LOUDON, N.H. – The NASCAR Whelen Modified Tour returned to New Hampshire Motor Speedway Saturday for the running of the Whelen 100.
A dramatic final lap saw Ryan Preece go from third to first in the final corner to capture his first series points paying event at the facility.
RaceDayCT’s Fran Lawlor spent the day roaming the grounds of New Hampshire Motor Speedway. Check out his gallery below.
Thanks, great photos.
NWMT rule book
20D – 12.1 Coil Springs
All downward chassis movement while the race vehicle is in competition must
be limited only by the normal increasing stiffness of the springs or the bottoming
of the chassis against the race track, whichever occurs first. Any device or
procedure that in the judgment of NASCAR Officials attempts to detract from or
compromise the above will not be permitted.
This rule was made to prevent coil bind spring designs and bump stops. Looks like 44 car LF spring is coil bound, unless Nascar considers infinite stiffness from coil binding as normal increasing stiffness. Pretty much any car with jack bolts on the front coilover upper mount is coil binding at least one front spring if the team knows what they are doing. Good photos, thanks.
Well, a coil spring as allowed by NASCAR, including uniform diameter, uniform wire diameter, equally spaced coils, etc. is a linear spring, and does not change stiffness. Stiffness is another way of saying spring rate, and the springs are supposed to be linear, constant rate. Variable rate springs are prohibited, or so I have been told that’s what the rule is supposed to control. So I have always wondered what exactly is meant by “normal increasing stiffness of the springs”. Can it also include any decreasing stiffness of springs?
The force, or load, the spring exerts is purely a function of the change in length. The change in length of a spring as defined by NASCAR is a linear spring and can not change stiffness, or rate, with a change in length.
From the rulebook: “Progressive or digressive rate springs will not be permitted.”
That means that the spring rate (stiffness) must be linear and shall not change. There is no such thing as normal increasing stiffness of a linear spring.
And from the context of the rules it is clear that any means to deliberately limit suspension travel by something other than the springs is prohibited 🚫.
That rule on springs would make sense if NASCAR changed “stiffness” to “loading”.
