Just a thought on "where parts come from".? I have had many discussions about
USA vs. China, Mexico, Germany et al. regarding quality with an engineer friend
(retired chief engineer for MTD Corp.) who is now designing and having made
high quality bearings and seals amongst other products.? While some across the
globe may make inferior products, most times the fault lies not in manufacturer
but in the specifications they were given for their design.? If a companies
main goal is "price" then the spec will be looser and quality will suffer.? He
tells a story of some prototype bearings he had made up for a major US blender
company.? In testing they kept burning out and he couldn't figure out why.?
Upon analysis he discovered that he had "spec'd" the bearing so tightly that
the race had been machined so finely that there was no porosity which allowed
the lubrication to fly off and thus burn out the bearing.? He had to relax the
machining spec to correct the issue.? Yes, those bearings were made in China.?
I guess the moral of the story is you never know what your going to get in
todays world and to try to do some study on "real world" purchaser evaluation
before buying, ie., don't do the road testing on a new product for a
manufacturer or distributor.? Just my two cents.

I have the Centric parts line and would be happy to quote - friendly prices.?I
can say that I have used their rotors for years and they are very good quality
- used on all my company vehicles and personal cars. That said I have never
used the Centric rotors on a race car - but have sold 1,000's of their StopTech
branded rotors for racing and they are also very good. Some of the StopTech
rotors are cast in the US and some outside the US including China. Today with
AutoZones etc dominating aftermarket sales it's hard to compete only sourcing
?domestic made rotors. 90+% of the market is private labeled sourced from who
know where. Regarding Centric ?(and other high volume manufactures) they don't
just source this stuff on the web. They buy significant production from
foundries and have quality control people at the foundry.?
I've never purchased drums but did enquire ?about the GT6 drum and they do not
have those. They also do not have the GT6 1/2" x 9.7" rotors.?
I am planing to make the 9.7"X 1/2" GT6 rotors at my shop but they will be 2
piece with an aluminum hat. I anticipate a selling price of $300 ea. For the
assembly. Just finished a similar kit for the Ford 289 and 427 Cobra. Picture
of dyno test below. GT6 is almost a miniature version of the Cobra rotor
assembly. They will be bedded in and ready to run.
Brembo has foundries all over including Mexico and Michigan.?

Subject: [Fot] Public Service Announcement, knockoff Datsun brake drums
A couple years ago when I was accumulating parts for my TR250 vintage racer I
sourced a pair of brake drums that I knew were aftermarket copies of the Datsun
240Z finned aluminum drum. These copies were getting decent reviews at the
time, so I tried a pair.
So I am prepping for the next event and found this. These drums ran 8 weekends.
The other drum shows a small crack, looks like it would grow to look like this
one pretty quick.
So anyone have a source for some real Datsun Z-car drums?
