A lot of how you fit depends on whether you are long of leg, long of torso or average for your height. At 5'9"/160 I fit either. When I got in Dave Smith's Coupe with Kirkeys flat on the floor I found a surplus of leg room and had a clear view through the windshield. My buddy Aaron who is 6'1/200 with average leg to torso proportions found that although he had more leg room than in his roadster he had to duck down to get a clear view out the front due to the short windshield and front tube of the cage. As has been said, you really need to try them on and keep in mind that different configurations can help improve some areas (but may also hurt in others).

Good luck,
Jeff
