    Hey guys, what is the detail with what we can and cannot have in Stock classes with our Shock setups? No more triple adjustables right. Are external resevoirs legal, if it is Double Adjustable? Is Nitrogen Charging legal?
    Thanks in advance!

    Dave,

    What are the "new" shock rules to which you refer?

    Are they different than these: [url="http://www.moutons.org/sccasolo/car_class_rules.html"]http://www.moutons.org/sccasolo/car_class_rules.html[/URL] ??

    AFAIK, external reservoirs and nitrogen charging is legal, regardless of being double adjustable.

    OK, I'll admit my ignorance here: I know what a double adjustable is. What is a triple adjustable shock?

    Jim

    Those look like the older rules, from last year. I believe for 2002 they said no more triple adjustable. Not sure of the eternal resevoir, or nitrogen. An example of Triple adjustable is you have the typical Compression, and Rebound. However a triple adjustable offers low speed, and high speed compression adjustment.
    Thanks!

    I've not heard any rumors about that, even for something as far off as 2002. Where did you get this? I franky would not object to limiting shocks as you outlined.

    Ok, I found it... December 2000 Sports Car issue, Fastrack. Section SOLO, Item #6) Reads, 'Add to section 13.5.A the following: "Substituted shock absorbers may provde no more than two external damping adjustments. Remote reservoirs are permitted and holes may be drilled for bolts with which to mount the reservoirs, but bodywork may not be additionally cut or drilled to provide for the routing of lines or the positioning of the reservoirs." Comment: this does not afect the Street Prepared rules, since for that category it is overridden by 14.5.C'

    So there it is... Guess externally adjustable is still legal, but only a maximum of 2 external adjustments!
    Hmmm,

    I think the stock shock "clarification" came up because of a mega-buck system Stacey and Laura were using on their C5 this year. I think it had external reservoirs, but I'm not sure about the number of adjustments.

    Jeff Fields once said to me that he stayed with single adjustables on his V6 Camaro because double-adjustable just means one more thing to screw up. SCCAForums Image

    Ok so call me the ignorant/stupid/newbie whatever, but what are the two/three adjustment shocks?

    A typical single-adjustable shock usually either adjusts compression damping and rebound damping together, or just adjusts rebound, compression not adjustable.

    A double-adjustable shock would allow independent adjustment of compression and rebound, allowing a higher degree of tuning.

    A triple-adjustable would further this with low and high speed rebound adjustments. This would be particularly useful on a rough surface as it would control body motion better, but still be compliant for bumps.

    A quad-adjust would do the same for compression.

    So, with the new rules, you can only have two external adjustments. No more tripple or quad adjusters!

    This doesn't mean that shocks can't be tuned, just that it could be more work/luck. Some shocks are rebuildable with different speed sensitive valving. This can be used as an "adjustment", where the external knobs will scale both low and high speeds together. Pretty much not adjustable on-site at an event, but also much cheaper.

    Like $2000/set versus maybe $5000 and up. SCCAForums Image

    Eternal? Do those come with a lifetime guarantee? SCCAForums Image

    anyway, the rules _proposal_ for shocks was published in the December 2000 Fastrack, quoted below:

    "ITEM 6) Add to section 13.5.A the following: "Substituted shock absorbers may provide no more than two external damping adjustments. Remote reservoirs are permitted and holes may be drilled for bolts with which to mount the reservoirs, but bodywork may not be additionally cut or drilled to provide for the routing of lines or the positioning of the reservoirs. Comment: this does not affect the Street Prepared rules, since for that category it is overridden by 14.5.C."

    Eternal, external! :-) Whoops... Maybe Eternal would be a reservoir that went every where I did! :->
    Thanks Craig!

    Doc,

    Thanks for the knowledge... I can then assume that my (rather simple) KYB AGX's will still be more than legit for Stock class, as they only adjust 1 setting.

    Thanks again!
