You have to look at this from a business sense. Why would they offer the ZR1 suspension in two other models that cost around $74,755 (Z06) and $50,000 (Z51) and then expect people to continue to pay $30,000 for only 100 extra horsepower or $50,000 for 200 extra horsepower; Something people could easily do themselves for much cheaper, especially with the Z06 by buying an aftermarket supercharger.

You can't modify a suspension as easily as adding a supercharger and modifying the engine output.

Giving all vettes the same suspension would make the ZR1 useless. It would make the ZR1 a little better then a trim upgrade. In other words: Not worth the money.
