There were two highly tuned Solstice’s at this year’s SEMA auto show that managed to catch our attention. First there’s the Club Sport Z0K, a fun little weekend track car, followed by the GXP-R, perfect for those Sunday drivers who wish they could be down at a track.

The Club Sport Z0K was built to celebrate the Solstice's first-ever Sports Car Club of America (SCCA) Showroom Stock B National Championship and matches the SCCA’s production package complete with a five-speed manual gearbox, limited-slip differential and the stiffened FE3 suspension. Engineers left the 177hp 2.4L Ecotec engine untouched, but have added a full roll-cage, Hoosier racing tires, upgraded brakes and a removable carbon fiber hardtop.

For the GXP-R, modders added a turbocharger, which takes power up to 300hp with 315 lb-ft. of torque, and is countered with a SSBC Performance Brake Package that resides within 19in wheels shod with Goodyear Eagle F1 tires. Visually, the car has been enhanced with new front and rear bumpers, a new grille plus side vents, and is decked out in a bright Hydro Blue.
