GM Stocker rear end

[njk53]

I think the point of this whole discussion is the factory cars are allowed to use rear ends, springs, and overall designs that are nowhere near the OEM configuration. In the old days it would have been classified as a modified production car. I just read the aftermarket has has available OEM type rear ends that are capable of withstanding 1,000+ horsepower for the Challengers. The factory cars should be running OEM design rear ends like the rest of us. Then there is the argument the Corvettes were allowed to eliminate the IRS yes but, they had to run a GM rear end. Also, in those days, the aftermarket wasn't making durable IRS components to take the punishment because of low demand, but it is a different story today.
