I was just looking at Z06 and wondering why fixed roof? My first guess would be power increase, but then when you think about how many C6 owners with modified motors and forced induction. I don't think I have ever heard of someone twisting their car from torque. See my point? Am I missing the big picture? What are the reasons that Z06 has fixed roof?

Stiffer Body and Chassis together equals better consistent handling. That is the simple answer.

Actually the Z06 can (and does) twist the frame from the increased torque. The difference being that the Z06 uses an aluminum version of the C6 frame. The coupe and convertible use a steel frame. The Z06 frame is 136 pounds lighter than the coupe and convertible steel frame. This was done to bring the overall weight down to bring out the performance and improve the pound per horsepower rating of the car.

The Z06 will twist itself up so badly with the roof panel removed under performance driving that the roof panel in some cases cannot be re-installed. This was testing on some prototype cars and the fixed roof panel was the ultimate solution.

The Z06 has an aluminum frame, magnesium engine cradle, titanium roof frame all for weight reduction. Regular C6 is all steel and the weight reflects that.

Aluminum is not as rigid as steel obviously. Z06 needs the fixed roof for rigidity given the added torque and track intended design.

My only gripe about the fixed roof is that I wish GM would have given the car it's "own roof". So that there were no "lines" where the roof would have come off.

Again Talon comes through concise and to the point.

The original desire was for it to be a removable top, when it didn't work out I believe that timing, design effort and cost became a factor. Further, and of equal importance is the issue of the assembly operation. With the current configuration the car can be assembled using all the same mechanization and fixturing that the coupe uses which saves time, money and line speed.

That must be some serious torque to go twisting the car like this? But then again when you consider a top off situation the only part is the floor and hump keeping the car straight.
