No, strangely enough the 23 is roomier leg wise. I think it is because the 27 is channeled 5 inches and the 23 only 3 inches. Now footroom is another issue. Because the 23 is so low the 350 turbo is sharing a lot of cockpit space with the driver. The floor is almost flat in the 27 so there is room for 3 pedals. The other oddity is that I sit deeper in the 23 than the 27. Not sure if it has to do with that extra 2 inch channel or if the 23 bodies are just deeper.
Over the years I have continually lowered the seat in the 27 because I was sitting so high in the saddle. It was very comfortable up there but people kept telling me they thought I was like 7 feet tall until they saw me out of the car. :eek: I originally had all my switches and even a stereo under the seat but those are gone and this time I will only have a thin bench pad across the cockpit to sit on, about the same thickness as my 23 has.
I might even pick up a couple miles per gallon because of less wind resistance. :p:D
