The EB II Falcon SS in late '92 was devised, like the VP Commodore SS V6 it competed with, technically as a production model. Neither were ever intended to be mainstream. Only fans of Group E production car racing would have heard of them.
The Falcon SS' 4.0 six was effectively a prototype for the original S-XR6, lacking only the split exhaust, and with a milder suspension tune. A camber kit and a V8-derived gearbox improved performance and handling, while ABS, an LSD and a raised rear deck wing were also fitted.
Price was $31,467 - $561 more than the superior S-XR6, which deliberately ensured the lack of popularity, not to mention availability issues.
This information is from the October '92 issue of Wheels, though someone on the #eafalcon IRC channel recently contradicted this by claiming the the SS had a supercharger.
