In 1986, SLP Performance Products was founded by Ed Hamburger. Their mission was to offer the owners of late model Firebird's and Camaro's with a total selection of “Street Legal Performance” products that would increase the handling, fuel economy and all around performance of their cars.
In 1988, the first "Emission Legal" performance package for the new Camaro/Firebird was introduced to the Performance Parts Industry’s by SLP, that began their alliance with GM’s division of Performance Parts, allowing car enthusiasts to obtain SLP's products from their local GM dealer anywhere in the country.
Then in 1991,GM granted SLP's petition for their very first speciality vehicle program, which was the 1992 Firebird-based Firehawk. All the 1992 Firebird Firehawks were manufactured in SLP's own facility, in Toms River, and transfered to Pontiac dealers all over the country.
Chevrolet then gave an approval, in regard to the 4th Gen Camaro Z28, for SLP's Ship-Through speciality vehicle program. Chevy also approved SLP the use one of the most exalted names in the history of Chevrolet, the Camaro SS. SLP then announced their first Camaro SS to the automotive world, in 1996, and were given rave reviews for the Camaro's amazing handling and performance as well as its appearance.
The following eight years, SLP manufactured over 55,000 GM speciality vehicles, such as the Camaro SS and RS models, as well as the Firebird-based Firehawk, WS-6 and Comp T/A models, from their 140,000 sq ft. assembly facility in Montreal, for General Motors and its Pontiac an Chevrolet dealers. Then in 2002, General Motors stopped production of SLP's Camaro SS and Firehawk programs as well as the 4th generation Firebird/Camaro.
SLP then concentrated on growing their Aftermarket and Direct-to-Dealer products, which resulted into their line of handling and performance, along with appearance products, for late-model Detroit- built Muscle Cars like the Mustang, Challenger and Charger, and Camaro as well as Full-Sized GM Trucks and SUVs.
Late in 2007, SLP was found out that the 5th generation Chevrolet Camaro would be going back into production for the 2010 model, but not also was informed that no replacement was planned for the Firebird. Since Firebird was no longer going to be available, and given our intention of producing speciality vehicles for both Chevrolet and Pontiac dealers, it was obvious that the new 2008 Pontiac G8 GT was the only vehicle in Pontiac’s product line-up that made any sense to replace the Firebird. Since the G8 was manufactured off an identical vehicle foundation as the new Camaro, any work done on the G8's Suspension and Powertrain to improve it, would then used on the new Camaro also.
Then SLP, early in 2008, started making all their products that, in the course of time, made up the G8-based Firehawk supercharged vehicle package, which proceeded to the first Firehawk preproduction prototype being completed in November 2008. Following thorough CARB certification and testing, the car was delivered in early January of 2009, to Anne Arbor, Michigan, where Car & Driver magazine concluded their road testing. Then Motor Week TV featured a show on the Speed Channel based on the Firehawk, which aired inn early 2009.
In Late 2009, production of the G8-based Firehawk Drop-Ship Program began. After just 34 cars were produced though, General Motors in formed SLP that they wouldn't be continuing the production of the G8 in 2010, and were terminating the Pontiac brand also.
At that point all the product development, Suspension, Powertrain and Body component engineering for their upcoming 5th Generation Supercharged Camaro Drop-Ship Program was already complete, so SLP promptly turned their attention on start-of-production in October of 2009, and continues in their facilities in Toms River, NJ and Troy, MI, to this day.
The start of January 2012, marked SLP's production of their 525HP Supercharged Escalade Sport Edition and 610HP Supercharged ZL610 Corvette Drop-Ship Programs. In June of 2012, SLP began production of their 2013 supercharged Sport Edition GM Truck and SUV Drop-Ship Programs.
