The story about McClaren's car being sponsored by Firestone and Mile's car being sponsored by Goodyear (Shelby was the Goodyear west United States distributor (and where he really made money)) is also interesting. The Firestones didn't last and McClaren demanded a shift to Goodyears - and finished the raise on them. They kept that pretty quiet. I still have an old McClaren driving suit patch (with the kiwi).
