask Vince), and they said with just swapping the stock coupe wheels with the z06 wheels, the handling increased to almost z06 levels, showing how much a difference the wheels alone make.

Yes, there are some differences most of the weight is just not adding things that weigh something seat with electric motor and power antenna same. Base seats were already in the base vettes. Not a big investment in time and energy in the car. Most was in the engine. Shock and pring and say bars. They really didn't have it right that was why there was a 20 hp jump the next year. I think we are agreeing to disagree have a nice day sir.

I believe it Vince, I am doing the same thing. I'll weight mine also.

I could feel the difference just picking up the boxes.

Does anyone know if HRE's compare favorably in terms of weight?
