How will this be judged?

Re: How will this be judged?

The F41 components on an L36 car will receive a FULL DEDUCTION. This is not governed by CDCIF. Please refer to section 9 of the Standard Deduction chart entitled, "Added or Deleted Options". Hope this helps.

Tony,

Wow. I didn’t expect that answer. Just to cement this in my mind, as another example, if a car has an F41 front sway bar, but was born with and has standard suspension components for everything else, it’s a full deduct for front and rear suspension?

Gary. If the car was born with standard suspension, but it has an F41 front sway bar, then the owner would receive a full deduction for the front sway bar. Each suspension component is independently evaluated.

Hope that helps.

Tony, not to beat a dead horse, but I assume you are saying the car will get an 8 point deduct for just the front springs and not 140 points for the whole suspension.

Thanks again,

Don

Re: How will this be judged?

Good morning, Don. Remember, we independently evaluate each line item. So if your friend's L36 car has F41 springs, and no other F41 features, then only the F41 springs would be subject to the standard deduction.

Judges seem more in tune with CDCIF, so naturally they evaluate based on CDCIF analysis. That is understandable. A less experienced chassis judge could make a call based on CDCIF. However, F41 was a production option, so it is subject to item 9 on the standard deduction chart.

I hope this helps!

Best regards,
Tony

Re: How will this be judged?

How does one differentiate standard vs. F-41 front springs once they are installed in the car and the car is sitting on the ground in judging position?

Rear springs, sway bar, etc, are easy.

We still don't know how the judge can even tell it's not a standard spring.
My thought is that it's quite difficult, and won't be noticed.

Patrick. Actually, the F41 spring has a much wider coil spread pattern than a standard spring. Come by the C2s some time and I'll be happy to show you.

That's what I was looking for - both for me and for others reading this thread.
I haven't judged Chassis much in the last decade unless the car is on a lift. My vertigo doesn't appreciate me laying on the floor with my head tilted.

Re: How will this be judged?

You have vertigo too? It is miserable. I can't lay flat on my back and look straight up.

Thanks for your posts! They are always welcome!
