289 progress........

[1985 CCX]

A stock Ford unit resides on Goldie at the moment....

[PDUB]

Nice, Jeff! Great addition...

[1985 CCX]

Another small detail, these are original

[1985 CCX]

And winter begins.
Added the upper rear panel with a step for easier install and removal.
Made by PanelCraft install and fit 😄

Now
Next: Girling installed race brakes.
Starting with front then rears.

[1985 CCX]

Girling CR up front.......
Girling ORA rears.......

Using BG rotors, very nice pieces.
I’ll post step by step as I begin next weekend.
Already want to thank Jim for his insight, Craig for ORA’s, Ross for the bracket and Cobra Automotive (Curt and Paul) for help with rebuilds and tips.

Will be a nice upgrade

Jeff,

No problem. Looking forward to seeing everything come together.

Jeff What uprights do you have? I would have thought yours would be a straight bolt on like an original . I have rotors from Tom Petrus. They also seem to be of very good quality. I also got new Girling Cr and Ora's from Crosthwaite and Gardiner. I think all my stuff will bolt on like an original with no drilling ,tapping , and no extra brackets.

Post plenty of picture of your install.

[1985 CCX]

I'll post step by step as I progress forward.
Direct bolt on the rear, fronts use a bracket however I am not that far yet.
I am also told there were slight differences in the originals so that too may require a few head scratch's.
My uprights were HiTech 289 units as I recall. (Never sure though as stuff is always passed around)
Either way I'll get them on as I have lots of Cobra assembly "make it fit experience".

Starting this weekend.... Brace yourself for TMI

[1985 CCX]

So tomorrow will be the day we start. I assume since I have the Shelby calipers that I have the separate steering arm / caliper bracket.
Could be wrong so we will see.
Planning fronts first then tackle the rears.
Awaiting rebuilt CR’s from Cobra Automotive.
Will post pics soon.

Here is what we hope is there........

Ross Henry

Thank you for the Brackets if that is the direction I take forward.

[1985 CCX]

Ok, today was a tear apart and figure out direction.
BG Rotors are ready for fitment, thank you Cobra Automotive.
Initial set up is a modern rotor and PBR calipers.
All to be removed.

Once apart it’s clear that there are two options either original steering arm or use brackets supplied by Ross.
Caliper alignment may dictate this decision.
Calipers still at Cobra Automotive getting new seals.

[1795]

Jeff,

Yes, those are the options. That's why Ross, Rick and I came up with those brackets. You still may need some small washers to shim things, but they should be pretty close.

Nice looking rotors look just like mine with one small difference.



Looking forward to seeing things come together.

So the surface area comparison favors the old school units and the venting along with diameter favors the new.
Pins are same thread. Phew...... ��
Assembly is easy however I need calipers for determination of caliper alignment. Nothing rubbing which also made my day.
So far so good, once I have a plan I’ll paint areas of untreated metal to avoid rust, clean surrounding area and make for better operation.

[MAStuart]

Jeff looks like you have uprights and hubs from George. It will surprise me if the adaptor brackets will work for you. They made them for the super performance. Anyhow I took a picture with a measurement. It might be helpful to see if the brackets will come close. The surface where the caliper mounts against bracket is 1 1/8 inches. In the picture the caliper is centered over the disk . The rule is against the disk and to the mounting surface of the caliper. This surface is that goes against the mounting bracket. If you can use the bracket. The mounting bracket goes between the rotor and the 1 1/8 mark and the bolt comes in from side by the 2 inch mark.

[1985 CCX]

Picture is a little dark for me to see?? I do know that Paul at Cobra Automotive found some arms for me and they do match the calipers at the attachment point. So the question, what will be the best way to get the caliper centered on the rotor for best performance and equal clamping power.

Will need parts in hand first so I can identify best direction for me to take.

Nice looking steering arms Jeff! Question; they look to be straight like the standard street steering arm. Will they need to have a bend to accommodate larger tires and alloy wheels?

Great question as I do run Mag 6.5" with Goodyear Powercushions.
The units I have now are ever slightly bend, all fits as it's on the rim where tire width is outside that area.

Will post all exciting details as they arise....

[MAStuart]

Jeff for some reason the flash would not go off. Replaced the picture with a little better one.

The steering arm they show with your calipers look like they from George or his son. I have a set. I believe they are an investment casting of some type of stainless steel. If you do not have to bend them, they should be a bolt on deal. I think they told me to bend them, they will need to be heated cherry red. I am not sure on how they should be cooled. You would need to talk so someone that knows about those things. That being said parts of the arm is hollow. To me its a casting flaw. Tom told me all of them they have are like that . In some of the pictures below you can see the void in the bolt hole and where the tie rod goes in.






The arms are right and left handed. The single one above them is an unmachined forging. They can be machined to be right or left handed.

[MAStuart]

I had to go out and get some bolts to mock these parts up. I have had them for some time now, and have never put them together to see how thing would line up.

I was going to tell you the rotor does not have to be centered perfectly. The two pistons in the caliper will move the pads out touch and the fluid pressure will equalize and the pistons will be pushing against each other.


Overall shot of the assembly


Picture shows how rotor is aligned in caliper


With this picture you should be able to put your wheel on, and get an idea if you wil have o bend the steering arm to clear the wheel.


Another shot of how thing align

[MAStuart]

One more picture of the way the arm bolts to the upright. In this picture you can see the bolt hole with the threads. You will notice part of the hole has no threads. This is done so that when you have the right bolt part of the unthreaded shank of the bolt goes in there to align the caliper an hold it tight and to help to keep the bolts from shearing off. This bunch of picture should give you an idea of your install.
