I tried all three cars. The Porsche just seems unstable and ready to swap ends at the lightest sneeze. The Lotus felt more stable than the Porsche but was...meh. I got into the KTM and loved being able to toss it around the track. I think quicker times can be wrung out of it with practice and a bit of getting used to the car. I also think that it will be the car that will be best for an extended run.
