I've been saying recently that the old Simtek mod was too fast for the S397 DLC cars, but I have to apologize and retract that statement. The Simtek cars are much slower. I had un-installed the Simtek mod once the S397carpaks came out so I lost touch with the mod. I seem to remember the URD GTE cars were not matching up with the Simtek GT3 so I guess I carried that memory with me without checking. Anyhow, as far as merging the Lambo and Ferrari into the S397 carsets, that gap is actually larger than I expected, but slower. The default Lambo setup felt like air was packing under the nose, high speed corners would result in a light feeling via the FFB and reduced cornering. My first impression was similar to the S397 Mercedes, but I quickly realized the reduced grip went along with the light FFB on faster corners. Top speed at Sebring was 8 to10 kph lower than the S397 products I've driven lately. With rf1/gtr2, it was fairly simple to check AI performance as the hud was displayed when using the swingman camera, But I'm not aware of that option in rF2. I'm not sure how much time could be recovered with forcing AI setups. Maybe it's time we ran a full testing program to find the strengths and weaknesses of each mod.
