seen the ariel atom and liked it. as for size of the frame i have planned for it to be 9 to 10 feet long and as wide as a crx so i can use the same cv axles and hubs. height i would like to have about 3 to 5 inches of clerance. i think it will hug the ground. weight with a d series i think it will weigh about 1000 to 1200 with me in it.
