These are the Ultrashield VS Halo series full containment racing seats used in circle track racing.(I think they are 2013/2014 year model) Originally purchased for a project that is no longer coming to fruition.
One is a 17", the other is an 18". Asking $350 each. (new seats, w/o covers, retail around $475)
Neither has covers as the plan was to purchase from Ultrashield when the project was finished. (If you've never dealt with the guys at Ultrashield in Tyler, they are fantastic to deal with and can make covers for these at anytime.)
The seats are completely new and never installed. They have simply been sitting in the shop.
Shipping can be arranged or possibly meet in the North Dallas, Texas area.
Feel free to ask any questions. More pictures available.
