Technically SLP owned the “SS” badge on the camaro until 2000, when GM bought the marketing rights for the SS from SLP. Up until then all camaro SS’s went to SLP. After 2000, unless specific SLP options were ordered it went straight from GM to the customer. the Firehawk is a specific package marketed and sold by SLP. The WS6 package was the GM “equiviant”, although the firehawk clamed 15 hp over the WS6, the firhawk also had much better handling charactoristics.
The Firehawk was also availible in a Formula package version.
