SS Performance Package – includes 325-hp 5.7L LS1 V8 with forced air induction system, unique hood air intake, low restriction exhaust system, synthetic engine oil, P275/40ZR17 Goodyear Eagle F1 performance tires (maximum speed rating), 17″ x 9″ 5-spoke aluminum wheels, specially-tuned performance suspension with larger front stabilizer bar, stiffer springs, unique shock valving and stiffer bushings, specific exterior and interior “SS” badging and unique rear deck-lid spoiler

Ram Air Performance and Handling Package – includes specific low restriction dual exhaust system, Ram Air induction system, functional hood scoops, 325 hp, 5.7L LS1 V8, P275/40ZR17 performance tires (maximum speed rating), 17″ high-polished aluminum wheels, specific front and rear suspension with higher front and rear spring rates, unique shock valving, stiffer Panhard bushings and 3.23:1 rear axle ratio with automatic transmission; includes 3.42:1 rear axle with 6-speed manual transmission

The 1998-1999 and some 2000 WS6’s got 1LE springs and other minor 1le parts, different decarbon shocks, ect. Nothing major, but it was more than the simple swaybar upgrades of the mid 2000-2002 cars got.

1998’s also did not get the dual exhaust, instead they got a 3.5″ stainless 1 out the left

**** Just because an ls1 is equiped with the optional “performance” packages does not make them faster ****

• Torque Convertors: How they Work– What size is right for you? depends on the application DO YOUR OWN RESEARCH, start in the Automatic Transmission Forum we have here, its there for a reason . General rule is 3200-3600 for daily drive, 4k+ for alot of track use.

• Manual Transmissions: How they Work– When looking to upgrade think of current and future mods. 01-02 cars come with the ls6 clutch and hydraulics which is a good setup for basic bolt on and daily driving.

  – You’ll find the Spec 3 to be one of the most popular clutch setups here. Ram also makes a nice setup. Again, Do your OWN research n he Manua Transmission forum concerning chatter, clutch break in, hydraulics, ect. 98-00 cars will want to upgrade to the 01+ hydraulics when installing a new clutch.
