Sharp entered the title-deciding weekend just one point ahead of Hitech racer Macintyre, but a lights-to-flag win from pole in the opener, with Macintyre third, put the New Zealander in a good position to take the spoils.
Both drivers safely navigated starting at the back of the reversed-grid middle race but Macintyre only slightly reduced Sharp's lead by finishing seventh to his rival's 11th.
