Was wondering what fuel is legal for my ITS 240Z? I gave up on making my 280 SCCA legal and purchased a 240 ITS car. Was told by previous owner mix 3 parts 100 octane, 2 parts 91 octane. He didn't state if the 100 octane was aircraft of race fuel. Another question on roll bar padding, are they enforcing SFI padding or not. All my hours of research in the GCR and Fastrack still show recommended. Looking forard to meeting the SeDiv group in June.
