The lower lumbar support design of the Mustang seat is why I bought it and sold my custom seat. It supports very well and I don't need a backrest which I didn't want to add.
I'd be curious what your passengers think? I like the Mustang lumbar support, but this seat has to work for my passenger.
Thanks, .J
