19 One concern the folks at HMS Motorsport had in our application was head/neck support in an open roadster with a low-back seat. The Miata, BMW Z3, and so forth all have modern high-back seats. After some discussion, we located this great headrest assembly from Cobraearl's FFR Accessories (http://home.mindspring.com/~egroce/); it simply attaches to the factory rollbar with bolts or hook-and-loop strips. We opted for the hook-and-loop installation for quick cleaning and maintenance. We're still considering something for the passenger side, possibly a slip-in headrest with a custom bracket.
