This says it all, "The formula calls for a spec chassis"....... so yeah, call it what you will, it's just Nascar by another name, paint the Ford grill on to be a Ford, a Holden grill for a Holden, and so on......
I just wish the entire V8SC thing would just crawl up and die and that somehow "Group A" style could be re-introduced. Not gonna happen, but I'm allowed to dream.
