That being said the GT2 C6.R Vette did go with an upgraded to the leaf spring set up to a full coil over in the rear. From that we can conclude either the performance or adjustability dictated the upgrade. I would guess a bit of both, not just adjustability. So even though we might conclude there is a bit more performance to be had from a more traditional rear suspension set up for the production Vette, you simply can not argue with its handling prowess.
I would postulate that, in this case, performance is
adjustability. I can't see how you could adjust the transverse leaf springs in any meaningful way, so you'd need to have a bunch of those lying around, with various curvatures and spring rates applying to various tracks, and/or conditions.
Given the nature of those springs, the setup would be somewhat complex, and the cost would be fiendish.
Better to have easy, on track adjustability with tried-and-true coilovers.
PS - I'm surprised they don't have coilovers in front, as well. Thought they did.
