You can't be serious. I'm obviously not speaking from experience, but your trying to say a car that is built by two model airplane builders in their garage, will outrun an exige which was engineered by one of the top suspension tuning manufacturers. The lotus produces 100lbs of downforce@ 100mph. How bout the javan? It may be faster in a straight line but that's about it.
A quote from Vicki Butler-Henderson about the Javan's handling "On the goodwood racetrack the R1 was skittish at the best of times.....instead of feeling well planted and secure, as 100mph came and went the R1 mimicked the mating dance of a frenzied fly, doing a poor job of finding grip".

I'm just saying, "killing" a Exige on track is a lofty goal that I don't think the R1 can achieve.
