Teach me about ITR 325's

[Doc Bro]

metal brake caliper bushings are legal for SCCA racing. Yeah? Well, not for IT!

What part of 'bushings are free' am I misunderstanding?

The part about them being under the category rules for suspension...?

Of course, if we're agreeing that any bushing that suspends anything is free, let me know...'cause you ain't gonna like the results...just sayin'...

GA, who's really hoping our BMW friends are not replacing their rubber caliper bushings with anything non-rubber...

Mine are stock, but I thought this went back and forth several years ago...with the end interpretation being bushings are free. I could be mistaken. I thought it was around the whole spherical "bushings" and "air bushing" era.

From the GCR;
bushing- a sleeve or tubular insert, whose purpose is to reduce the dimension(s) of an existing hole. A protective liner that cushions noise, friction, or movement such as a rod end or spherical bearing.

The suspension section clearly states bushing material is unrestricted as we all know.

The brake section states that brake linings are unrestricted....what's the difference between a liner and a lining?:cool: Brake connectors are unrestricted. Isn't a connector something that "connects" the something to something else? As in the caliper to the car? Seeing how lining and connector aren't defined in the GCR I'm unsure.

I think this subject is pretty gray...as I stated before mine are stock so don't be a hater....just posing a counterpoint.

I find that all to be a ridiculously tortured interpretation.

A brake lining is the actual brake pad/shoe material. The "connector" being referred to is the hydraulic connector. That entire paragraph is about hydraulics. Context matters.

Not even remotely gray in my opinion.

+1.

But if it is, please do let me know ASAP.

But Josh those are YOUR definitions not the GCR's, The GCR doesn't define these things so variability (creep) gets introduced.

SoI guess the ITAC guys get to decide what's rediculously tortured...
Let's go back to "air as a bushing" and truly talk about what's tortured.

Of course these are all just my opinions. In my current role I don't get to decide this stuff. But in the past I have served on both protest and appeals committees, and I know how the committees that I have served on would have interpreted these situations. I think that 99 out of 100 appeals committees would agree with me. Unfortunately, too often, these things never get protested/appealed.

That past experience is part of why I have such a conservative read on the allowances.

Oye. Looks like it's time to tear some cars down in NER.

Ridiculous. Not even remotely legal, or gray.

[GKR_17]

Oh come on.. those bushings suspend the calipers right? Give me a break. Anyone remember when they tried to justify internal coatings because they were "lubricants"? That didn't fly either.

[mlytle]

some folk have trouble wih engish. suspend as a verb vs. the gcr use of suspension as a noun...

[ekim952522000]

Does anyone have a link to the bushings you guys are talking about?

And air as a bushing is justifiable in your mind....give me a break. Is air then justifiable as a washer bottle or wiring harness in your mind?

Can you cite someone/some car who actually does this and claims it's legal? I think it's bantered about but in reality it's internet folklore.
