I saw a red one at Carlisle event - and the engine compartment appears much larger than in a Speedster. I'm guess it is just a longer tail (which would shorly need added steel to support aka CMC butt sag). I tried to find a build manual to see if the pan was shortened like the Speedster but could not find one. The top appears same size so suspect pan is shortened. I recall reading years ago that the kit sold for $15k --- where the CMC Speedster was around $8k --- must be the extra engine grill! Reportedly only about 200 were made. One had a 6 cyl Porsche engine (sold to new owner in Japan) and there was a rotary wankel in one in TX.
