I bought my NSX with these seats already installed and it felt loose to me. Also, I have no intention to track the car so i ended up buying factory NSX leather seats to replace these Forza Sports. According to the product description, they fit up to 38 inch waist.
Taking our ever-popular Forza seat to the next level, Corbeau is excited to announce the Forza Sport racing seat, which is an FIA approved version of the Forza. The Forza Sport is hands down the most affordable FIA approved racing seat money can buy. For years this seat has been a favorite in the European racing scene and we are pleased to now make it available in North America. The Forza Sport is bottom and side mount capable and features energy absorbing foam and 3,4,5, and 6-point harness capability. As a rule of thumb, the Forza Sport racing seat will fit up to 38 waist. The Forza Sport is available in cloth or vinyl materials. Weight 26 lbs. Colors: Black Cloth, Black Vinyl, Black/BlueCloth, Black/Red Cloth, Black/Grey Cloth."[/FONT]
