As much as the somewhat low tech approach of certain Corvette systems do not appeal to me from a technical perspective, you can not argue with results. Bruce is spot on here. The transverse composite leaf spring rear set up on the Vette (Z06 and ZR1) is not your father's pick up truck leaf spring set up. It is light, highly refined and effective. 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.
