Mike H,
There is a padded sternum strap, you can see it in the picture if you look real close. Look at the latching mechanism in the drivers seat and you should be able to see the pad.
The shoulder straps aren't "Y'd", they are two single straps going through the same bulkhead opening and attaching to one single point on a frame member. I don't know about the model name, the brand is TeamTech. I special ordered them through a local shop here in Ft. Worth so the straps would be made to length based on my measurements.
I am very pleased with the harness and there isn't anything I would change. Beside the design I liked these because I could custom order the colors to match my car. The yellow on the straps matches the yellow stripe across the nose of my car.
