As far as the differential is concerned, suspension bushings are free. Chuck

How is a differential a suspension component? A live axle sure, but with regard to IRS

[chuck baader]

I'll use my car as an example. The whole rear suspension is an assembly bolted to the car in three places, each end of a suspension subframe, and the diff. All three have bushings. The rear control arms pivot off the subframe. The complete subframe/control arms/diff is the rear suspension. Chuck

Yes, in these cars (Chuck's is the same as mine) the differential is a stressed member of the subframe assembly. The whole assembly is the subframe and is attached in three places to the chassis, all with bushings. The rules already allow subframe bushings to be replaced.

This in my opinion is very different from a more traditional rear suspension. In other cases the differential is not a member of the subframe at all, but rather, hangs from it or the chassis (like a Miata). In those cars, I don't see how you could use the suspension bushing allowance to change the differential-mount bushings.

as Chuck worded it, that would work for me. need to include transmission and transaxle type of mounts. otherwise, i only have one engine mount and two tranny mounts.

just not sure why we think the CRB is going to listen to this any more than they did other topics.

and should this go directly to the CRB, i thought they said the proper flow was members to ITAC, ITAC to CRB, etc.

[lateapex911]

It goes to the CRB, and should land in the ITACs mailbox as well.

When we were discussing this, I was under the assumption that of course teh trans was included. But yea, the wording doesn't support that thinking. So be sure to mention that in your response should you support it.

Just a note, this was very contested on the con call, and passed by one vote just to go out for comment. Now that one vote (me) is gone, and I have no idea IF there will be new guys, or who they might be...in other words, it's in the balance, get your votes in for or against.

[924Guy]

I'll be getting my vote in for, with the addition of trans etc mounts too...

The productionifacation of IT is gaining speed down that well lubed slope.

Next you will all want to change the rule to allow you to remove the washer bottle and gut the doors.

Next you will all want to change the rule to gut the doors.

Uhh, welcome to 5 years ago?

WOOSH!

[trhoppe]

Bad joke, since we can't remove washer bottles

[jhooten]

Ok, I know my sense of humour doesn't play well with some people BUT
Uhhhhhhhhhh, you do understand you can't just gut the door because you want to, don't you?

[rules nerd mode] As you see in GCR 9.1.3.D.9.f "Other than
to provide for the installation of required safety equipment
or other authorized modifications, no other driver/passenger
compartment alterations or gutting are permitted."

You can remove the door trim panel and replace it with aluminum sheet but you cannot remove the door internals.

Unless, you look in GCR 9.4.D "In American Sedan, Improved Touring, Showroom
Stock, Spec Miata, and Touring the door window glass, window
operating mechanism, inner door trim panel, armrest, map pockets, and
inside door latch/lock operating mechanism may be removed and the
inner door structural panel may be modified, but not removed only if the
door bars extend into the door cavity. The stock side impact beam and
the outside door latch/lock operating mechanism shall not be removed
or modified unless specifically authorized in the category rules." [/rules nerd mode]

[MMiskoe]

"Engine, transmission and final drive mounts may be modified or replaced provided the location and orientation of these components is not altered in any way. All mounts must attach to the chassi and to the motor/trans/final drive in the original location and method."

This one should be a no brainer for the CRB to work over.

BTW why does the CRB have a link to email all of them but when you use it you get one back saying "nope, that email address is not how to get in touch with us, send your letter here"? Why not have that link right there in the FT . Am I simplifying something hard?

Just extend the door bar 0.0001" into the door cavity and you can gut the door. Not that hard to understand

Or... if your car was registered prior to 1/1/08, you get to use 9.4.2.G:
"Two (2) side tubes connecting the front and rear hoops across both door openings are mandatory. Door side tubes may extend into the door. NASCAR-style side protection, or one bar bisecting another to form an “X” is permitted. The door window glass, window operating mechanism, inner door trim panel, armrest, map pockets, and inside door latch/lock operating mechanism may be removed and the inner door structural panel may be modified, but not removed to facilitate this type of side protection. The stock side impact beam and the outside door latch/lock operating mechanism shall not be removed or modified."

But I digress...
