I know, the live-axle/IRS rear the new Camaro's gonna have is not new news...

But it's been puzzling me lately. People have said the new Camaro will have a live axle A) That's what's already in the Holden/Zeta light platform the car's gonna be built on, and B) GM can't build a solid axle any more.

Reason A makes perfect sense, to keep costs down, that will hopefully keep stick prices down.

Reason B throws me for a loop though. All of GM's full size trucks have solid axle rears, from the 1/2 all the way up to 1 ton models. just like back int he old days, when the cars and trucks shared the same basic center section for a rear end, why can't GM just do the reverse today? Take the center section from the 8.6" 10-bolt truck rear, put shorter axle tubes and change the rear brake size, place the spring and sway bar moutns int he right places, and blammo! You have a solid axle for the Camaro. An axle tube is nothing more than tube steel, and with the stock wheel size probably in the 17" range for the base Camaro, the same brakes the truck uses would probably fit the car, and provide great stopping power in the rear.

I just wonder why this isn't an option that's been mentioned?
