I had the car on the track for the first at Pueblo a few weeks ago for a test day. In turns 1, 5 and 6, in particular, I really liked how the leg extension held me in place. No bracing, no tensing up. The extensions were all a good addition to the car (to say nothing of the protection they afford).

Do you have a picture of the seat in the car?

Here is an (old) picture of the seat in the car without the fabric covers on. I do not own the car anymore, but the seat is for sale by the new car owner in the advertising forum.

I'm a bit confused.

Butlerbuild's website says: "Our SPEC RACER FORD Seat is available from SCCA only. Seat can be converted to full containment by adding a Sportsman Advantage Bolt-on Head and Shoulder Kit."

This kit is shown in the attachment. It is a much bigger component. The pictured items seem to be the individual items, and that is all that is shown in the SCCA parts list.



A more significant, frame-mounted Butlerbuilt head restraint available?

The Butler restraint shown above is available, i have one on order with CSR.

When I did my seat in 2013/2014, the parts shown is what they were selling. There is more (and better) options available now for the head restraint.

in the picture from davep, I see three squares cut in bottom, the one in the center I recognize as the sub strap hole, what are the other two?

Sorry for the long delay. Just saw this question.

The single hole was for a 5 point harness. The two back holes were cut to convert the seat to a six point harness with two sub-straps.

Finally got around to doing a write up on installing the ButlerBuilt Seat in the car, hopefully this help other racers. It shows a few of the features referenced in this thread including the 6 point mounts, step for HANS device and others.

There can be an issue with a Butler seat with tall people. We had to remove a Butler because it did not pass tech. The driver sat up high and did not meet the roll bar to helmet clearance. We recommend sitting in a car with a Butler and make a measurement before you buy one and have to take it out. If you don't fit in the standard fiberglass seat you might want to consider a bead seat.

The second roll over structure must not be less than 50cm behind the first. It must be high enough
for a line extending from the top of the front structure to the top of the rear structure to pass
over the driver’s helmet when he is seated normally in the car with his helmet on and the seat belt
fastened. This second structure behind the seat must be symmetrical about the lengthwise centerline of the car and comply with the following dimensions: The top of the roll bar must be at least
