Sure there are faster mods, but they just don't seem to have the realism that the aforementioned ones do at least to me. Last but not least is the MAK Porsche 962. S397 has really stepped up the bar on these. Kudos to S397 for the Brabham, March, and McLaren mods, all very realistic and pretty fast. I set the dev version up to be a road racing setup, but for the most part just use the original iDT version. The aero settings on this mod appear to have been adjusted a bit liberally to make it both a road course and oval car. I've played with a development version of Champcars with a few alterations to update the physics and remove the 'dragging pan' effect. There are faster cars, but those I have tried lack the realism in differing regards such as tire behavior, tuning response, and in the case of modern F1 cars, the sounds are off just enough in most to be downright annoying.
