C5 template/ drawing

[Olav]

Anyone having a draving or a template of the brackets for mounting C5 calipers to Camaro 2-gen spindle.

Thanks!

Hej Guys, I am also looking for a drawing to make brackets for a C5 caliper for a 68 Camaro drum spindle.

what steel/aluminium do you guys recommend?

I used the bracket template and it worked out great. Heres some pics;

Ack -- is there really that much space between the wheel studs and the rotor holes? I'm pondering the LS1 brake upgrade, but I'm not a big fan of havin 1/8" of backlash between the wheel studs and the rotor. Almost looks like 7/16 studs with 5/8 holes. Nicer brakes though.

I've noticed that with production cars - my Intrgiue, for example. Impact?

Also poke around nastyz28 (http://www.nastyz28.com/forum/forumdisplay.php?f=17). There are a bunch of guys who have done this.

The 98-02 12" LS1 rotor has a 5 x 118mm [5 x 4.646"] bolt circle and oversize holes so that they can be used on multiple non-domestic applications with differing bolt circles such as the 5 x 120.65mm [5 x 4.75] pattern used on the F-body.

If you're using your wheel studs in shear to keep your rotors from spinning, you may want to tighten your lug nuts. If your wheels are properly torqued, your rotors should never move between the hub/wheel interface.

This template is for first gen. Anyone having 2-gen brakets and kan draw a line around them on a paper... Or a link to a template....

Olav,

If you decide to go the LS1 route I do have templetes drawn up for them. I think I even have a .jpg of them at home. Only issue is that they are really tight; the caliper bracket bolts are tricky to get in. Not a greate angle, but this thread has a pic of what mine look like: https://www.pro-touring.com/forum/showthread.php?t=22131&highlight=skunk

I have the C5 calipers and rotors. Not the LS .... The drawings you have will they fit?

Thanks

Hmm, the calipers are interchangable I believe, but the C5 caliper bracket uses 14mm bolts, where as the LS setup uses 12mm. Not sure of the spacing between bolt holes. Mine is not fancy or pretty, but it works. I a strip of 2" wide 1/4' steel for the bracket.

Don't the washers give it a custom look? :naughty:

I found my templete, but looks like the mice got to it a bit. Here are the dementions:

5" between caliper bracket holes
7 5/8" between spindle holes
The two holes for the caliper bracket were centered between the spindle holes and 11/32" below them.

Makes a bit more sense if you look at the photos above. BTW, I drilled out and retapped my spindle mounting holes. Can't remember, but think I resized them to 7/16". Hope that helps.

Thanks! I will measure later today after work. I will probably make the brackets of 5/8" plate ( on Core3's site it says 5/8") so I dont need the washers.

I assume you are talking about using aluminum? That would be a heavy chunk of steel :razz:

[Olav]

Took the measurements they are the same. If I make them of steel I have to mill them to get them as light as possible. Don,t like alu for these parts. Are your rotors 13" ?

Thanks!

[Olav]

Plate is 1/2" 0.77kg/1.69lb not 5/8"

Olav

[barno68]

No, the LS1 rotors are 12". If the measurements on the basket are the same, just drill and tap the holes to 14mm instead of 12mm and raise their location 1/2". Actually, I think that extra 1/2" will make it a much easier fit than the LS1 setup. It was real difficult to get my big mits in there, felt like I was working on an import!

Are you buying aftermarket hubs or just cutting off your stock discs to make a hub? I did the latter and it came you nice.

Brent

[70TWO NOVA]

I used front drum hubs, just machined down slightly. Works great too.

[Olav]

Found a picture on kore3 site and did some measurements. Found that I had to raise the holes. I will make my own hubs when I get a used pair of 3-gen brake rotors.Did you use 2-gen rotors ? They are hard to find in Norway and new one costs about $100 each here. I work as a mechanichal supervisor in a ship yard so machining is no problem.

Thanks!
Olav

[barno68]

Yep, my car had front discs already, so just used the old ones. $100 is steap, you could just about buy the hubs Kore makes for that. Did not realize that the 3rd get had the same bearing sizes.

Brent

I think I may have a pic or two for you... I'll check for some info.

Made the brackets of 12mm plate. The brackets that are sold from various suppliers are of 1/2" plate 12.7mm. The diffrence is only 0.7mm, BUT the abutment is not 0,7mm out of center its 3mm/1/4"? I will make som shims in lathe and TIG Weld them to the bracket to center them.
Are the abutments out of center on the bought adapters also?

Olav

[cdoggy81]

Wouldn't these from Kore3 or Eng. Vel. work also?

[86Cutlass383SR]

I hope I'm not stepping on any suppliers toes or whatever....

That being said, I have a template for the second gen/ b-body spindle for the C5 calpiers. I was getting ready to mail it out to someone who earlier requested it from me. I can photocopy it on a piece of paper to anyone who PM's me there mailing address. Mine are identical to the aluminum brackets in the above picture.

I also, if I can find them, have the C5 template for the 1st gen spindle. I can also make a template of it if anyone want's it. Same procedure, PM me with address and also let me know which spindle bracket you need.

I bought both my brackets and have not yet installed them so I can't vouch for the accuracy. Slight shimming and/or adjustment may be required.

If any suppliers request that I cease sending these templates, I will. As I said, I'm not trying to step on any toes, just trying to help out fellow gearheads upgrade their brakes.

These will work, but I'm working as as mechanichal supervisor at a ship yard so it was not a big job to make these.
But as I wrote. Is it required to shim to get them centered? Not a big problem, but since the brakets from Core and others are only 0.7mm thicker and I dont know if they reguire shims.

Olav :drive2:

[matty b]

the kore3 brackets are really nice and bolt right up. For the price its really not worth the time to make these. Not only that but they also come with all the hardware and a very detailed instruction manual for installing them. I understand the DIY approach people have but I dont think its really worth the hassle in this case to make them at home. good luck which ever way you go

[Olav]

If I was living in US I also would have bought them from Core or any other company. BUT the shipping cost on these are the same as the cost of the brackets....
The the downside of living in Norway and playing with US Cars....

Cool! Every bit helps. PM sent :)

I still wonder if a guy could use the 1LE 12" rotor and not need a separate hub/rotor and have a better wheel clearance offset also and have a bracket for that.

C5 caliper and 12" 1LE, should be possible.

I slid a 04 GTO caliper(same general dimensions as a C5 just a different basket/bracket) on a 1LE rotor and it fit fine in the 15x8 Trans Am Snowflake wheel.

Cool, got any pics?
