I checked with the engineers and the difference in flex between aluminum and steel is .002". This is repeatable. Flex is not an issue. The testing was done at 20 times normal pressures.

Our departed hero...

This is what I am doing. Soda blast to clean, powdercoat in chrome.

This picture was taken in the warehouse section of Bruce Canepa's shop. If you look down in the left corner of the picture you can see part of the Frizelle car. Up above the elevator car parking system and to the right is a warehouse of rare parts that he finds and buys. On the floor just to the right and out of view is a staging area for parts to go on restorations. A great tour if you can talk him into it.

I would guess the owner to be a member here since one of the pictures in the ad is posted here...

We're good Julio. We are actually three different companies that come together for projects. In all three cases the businesses are our own. 99% of what we have done is Porsche related. I am trying to coax us as a group into the Z project. Our goal is to make no money. No kidding. We're simply trying to make available what is NLA. We're fully cognizant of the fact that the market is small and getting smaller.

Julio, Are you thinking we are doing this at work? Nope...

We have engineers. 8) Flex apparently is a function of the fastener. The fastener in this case is more than adequate to prevent flex. Oh, and to answer Leon, yes they are track tested.

Here is an example of what we are doing with 914 brakes. These are a reverse-engineered set of Porsche brakes. They weigh in at a whopping 3# each and shave 10# off the rear of a 911 or 914. They also happen to be the same brakes fitted to the Ferrari 308 series. Performance numbers are the same with the exception that they give up heat so much faster. We are thinking we might want to do the same with the Datsun Competition Sumitomo calipers if we can get our hands on a set. Pardon the Christmas marketing photo...

While this is what I had done, I think at least domestically here in the U.S. the EPA has made the regulations such that the process has gotten too expensive to survive. I got a really good deal but I was having a conversation with a patient just before a procedure and I asked what he did, "Plating shop" he said, "Oh, we have to talk... when you wake up." 8)

And weight. 8(

That didn't work for mine. I tried tapping into the factory harness to get power to the fuel pump but it the green wire wasn't live. Now, it could be that it is only live for a few seconds when the key gets turned to start and when the engine is running, but I think that requires a couple of harness changes that mine doesn't have. The relays are not there. I just went to the coil for power.

I always loved the look of this car...

Exactly.

How much do they cost though Jon? These would be in the $600 - $700 range for a set and be original looking. This is a goal I have and perhaps others as well....

Jon, I do have one in the house. I'm in the garage. I seem to recall that you're correct there was something called an FIA option. Now, wouldn't it be great if Eric and I could get our hands on a set of the Datsun Comp Calipers? We could recast them in aluminum, even put a spacer in and make a true brake upgrade. Lighter, gives up heat faster, vented rotor... An engineered upgrade without the compromises.

The brakes he has pictured are not vented best I can tell from the pic. Was there another with a spacer and vented rotor?

Nice. Four piston, not a heck of a lot more mass than the stock Sumitomo's. STILL not necessary for street use. Are these yours?

I think they are unobtainium gold! I've never even seen a set and I've been around these cars since they were new. But speaking to my original point, they are not necessary on a stock car.

Another shot of the Frizelle car.

A little 510 Rally action!

You know what would make a difference Jon, I am using Brembo aluminum calipers from an Alfa Romeo GTV-6 on the front of my 914. They bolt right up. On the rear, my friend Eric and another friend got together and cast copies of the ATE rear caliper. The weight is 4# less and the caliper gives up heat like it was never there. Once the 914 rear project is in production (and selling), we may work on making aluminum copies of the Sumitomo fronts. I got protested at an SCCA SOLOII event last year but it turns out the aluminum caliper is legal in SP as long as no modifications are made to mount them. I consider 2-3# of unsprung weight to be significant. There had better be a significant trade-off in another way. Anyway, my point is that people keep putting these things on street cars and calling it an upgrade. That is just wrong. I'd venture that most of the time it is a replacement for worn out stock brakes that would have been just fine in good repair.

Julio, I agree you didn't need it. You'd have been fine with stock + good performance pads. That is what I use for track days, I wouldn't for actual racing...

Sometimes I just want to scream when I hear the word 'upgrade' thrown around when it comes to cars. 'I upgraded my brakes with Toyota 4Runner calipers" GAG! No you didn't they're a hell of a lot more unsprung weight and you didn't change the rotor to a vented rotor to get the heat out. Now this is an upgrade!

A little more recent... Looks like Jeremy Dale? Cunningham Racing.
