My car is 135" wheelbase, all new tubing, and in order to give the front hoop a period layback, I had Brian add 4" behind the rear axle- which is what is putting my legs in the position they are with the seat pan flush against the chassis uprights. Over the weekend I replaced the tube under the seat pan with flat bar stock, flush with the bottom frame rail and cut the bottom of the seat out, since the pan protruded lower than the frame rail.
There is plenty of headroom, so the seat pan will end up being about 2" higher, and then I'll move the bottom of the seat 4" forward to put my legs in the correct position. With my car, I still think having the shoulder hoop farther back, gives my torso the extra room and getting in and out should still be pretty easy. I can "hook" the back of my arms on the front of the cage and lift myself out enough to just put my feet on the axle to get out. Granted, I haven't done this with a full suit on yet (I don't have one) so we'll see as I go. I'll post a cockpit shot once I get it sorted, but here's a couple shots of the car itself under construction.
