The C7 Grand Sport gave you the Z06's wide body and track-ready chassis with a naturally aspirated LT1 up front, and this one takes that recipe a whole lot further. An A&A centrifugal supercharger now sits on top, backed by a custom cam and tune, a DSX flex fuel kit, methanol injection, an MSD Atomic intake, and an AWE exhaust, while Airtekk air struts with 33-way adjustable damping and satin black APEX forged wheels sort out the chassis. The ZR1 conversion front end, double-sided carbon fiber vented hood, and ZTK-style rear wing make it look every bit as serious as it is. That's more than $31,000 in parts before anyone picks up a wrench, and installing it all means pulling the front of the engine for the cam, mounting the supercharger and intercooler, plumbing the fuel and methanol systems, swapping in the air suspension, fitting the body panels, and dialing in the tune. Every hour of that shop time is already done, so you get a finished build on a well-optioned Grand Sport 2LT and the labor bill is one you'll never see.
