Alternate 240Z rear brakes...?

[JeffYoung]

Good point and not sure Bill. The "conventional wisdom" is that we have to wait for a letter, but then again, ITAC members have written in letters to start a decision making process on a car/issue.

I should do that. I think I will.

Oh, they have a letter on it. It's on the ITAC agenda. Number 639.

I think it reads something like this:

Sirs,
The line item exception allowing the olds in ITS to use alternate brakes in the rear dates back to it's days in SS, and it carried the exception into IT from SS. It creates a situation where it sets a precedent for other exceptions. Z car drivers want to be allowed alternative brakes to help avoid issues with getting the preferred aluminum drums, RX-7 drivers want a new plating process to help continue now unavailable rotor engine parts. Once the barn doors are open, and all that.

I suggest the exception be stricken with the Olds. A sunset clause should be added should there actually BE any racing anymore.

Sorry for jumping in but I was talking to my dad who raced back in the 50s He said that rellinng the brakes was common. Most of the euro cars ran allum. drums, and I think that is where Nissan got the designs from. I looked at an old set and they dont look that hard to do. I think some people need to look for some of the old school or vintage people to see if anyone would still be able to do this. He noted that there was a lot of crative materials used back then to "improve" the drums. Remember they ran drums on the F1 cars at close to 200mph and they worked just fine. As long as SCCA allows you to refurbish them I see an opertunity to improve the originals. While it may not be the most inexpensive route if you can inprove the performane of you old drums it might be worth the cost??? If someone came out with a "HOT" drum setup for the Z car it might sell to the steet guys also this might get some people intrested in a larger production run and lower cost? Just a thought.

Guys

Finally got registered from lurker mode.. I am talking to my machine shop buddy about re-buildeing the pile of cracked drums I have. My thought is to machine out the existing steel/ iron ring, and theremal press in a replacement ring. would you guys be interested in such a service ? I am shooting to do a first prototype pair and run them this spring. what would be an acceptable target price ?

Thanks

what were the results of your drum rebuild? I have found a source for re-lining al drums but he does not have the tooling setup for the 240z and would like to know the potential market. Send them a note to give them an idea how big this market could be.
