If the introduction of the ZR1 into the Corvette lineup has made the base model look a bit dull, the Grand Sport package more than fills the aesthetic gap between the models. The Grand Sport package includes Stingray-like gills aft of the front wheels, unique rims and Z06 brakes. Unique suspension tuning reportedly nets a 0-60 time that goes from 4.2 seconds on the base coupe to 4.0 seconds in its updated configuration.
Corvette Blogger is reporting what it says is official Grand Sport package pricing, and the bottom line isn't as tough to swallow as some may have envisioned. The Bowtie fanboy site lists Grand Sport pricing at $55,720 for the coupe and $59,530 for the convertible. That's a not-inconsequential $6,205 bump for the coupe and $5,360 for the droptop. The Grand Sport package essentially obviates the need for the $1,695 Z51 package, however, so you're basically looking at $3,500-$4,500 for the retuned suspension, widebody stance, Z06 brakes, improved 0-60 mph times, and aeshetic and exclusivity benefits, which doesn't strike us as a bad deal.
