Hi all, I am looking to buy a Hans device & helmet with posts for track days and have an adapter plate for fitting moving the belts closer together than stock. My questions are: How does moving the belts closer together works with everyday road use? Does it have any affect whe you aren't wearing the hans device? In order for the Hans device to be effective with Tillet Seats will I need to fit a head restraint kit? How do people get on with these in everyday use? What Hans device do people recommend and what angle for a Caterham, speaking with people at the Autosport show, it was suggested a 20 degree device? Is there anything else I should consider?Thanks in advance. Gregs79
