Floyd,

This is from the IHRA rulebook: Stock class

UPHOLSTERY: Must have full factory-type upholstery, including front and rear seats when
so equipped from factory, and factory-type floormats in place. No interior gutting permitted.
It is recommended that driver’s seat tracks be bolted down. Rear seat may be removed
when roll bar or cage is installed. Area must be carpeted. Sun visors optional. Class W may
remove rear seat, provided the area is covered with carpet or approved material.


My understanding on this, you can use just about any factory seats. Racing seats are not allowed. Now, in saying that, I've heard there are cars running in stock that DO have racing seats? I guess it just depends on where you run and how they handle tech.
