[FireSale]

The Kirky back brace is a different animal. It's a horizontal flat aluminum plate formed to the back of the seat that bolts to the cross bar of the cage/rollbar. Adds lateral strength and twist resistance to the seat.

As Mike said, it's a unit. Cage/bar, driver restraint, seat and bracket, helmet, steering and brakes. Take care of them all and be safe.

Oh - and think straight, too...
