For discussion:

I posted this request to the comp Board, Ref Letter #279:

Sent: Sunday, November 29, 2009 11:17 AM
To: Club Racing Board

Subject: Request for competition change - ITCS

Gentlemen,

Respectfully request your consideration of the attached
change to the ITCS. Reference (2009) GCR, page 349.

This request is being made due to NLA (No Longer Available)
status of the rear brake drums for these vehicles. Reference the
following from one of the primary suppliers of Nissan and Nissan Comp
parts in the US:

(Inserted link to Nissan Comp website where Datsun rear brake drums are shown as NLA)

What I requested was:

"Alternate Brakes are allowed (R) 258 or 269 Solid Disc and calipers from 280-ZX."

For all of the Datsun's with drum rear brakes.

This was the Comp Board's answer:

2.
ITS – #279 Request for alternate rear brake assembly

This request is not within the IT philosophy.
For Reference, this is what was historically allowed for the Old Calais/Achieve/Pontiac Grand Am:

"Alternate rear bearing, flange, and disc brakes from (General Motors) Saturn are allowed. 16" wheel not allowed"

Does anyone know the history of this change that allowed the Olds/Pontiac's to change from rear drums to disc brakes?

I honestly felt that there would be no competitive advantage to this, only that the rear drums are out of production and that with the use of a stock Maxima rear bracket, the 280ZX discs fit the 240/260/280Z's.

Appreciate any comments and other viewpoints. What philosophy did this not follow? How was this different from the Olds allowable alternate?

Thanks!

A.
