powerhorse.... my GP4 is absolutly original.... I don´t have the 2003 liveries, coz my PC is to slow to run high detailed graphics (AMD 1200mhz, 64mbram, 16mb Voodo 3D)!!!!
If you want, I can email my carsetup to you, I´m using full wings (20-20), maybe that´s why you felt such a difference on grip!!!!
Oh, and I´m running on soft tyres as well, of course!!!!
I don´t know why you felt such a difference on my grip setup.... it seems pretty much normal to me.... again, my GP4 is absolutly ORIGINAL, no updates att all!!!!
