Has anybody had any experience with these seats? I think they are new seat just offered by Sparco and they are fairly affordable...

Yes, I have these seats. I don't recommend you get them unless you are over 6 feet tall.

If you look closely at the picture of the seats, you can see that the lateral supports for the torso are elevated by about 2 - 3 inches. This causes them to ride up under your armpits. I am average height (5'8"), and I weigh about 170. At first, I didn't even notice the design flaw. After some time however, I noticed that my back would be very sore after long trips. That's when I noticed that the lateral supports were riding too high up (close to my armpits) and causing the discomfort.

Also, the semi-circular lateral supports that are suppost to support your sholders during lateral movement are positioned up near my head, thus providing zero support for any part of my body and serving zero functional purpose.

Personally, I think it's a design flaw. I'm waiting to hear back from Sparco about this. I hope they agree, because I didn't see anything in the product description that says the seat is designed for tall people.
