They got the parts orders, Wheel magnafluxed, Do a complete tear down every break in racing they get, everything gets the once over or replaced, etc However in many cases they save you $$ in less failures. |

Thank you Mr. Corky!
Ironically, the cross sectional area of the 1.25-.095 tubing is greater than that of the now required 1.375-.083. |

Re: concerning a recent thread about costs of racing
Good to see discussion of this subject. What, if anything, is known of the failure mode(s) that are addressed by this change? Column failure in a roll-over? Transverse failure in a side impact? These two combined?
A slender column of 20-some inches is quite vulnerable to both eccentric column loading and transverse loading. That loading can be reduced by ~1/2 by adding a horizontal hoop that ties together the B-pillars and the A-frame tubes. |
Re: concerning a recent thread about costs of racing
This thread is a total waste of time. Racers and owners are their own worst enemy. Every single dime you cut on cost in one area will be spent somewhere else. You will never save these guys money. I have a buddy that runs a "Crate" Late Model. He switched into that class to save money. You know motors are "supposed" to cost a fraction. Well guess what to be competitive his motor cost is almost double what it should be. He is saving some money, but nothing like he should be. O ya he is running for far less each night. So anything he is saving by running the lower class he is losing in pay difference.
