GCR 9.4.C sections 2 and 3 exempt IT, SS, SM and T from the requirement of having a cage tube that extends from the forward down tube. I think STU and STL should also be included in this exemption as many of these cars cross over and without that tube, you risk running a fowl of the rules.
Thoughts?
p.s. letter already submitted, but wanted to see if I am out of line
It's actually already in our agenda to discuss...Quote:

- Require them in Improved Touring (and SM, T, and SS).
The former idea goes against the grain of those who believe lack of these "optional" bars is a true safety hazard; the latter is opposed by those already in those categories that want to keep them optional. Some scrutineers feel that our allowances of cars into ST prepped to other categories also exempts them from the additional safety requirements, while others feel that it does not.
My personal opinion is that from a safety aspect these bars should be mandatory for all categories, and I suspect the vast majority of the cars out there already have them in some form (or they can be easily added). But in the end, that's a decision the CRB is going to have to make.
As noted, it's in our agenda for discussion. - GA
I'm thinking it is already covered.
GCR listed IT cars,85 and newer,under current IT specs.
Cage is ok in IT,should be OK in ST under this rule. Correct? or did I miss something. Or did I just over simplify this?
Why add more words to an already wordy book.

Tx. Part of me knows I should have these bars, but my wallet is talking louder :(

These tubes are required in Super Touring...Quote:
One tube must extend, from each front down tube, forward
to the firewall or through the firewall except in vehicles in
Improved Touring, Showroom Stock, Spec Miata, and Touring.
This tube, one on each side, must connect to the chassis at a
point not more than 12 inches forward of the front axle centerline.
Cars competing in Improved Touring, Showroom Stock, Spec
Miata, and Touring may extend one tube, from each front
down tube, forward to the firewall, bulkhead or wheel well,
but not penetrating any panel.
Depends on whom you ask. "Some say" that our allowance for IT cars to compete in ST under their IT prep rules does not waive the GCR rollcage requirements for cars competing in ST. That has not been formally clarified.Quote:

And this is my point... An overreaching tech inspector could gaff you if they wanted to. Heck, I once had a note in my log book that said "paint must match"... Really?Quote:

IT cars prepped to the IT rules are allowed to in ST as is. The GCR is clear on the subject as written as of the December updated version:
"Any GCR listed IT cars, 1985 and newer, under their current IT
specifications may compete in STU. GCR listed IT cars of 2 liters
and less engine displacement, 1985 and newer, may compete in
STL under their current IT specifications.
Note: While IT cars may not be competitive in the ST category,
their inclusion in the category will allow regional competitors to
participate in national events."
You're "preaching to the choir", Jerry. But I'm hearing not everyone thinks that way, which is why we're going to clarify it.
Actually, there is a third option: CRB comes out and formally says that "IT prep" means everything, including safety items.
GA
I am sure Greg will correct me if I am wrong, but the last rule set I saw said fuel cells are required only if the fuel tank isn't located between the axles and frame rails. So no, a fuel cell isn't required.Quote:

But again, I could be wrong.
That's bad rules reading - it's an IT car, with an IT cage. IT cars may run in ST. The car is legal.
counter example: if you wanted to run in Production, and ran a non compliant cage, then the tech would be correct to point out that your car did not meet minimum production safety requirements as the PCS does not state that IT cars may compete in IT trim. The fact that some IT cars meet production requirements does not mean that they must or that those which do not may run as production as-is.
the STCS specifically states that IT cars compliant to IT rules may run in ST.
If this is really a problem, write a letter to the ITAC and request that the cage rules in the GCR be referenced within the ITCS, then a car prepped to IT regs is specifically compliant in ST with a cage that does not meet ST rules.
I agree completely with this interpretation. The problem will become the first time you make any modification that is allowed in ST and not in IT all ST requirements kick in.Quote:

additional IT cars that ARE legal in ST even though they aren't compliant to the ST rules (I am not arguing against this, just pointing out that the people readng the cage rules are missing other opportunities to be wrong):
1)ANY ITR car running the maximum allowed wheel rim width for ITR (8.5") in STU or L.
2)Integra type R or S2000 (2.0L) built to ITR rules in STL
3) any 2ZZ-GE powered car (ITR Celica GTS, ITS Corolla XRS) in STL (too much valve lift)
4) Many cars which are underweight by the ST class rules when running at ITCS prescribed weight, such as the Mazda Protege ES 2.0L (ITA), Lexus IS300 (ITR), Nissan 300ZX (ITR or ITS), MAzda miata (ITS), etc...
WOW :blink:

We had the weight argument in tech. It cars got to run their IT weight after much ado.

Engine coolant lines in the passenger compartment:Quote:

It allows disconnecting/plugging of the lines. SS, SM and T do not specifically allow removal or plugging of the lines or heater core. So any car from SS, SM or T - that want to enter in ST, MUST eliminate lines conatining engine coolant from running through the passenger compartment. IT cars can plug them, since this is allowed under their rules.
One of the key goals of the mid-year re-write of the category philosophy (the whole front of "the book") was to do just that. I suggest unless there's something missing from there, all one really needs to do is read the opening sections of the Super Touring Category Specifications.Quote:

Keep in mind that the regulatory issues at hand here are ONLY GCR main body SAFETY issues, such as roll cage, cell, etc. if someone is getting their ITx car bounced because of weight, prep, cams, etc then it's solely due to people not reading the regs. There's not much we can do about that, and the protest/appeals process is your friend.
GA
Edit: Also recall that I wrote a CRB column in SportsCar (the issue that arrived immediately after the Runoffs) bringing all this to the attention of the membership/hierarchy...
While there are legitimate (but IMO, incorrect) disagreements in regard to the safety questions, I kinda think we've done our homework, but you can't FORCE people to read the regs for the other stuff. "Horse to water" and all that...
any update to this? do we see the rule getting changed to make it an optional tube for ST?
No, that request was rejected. Run under ITCS regs and you're Ok. But as soon as you build it for ST, you need the tube. - GAQuote:
