I used Kirkey in our racing sprint car and they donated the41 series Pro-Street Drag for our 2-seat, street legal sprint car. I wanted this style because the large rib protectors would be a tight fit for passengers, being a hassle. Not all people are thin around the hips. lol
This type has what I call wings, so they still keep your butt planted, but more comfortable.
