SS - available as an upgrade to the Z28 model starting in late-1995 (as a 1996 model). The package include a functional ram air hood scoop and reworked exhaust manifolds resulting in 305 HP and 335 ft-lbs of torque. An optional freer flowing exhaust system brings HP to 315 and torque to 342 ft-lbs. In 1998 with the introduction of the LS1 engine, power was boosted to 320HP, and with the optional SLP exhaust power was boosted to 327HP. The stock wheels and tires are replaced with 5-spoke 17" ZR-1 style wheels with 275/40ZR/17 tires. Hurst shifter and Torsen differential were available options. Bilstein shocks, stiffer rate springs/bushings, and a larger front sway bar make up the optional Level-II suspension. The stock spoiler is replaced with sleeker looking one. "SS" badges replace the "Z28" badges on the front fenders and rear passenger bumper. All cars were shipped as stock Z28s to Street Legal Performance (SLP) Engineering where the above modifications were made through 1997. After that, GM made the modifications on its own assembly line.
