Not exactly, Jake...what I'm "saying" is that to the letter of the rules threaded body shocks are allowed in any form - even to adjust the perch. They are allowed because they are not disallowed. Follow me here...
- ITCS D.5.b.1 allows alternate shocks as long as the pickup points are unmodifed. There are no restrictions to those shocks within the pickup points (except for remote reservoirs and # of adjustments); therefore absent further restrictions threaded bodies are allowed.
- ITCS D.5.b.2 allows substitute struts, inserts, modified spring seats, doing the same as above for struts.
- ITCS D.5.b.3 allows alternate suspension springs, as long as they are of the same type, thereby allowing adjustable coilover suspensions using racing springs.
- ITCS D.5.b.4 is in regards to leaf springs.
- ITCS D.5.b.5 prohibits permanantly attached threaded sleeves to a strut or shock absorber.
Therefore, the prohibition on threads applies to SLEEVES, not the shock or strut bodies themselves. If you don't use sleeves, then threads directly on the body of the shock or strut are, therefore, legal.
Now, one could argue that struts with inserts have parmanently attached sleeves to the damper, but it would be a weak argument; I would counter that inserts can be removed therefore the "sleeves" are not permanently attached, and I can also argue that to support that point would mean that cars with shocks versus struts would have a distinct and unintentional advantage.
I'm not ignoring Darin's last post; it's well-noted and I hope the foreshadowed premise comes true. Regardless, I offer this post simply to explain why I think that to the letter of the rules and not to the spirit of the rules that threaded-body shocks are legal.
Bottom line, if the purpose was to ban threaded-body shocks and struts, it's poorly worded and is only supported in practice due to long-standing assumptions and expectations.
