IT cars, spec Miata's and the like just don't belong on the track at the same time as GT cars. Obviously they make their speed in such different ways. I did the same test day last year in my new GT-1 stock car with about 30 spec miatas and various other stuff out there. It was totally useless as a test session. They were in my way and I in theres. Did half of one thirty minute session and parked it and let my more GT experienced partner try it. He agreed. Useless and dangerous.
