Hopefully not on your IT motor as that would be illegal. Phasing camshafts is illegal, as offset keys are only to be used to bring you back to stock timing.

not a bad idea though.. I have heard of some people doing just this (not in IT or SCCA for that matter) to dial back the compression numbers.
