Looking for a helmet myself and yours looks good.

 

If you are serious about safety for high-speed track events I also suggest people use a Helmet Support Collar. These ride on top of your neck/shoulder and fit under the bottom of the helmet. Although they do reduce your head movement a slight bit, the only time I have noticed it is when I'm in false grid, as soon as I'm out on track I do not notice it.



I have bought several of these things until I found one I really like. I'm now using HMS's own brand and love it. http://www.hmsmotorsport.com

In a highspeed crash there is a lot of neck movement, and with the weight of the helmet on your head the movement is even greater. The neck collar will not let your neck move so far because as your neck moves the helmet comes down on the collar and the movement is restricted.
