Hey guys, I am reading through the rule book, trying to sort out some equipment. Specifically seats...
The car is a 2013 Subaru STi that I am hoping to go over 200 mph with...So that should help with what class and the amount of safety needed. I am trying to go over on safety because...well...I care less about doing the bare minimum to go fastest and more about being safe and just having fun.
I am going to have Shuken racing build the cage etc and we were in the beginnings of the conversation about the rules etc...He mentioned to look closely about the head safety stuff, as its gotten more strict recently.
I will be using a Hans device... I love them, I swear by them... I was a PIT instructor at my police department and getting PIt'd 600 times every thursday was a much less pain in the neck with using it...
So the rules say in 3.A.3; ...The seat roll cage structure.... shall provide restriction to lateral head movement of less than two inches per side inclusive of structure deflection, and at minimum extend to the forward most portion of the helmet, see section 3.B.1...
3.B.1 says that there needs to be a minimum of 3 inches clearance to the Helmet....
So I am confused...
Does this mean, my HANS device needs to restrict movement to less than 2 inches, or that there needs to be a physical barrier to limit travel to 2 inches?
And then finally...The seats I was planning on using... SABELT GT-300
http://www.sabelt.com/en/racing/Products/allestimento-vettura/sedili/Pages/04GT-300.aspxThey have extensions to reduce helmet pinball against the chassis/window/cage... Does this qualify as to the restriction that limits movement that has to protrude out in front of the helmet?
Or do they mean the roll cage has to be built as a cocoon that surrounds the driver and the vertical bars left and right of the drivers head need to be a few inches from the head, and be built out in front of the helmet...So you kind of sit inside of a cage inside of your cage inside of your car? (If that is the case I would go with the SABELT GT-200 where there is not the head extensions and allows a little more side view...I will also be doing track days with the car and it helps to see your mirrors! For reference on that seat:
http://www.sabelt.com/en/racing/Products/allestimento-vettura/sedili/Pages/05GT-200.aspxWill this seat/Hans device count as legal for the above rules...And then of course add into the mix the cage to be built around the whole thing?
Also seat material... This is an FIA approved carbon/composite seat. Section 3.D.1 say composit seats need to be approved by the tech committee.
Thanks for any guidance on this. I hope these questions arent too confusing.
Off to read more rule book!!!
