Hayden Wheels has just started selling a new neck support system. You can see the Leatt system on our web site Haydenent.com.
The Leatt company has been around for a long time making neck supports for motorcycle racers, but now makes a SFI approved system.
One of the features I like is it has a low back piece, our team's 1'st Hahns was high enough it got caught on the roll cage, also the Leatt has seat harness channels. And it weighs 2 lbs.
Anyway, just call me with any questions, 800-624-3803
