i think besides that the road was probably had some oil to allow 2 cars to loose severe controlThe GTR was running on extreme dry tyres, BS RE-070.
I have a friend on the Evo-X came with Dunlop Extreme dry tyres too, the Dunlop SP600 which he drives below 80kph in the wet, ask me what wet tyres to use, so told him to use GY Asy, and he loves them, now should be on Michelin PSS....
