Thanks Leo, I think it was in AMC where i read the Can-Am rules were changed which prevented the SR4 from racing there. Just another of those what-could-have-been stories. Would have been interesting had he been able to race it there. The L&M F5000 series was lucrative by Australian standards, but the Can-Am was far more lucrative than F5000. The Can-Am was largely credited for establishing McLaren financially, from which it could quickly expand.
