Caster in the rf raises that corner when you turn right. It has a big impact on the old static deck height measurement. It has some effect with droop measurement, but not nearly as much.Quote:

its a pain in the butt rule, especially if you change something other than the limiter and didnt check it, but is what it is, i would say everyone is going to fail one time or another, but the regulars do get away with a ton more
and no doubt if they did jack it up fast and he had a ton of rebound in the rf and they did get the lr off the ground, i would agree with him, but i wasnt there, so cant say
i could give a very creditable answer on this about changing the rf springs or rebound but never touching the limiter, and the deck height would end up different, not alot but enough to through you out ??? dont know
and let me say i never heard how much it was out
I enjoy your knowledge and input 👍Quote:

Mason Ziegler went to the back of his heat race after a flat and made it into the show. And if you didn't qualify through the heat and moved up, he still would of had a great chance through the bmain where they took the top 4.Quote:

Sorry but his excuse holds NO water being that far out
Shouldnt they have a designated area so all competitors are treated fairly?
Why is it even an issue?
From an engineering standpoint a shock can generate a force only when it is being compressed or extender and the force is proportional to the velocity that that is occurring at but when they’re measuring droop the vehicle at that time is sitting totally static I am not a racer just an engineer so maybe you guys can tell me whether a racing shock has some spring characteristics to it as well that could hold a load when it is static otherwise I don’t see where Ricky’s argument would hold water unless there is a stiction component that could also come in to play
Good question!
Don’t know if it’s a good question or not … engineer and long time dirt late model fan and I try to look at things from a engineering perspective but I’m hardly a Kevin Rumley lol although physics is physics don’t know all of the characteristics of Racing shocks and such but do you know in its most basic form first year of engineering school you learn about a mass spring dampener system where in this case the mass is the sprung weight, spring is the coil or leaf springs and the dampener is a shock absorber doesn’t matter whether it’s a linear spring or a progressive spring or bump stops which would all be categorized as springs at the end of the day the static position on some thing is based on mass and springs nowhere in the equation does velocity come into it you could have an orangutan jumping up and down but when he jumped off where it is is where it is let him do it again and it will be in the same place which would be contrary to what Ricky would claim… but my thoughts are totally from a theoretical stand point but I think the Armstrong weight is enough to bring it back to the same point every time regardless of any velocity inputs
Shock question:
These rf shocks have so much force at "zero" speed, that they can hold the wheel in place for a time or a least make the "return to zero" take a very long time. Its a crutch to make the cars take advantage of the aero. The rr often has a lot as well. Its another crutch to deal with the fact a 4 link suspension has issues.
These are massively over-damped systems, to give you some engineer speak.
He failed the droop rule by 1 1/16 of an inch.
In reference to post #29: he did load up his car - but didn’t leave. He had his pit box, Jack ect. Out helping other teams.
Thanks ray cook
Thanks for nothin……..
Yes. Thanks for nothing
XR series will no longer enforce the "droop rule" the remainder of 2022.
