Hi Lowell,
I'm 6'1" and know what you mean about needing cockpit room.
The 2 things that bother me are the edge of the trans tunnel and the fiberglass cover on the door hinge. Here are a few ideas to get more room in a SPF.
The newer SPFs (1300 and up?) have re-designed lower seat pads that make you "sink" farther down in the seat.
If you are to be the only person driving the car you can remove the seat tracks for some added leg room.
I have a Nardi wood steering wheel that looks ten times better than the plywood one that comes with the car. It's main advantage is being 1 inch smaller in diameter which gives you more leg room.
I plan on cutting a wedge out of my trans tunnel where my leg rests (there is room brfore hitting the trans) and glassing in a curved section for clearance. I was thinking of placing a pieceof foam cut to the shape of the tunnel to fill out the carpet so the cut would not be noticable.
Keep your ignition keys to a minimum. I have gouged my knee on the extra keys
The Second Strike newsletter has an ad for a pad that fits on the
door hinge. I don't have one but they look pretty good.
