I think the fastest lap times on almost all GT3 tracks come from a car that can accelerate hard and early from every corner. With the exception of the S turns on SSR5/11 and Midfield, transitional handling and snap oversteer isn't much of an issue.
My cars are a "touch" loose, but not overly so. However, with good corner entry speed, I can power out of all the important turns without pushing off track.
