R3 Head and Neck Restraint Systems - Frequently Asked Questions
Does installing the D-rings involve drilling holes in
the helmet? If so, what does that do to the SNELL Rating?
Installing the helmet anchors does involve drilling holes in the helmet.
The Snell Foundation
has stated that so long as the drilling is done outside
of the test zone, it does not affect the helmet's
certification. The anchors used for the R3 are not in the test zone. Each
kit includes the helmet hardware and installation instructions
for easy do-it-yourself installation.
My helmet has HANS anchors installed. Can I use
the same helmet attachment points?
If the previous hardware installation was done accurately, the R3 can use
the same holes. We recommend that you check the hole
location per the R3 installation instructions to make
sure they are correctly located.
We have seen some helmets with improperly located attachment points. If that is the case with your
helmet, you may have to drill two new holes. Helmet
manufacturers generally don't recommend leaving the
old, unused attachment hardware in place. If you
need to cover any old, unused holes in your helmet,
a couple of strategically
placed decals may be your best solution (or you could
call them small, custom ventilation holes). Note: While it is technically
feasible to use the the R3 with HANS quick release
fasteners, the manufacturers of the R3 do not recommend this. If you decide to use
the HANS quick release fasteners with the R3, you must
make sure to adjust the helmet attachment straps to
the correct length.
I currently use a D-cell with the cables kit on the helmet. Does the R3 require D-rings or can it be connected to the existing cables?
The R3 would require the use of D-rings accurately mounted per the included
instructions. The D-cell and the Hutchens Device both
use the shoulder of the occupant as the pivot point
for the helmet tether. The R3 uses
a higher helmet tether mount, which requires a more
rearward mount on the helmet. If you need to cover
any old, unused holes in your helmet, a couple
of strategically placed decals may be your best solution
(or you could call them small, custom ventilation holes).
How do I determine whether to use the Formula version
or the Sedan version for my sports racer?
You should measure the seat back angle just below where the shoulder
harness passes through the seat back (the angle is
measured from horizontal). If the angle is less than
65 degrees, use the Formula
Car version. If the angle is between 65 and 80 degrees,
use the Sedan version.
If your seat back is VERY vertical (between 85 and
90 degrees), we can order the Sprint
Car version for you (we don't currently stock the Sprint
Car version).
Are quick release tethers standard on the R3 or are they extra?
The R3 comes with the quick releases as a standard accessory at no extra
charge.
