I figured this information needed a separate topic for comment.

Now that the rules are in and finalized for 2015 compliance. 

[wheel]

The part number for the bushings is not part of the final rule.  That rule says:

MOTION: Approve add to #15634 – 9.1.7.C.3.p: Inner bushing(s) on the front upper control arms may be replaced with offset bushings. Hanushek/Butler. PASSED 11-2 Against Langlotz, Lindstrand.

 

[Steve Scheifler]

Was there an opposing argument that can be shared?

[Dave McAnaney]

Mazda does not offer an offset bushing for the front upper control arm, so the part number reference was removed.  Any offset bushing may be used in the front upper control arm.

bushing, not bearing

[Chris70]

It is a metal bushing :-)

No mention of material :-)

MazdaSpeed Part Number:  0000-04-5409  

$66.66 for the set

 

My guess/hope is SMAC just over looked it in error.   Nevertheless, this will be the spec part number in the 2015 NASA SM Rules.

can someone post a high res photo of a plunge cut with a 1.5mm deburr ?

A couple of things:

The Mazda bushing is not in stock.  Those SCCA members racing next month cannot get the Mazda bushings.  A spherical bearing is not a bushing and would not be compliant.  Who really cares what material is used for these bushings?  You can make them out of unobtanium and they would have no measurable difference in performance over the Mazda bushings.  So, build some bushings, buy some bushings, just don't show up next summer with non-compliant bent spindles.

I know, I know, rules are rule, but...
Either way gives you the camber.
So no advantage..

Just saying,

The wording in the link above calls out the "Mazdaspeed offset bushing" which is then referring to only the part john has listed.
Is there somewhere else the wording is different?

So 1st, someone posted it out of stock @

2 it says "Busing kit, Frt Inner"

 

3 there's been some debate on weather you want upper or lower and what this kit is.

 

The news release today was posted in between Fastracks, with people I heard were on vacation to get us a answer on the rules.

It's approved but there's some work in process in getting us the parts, IMO.

[john mueller]

I have a call scheduled with some folks in the know at Mazda tomorrow.  I'll have more info then, hopefully.

Topeka letter dated 12/18/2014

 

Additionally, recommended changes to the front suspension were approved. Rule 9.1.7.C.3.p now reads “Inner bushing(s) on the front upper control arms may be replaced with the Mazdaspeed offset bushing.”  

[Todd Lamb]

The rule will read that ANY offset upper bushing is allowed.

 

We ordered 4 sets Monday - will be installing soon for Homestead.

Got a link?

With Johns update, I got in line to get a set for 2015 with NASA. So now that I bought a part that I have no idea how it works...what do I do with it? I think I know where it goes and I know what it is suppose to do but a "how-to" would be cool.

 

Time for a new thread?

Whose playing games, I copied both statements from the letter that Race Engineering posted to start this thread.

 

EDIT:

And on 12/18/2014 from the Topeka letter I copied and saved the following.

 

"Additionally recommended changes to the front suspension were approved. Rule 9.1.7.C.3.p now reads "nner bushing(s) on the front upper control arms may be replaced with the Mazdaspeed offset bushing (part number 0000-04-5409).”

This is the process for installing bushins in the front upper control arm. Don't know if these ISC Rcaing bushings are legal.
