Helmet hits rollcage

  1. #1
    At the moment i've got peasant spec corbeau forza seats but my helmet hits the rollcage and the part of the sunroof where the runners sit in. To solve this problem i need to drop the seat pretty much so its sitting on the floor. I quite like the look of the sparco pro2000 seat, so because i'll be moving to side mount i'm hoping this will cure the problem?

    I'm about 5' 10"-11" so by no means tall, has anyone else had this problem? Are motorsport helments thinner? I'm currently using a motorbike lid.
