Race seats that are height adjustable
 

I've only been able to find race seats that allow you to recline the backs forward and back and slide the whole seat front and back. Havent seen any that have height adjustability. Anyone know of any that exist?

Why would they be height adjustable? A race car is set up for one driver and everything should stay in the same position because it fits. Even a reclining chair is a little bit mad. They may be out there but don't be surprised if you can't find one.
