[Got the Bug]

I have the stock SPF seat with no rails, bolted to the floor as far back as it will go. Tim sat in my SPF last week and he'd have to notch out the dash to fit. I'm 6' 2" and fit comfortably with just enough clearance between my knee and the dash to fit.

Tim - You should also try sitting in Dave Brown's car sometime. I think your best option for an ERA or an SPF is going to be a short racing shell and have it upholstered with a very small amount of padding.

BTW - I also went with the leather steering wheel, which I like and gives me a little more room.
