Anyone looking for some milling work?

 

Needs to be made from 6061 alloy, prob a 30 mm x 65 mm x 178 mm billet or larger.  More details / drawing on request.

Why bother when a similar thing is available off the shelf?

[grumpy xu1]

& it WOULD be engineered too, ask your insurance company there opinion. Front of hsv does similar thing to that c5 style.

[dattoman]

A commodore bracket is available off the shelf

Assuming your thinking CP5200 AP style calipers

But not a HQ/Torana style bracket

[Lima31]

If there is an off the shelf bracket to suit a LH torana with cp5200, I would like to know where ...

[dattoman]

Nope

Never made one or come across one

 

To suit 330mm disc ?

Theres a few kits around people have made for themselves... but they all use different stubs

Torana, HQ, CRS dropped

[Lima31]

Yes to suit a DBA 046, stock LH stubs and steering arms.

 

Would make it myself if I had the mill, the stock (and the time!)

[dattoman]

I usually make them out of wood

Trim and trial fit alot till they are right

Then take the sample to an engineer and price it up

 

Haven't had to do that for 10 yrs though... so not sure who could help locally.

[Lima31]

Yes I roughed it out with a wood sample, with the caliper clamped around a 2.5mm shim and the stub fixed in place.  I'm told I can get a prototype 3D printed in Asia for about the same price, delivered, as the router bit and the wood stock!

I'm going to try and mount leading side, too high up and perhaps hits UCA, too low and hits the steering tie rod.  On LH (at least my stubs) the caliper mounting holes are not level with each other, perhaps because one has to mount the dust shield.  Will need to include that in the bracket design rather than sit a washer in there.

Neil I was meaning the slightly tilted bracket, r8 vt - vz use c5 corvette style caliper standard fitment, then harrop, then ap racing was the top option around vz hsv. Gary

[dattoman]

Yep HSV used a few setups

All lug mount not radial

Then the AP.. but the AP bolted straight to the stub as it was a lug mounted caliper not a radial also

Just to clarify. If you want an adapter to mount AP or Brembo calipers that are radially mounted AND with a 152mm between the centres to bolt up to a stub axle that has 3.5" mount (just like HQ and Torana), then they are available off the shelf. Have been for years.

[dattoman]

And who has such brackets available ?

[Lima31]

I've been told UPC quoted "from $3500" for a kit to suit LH Torana

 

Hahaha no way you could trust that to fit first time given the reviews out there

[Uncle Chop Chop]

And who has such brackets available ?

ewww...wilwood

[Lima31]

Thanks for the suggestion although I think that particular bracket is too short radially for a 330 mm disc (instead of 28.9 mm should be around 45 mm), and the axial offset is out by like 5 mm (instead of 6.6 mm should less than 2 mm).

[Uncle Chop Chop]

ewww...wilwood

 

Have you used them?
 

[dattoman]

Not those actual brackets

But I have in a past life used wilwood products

 

Or better yet... removed and thrown in the bin wilwood products and fitted better stuff

 

For budget gear and visual wank they are ok for some applications

But I personally wouldn't use their products

[Uncle Chop Chop]

But those brackets may be fine and if nothing else could be used for a test fitment to get a "proper" bracket made? I think it would be better to get a bracket made using that as a sample, as you would then know what fine tuning would be needed. It wood be more expensive than your block of wood method, but a lot quicker.

[Uncle Chop Chop]

Out of curiosity Neil, what is your preferred metal for making caliper adapters with?

[dattoman]

Just stick with the light weight balsa

 

6061 or 7075 if the guys got lots of money

[Bigfella237]

Damn, why don't they make a 3D Printer that squirts molten alloy?

[mick_in_oz]

You can do something akin to Powdered Titanium from a 3D printer...
