I have a couple questions guys, I need the rule gerus!

Rules-

13.5 SHOCK ABSORBERS
A. The make of shock absorbers, struts, and strut housings may be
substituted providing that the number, type (e.g., tube, lever, etc.),
system of attachment and attachment points are not altered, except
as noted below. The interchange of gas and hydraulic shocks absorbers
is permitted. The following restrictions apply:
1. No more than 2 separate external shock damping adjustment controls
are allowed. This permits the use of shocks which originally
came with more than two external adjustments, which have been
converted to double-adjustables, only if the additional adjustment
controls have been permanently disabled (e.g., via welding, epoxying,
grinding off). Gas pressure adjustment is not considered
a damping adjustment.
2. Suspension geometry and alignment capability, not including ride
height, may not be altered by the substitution of alternate shock
absorbers. Aftermarket strut housings are allowed provided that
they meet the Stock category shock requirements defined herein
(i.e., that no suspension geometry changes result). This includes
the position of the steering arm attachment point in the case of
struts with integrated steering arms.
3. Adjustable spring perches are allowed, but the spring loadbearing
surface must be in the same location relative to the shock mounting
points as on the standard part. Shims may be used to achieve
compliance.
4. The fully extended length must be within ±1” (±25.4mm) of the
dimension of the standard part.
5. Electronically controlled shocks may not be used on vehicles not


This came up in my for sale thread, since my shocks are 3 ways can I really just remove the rebound knobs and be legal? It would be removing a adjustment from each shock so I would think yes but wanted to clarify! My other thought was scribe a line on the high speed and low speed adjuster and if some cry baby wanted to protest me because I'm better then them just say "look the lines are lined up, they aren't being used as seperate adjustments. My other idea was to some how make a clamp that makes it one knob but that would be a challenge. Removing the rebound knobs would be the easiest, most sure way to make them doube adjustable and not have to worry about protest.

The other issue is my rear shocks overall length is 6-7/8th of a inch shorter then stock which falls within the 1" rule so no issue there. The problem I have is rear droop and lifting that wheel off the ground. If I was to build a stock class shock I would actually build it longer then stock since the travel isn't a issue at stock hieght for the extra droop to keep the rear tire well planted. With the shorter shock the wheel will lift off sooner. My question is can I make a 1" spacer that fits on top of the top hat to extend the shock length 1" and fix the droop "issue". Ofcourse I would take that spacer into account on spring location so that it remains at stock ride hieght. The other option would be spend $400 and switch my rear shock bodies back to the original longer ones to eleminate this issue.

All pending I don't sell the 3-ways

Thanks!

 

Want to sell your triples for my DA Penskes? Problem solved!

 

You could just disable high speed adjuster. Scribing line is not it, by the rule.
Your droop is dependent on preload you have on spring. Whatever your car compresses shock from its free length is your droop. Do you have internal droop spacer?

 

Some people use a little blob of silicone to show a knob being non-adjustable, I think.

 

Or epoxy like it say in rules, than you know you legal.

 

Ckit- maybe with some money, PM me if serious.

TWF- yes you are correct but note the stock shocks don't have and helper springs on them. Think about this..

If the shock is shorter then stock in overall length and the lower spring perch is required to be the same distance from the bottom hole to the spring perch as the stock shock I may run into issues. Ultimately the result would be a spring that has 6-7/8" preload in it. Make sense?

With a 6-7/8" spacer on top of the tophat you can move the spring perch down 6-7/8" and remove the preload in the spring while keeping the stock ride height. Maybe I need to just pay the money and switch back bodies.

I agree the scribed line may be a issue for people wanting to protest me because they can't beat me any other way. I think the simple removal of the rebound adjuster knobs would count as making it only two way adjustable since ultimately the shock would only have two adjustments. Hmm.

 

Silicon works.

 

Yea not putting Epoxy on highend shocks haha

Silicone would work! Easily removable!

 

Use shorter springs.
As long you can't adjust it when taken of you should be fine. I don't know what adjusters look on those things but if you take knob of and there is way to turn it with screwdriver or anything it is not disabled.

 

That is the problem, easily removable and siliconed again, you could do it between runs. You better pass that by whoever is in charge.
