i bought a hans device

[geeeman]

i recently bought a Schroth 20 degre sport 2

but i find that the Back of my helmet pushes on the hans, and so causes the 2 arms to lift off my chest (even with harness)

my seating position isnt very reclined, so i presume a large angle like 30 dgree hans , would make this situation even worse?

i put some extra pads under the arms which helps abit but they stil dont contact my chest well when helmet is in place and looking up so i can see the road!

anyone experienced this?
