I know the 289 knowledge base is not as deep around here, but I was wondering if anyone may know the proper rollbar angle on an FIA car. The 427 is 75degrees, but due to obstructions, the 289 seems like it would need to be 76.5 or more... providing the two are the same distance in relation to the cowl hoop.I think Kirkham cars go with 75, but their framework is modified a bit.

Feedback greatly appreciated!!

Thank you,
Mike.
