Has anybody measured the seat back angle of their bead or speed seat? Asking because I am shorter that my son, my seat back is approx 30 degrees, while his is around 20 degrees. Used the machined pad of gearbox casing as 0 degree ref point.

Is anybody else at 20 degrees, and are you using a 20 degree HANS?

Has anybody successfully modified the bead seat to increase the angle?

Thinking of removing some material ahead of the butt in order to scoot it forward, then make an insert for the seat m behind the drivers back.

Thanks
