There were two beautiful FBs on the PRI show floor. A stunningly turned out Sthor and the new RF1000.
One thing that I found interesting was the way the RF1000 handled the flat bottom rule to also achieve a long high arching front nose. You'll see two pictures posted. Even though the new chassis arches up from the flat bottom many inches behind the line that runs across the rear of the two front tires, the bottom continues forward on the same plane until it intercepts that line. So, the result is that one has a "flat bottom" between the rear of the front tires and the front of the rear tires, it's just that in some areas there's nothing above the "bottom" (the small black piece in the pictures). Cool thinking. The RF1000 has been homolagated by the SCCA.
Lots of ways to skin the ol' cat.
