But, potentially someone could challenge based upon safety. Nobody has ever challenged on that particular basis, it would likely prevail.
Not only "what Phil said," but the SEB pretty much never makes specific allowances for safety or reliability.
If it was safe enough to be a road going car, it is safe enough to autocross. The only example I can think of - and Phil likely can think of more - is the limiter strap for swing-axle cars.
While not a _safety_ issue, a good example of the SEB's unwillingness (and rightfully so) to go down a slippery slope of one-off allowances is the timing chain tensioner on Porsche 911s. Early (uhh, pre-82, maybe?) 911s had failure-prone timing chain tensioners. Later cars had hydraulic tensioners. Swapping the hydraulic tensioners into the early motor results in zero performance gain, but a lot of perceived reliability. MANY people campaigned to get the hydraulic tensioners specifically allowed, it was denied.
Addertooth - making statements like "Nobody has ever challenged on that particular basis, it would likely prevail" is flat wrong. If ANYTHING, if the SEB were convinced that a car were inherently UNSAFE, they're make recommendations to have it disallowed from competition - they won't put in a line allowing some-something for Eliges.....
.....because then the Hupmobile owners will want a billet disgronifier valve, and the Corvette people will want a gold chain holder and the Camaro people will want something and so on and so forth.
This forum (lotustalk) is really pretty good, but there's a LOT of misinformation here stated as fact in the Solo forum - those who post that "no one will care" locally are right. Heck, I don't care nationally - I'd not protest on toe links, but at a certain point, rules are rules, and if you're going to speculate as to how the SEB works/makes decisions, please do SPECULATE. The SEB pretty much does not make specific allowances for specific cars.
I agree with the sentiment, though - I get the idea that if "you" argued "safety," the SEB might see that there's no harm in allowing it, as it has no physical performance advantage. I certainly thought that way when I started autocrossing. Thing is, they don't make those allowances, and for good reason - it just takes a while to see the good reason.
I check my toe links frequently. Not once have they been loose.
I've been looking at this thread for weeks, resisted the urge to reply, til now
