“According to Street Legal Performance (SLP) in Tom’s River, New Jersey, this supercharged 575-hp LS3 V8 for the 2010 Camaro SS not only makes the feds happy but also carries a 3-year/36,000-mile warranty covering all the company-installed modifications, and everything else on the car remains covered by a GM warranty. To maintain those warranties, you must order the ZL575 package through any Chevrolet dealer in the U.S. and Canada at the time you purchase a new Camaro SS. Orders outside the dealership network and installed by any outfit other than SLP carry a lesser warranty.
