I know SA has the quickest street tired and standard ZF in Australia using full weight.BF XR6T on 50% 98/50% E85 and 275/35/18 Nitto Invo's 260 tread wear.Tuned by Bruce Heinrich's I believe.Std turbo with .50 cover.Plazmaman plenum and 4" race box.

A Dash F6 has also run 10.97 at 131.7mph with lazy 60 foot.Same tuner/fuel and turbo but was run on ET Streets.
Results need to show what tire was used imo.
