Dear torana friends,

does anyone know if its possible to use front spindles from american cars from the 70s like the Camaro,Firebird,Mustang or other at the Torana LH control arms?

Camaro uses the same ball joints
1967-69 at least

But why would you ?
They had worse brakes than ours ... haha

Willwood sales disc brake kits with billet alloy wheel hubs in all different stages for this cars.

Now to find out if this spindles higher or lower than the original Holden ones.

I did see aftermarket spindles in a lower version for us cars.

By now we are about to built own billet wheel hubs to use vented ford brake disc 300mm diameter front and 280 mm vented disc from a Renault for the rear .

Good luck with that, let us know if you find something that fits.

HQ are basically identical rails (albeit RHD) to 2nd gen Camaro. So maybe the stubs are similar? Find a 1970.5 onwards Camaro and have a look!

[dattoman]

Just make a hub and caliper adaptor bracket to suit your original spindle
And stay away from wilwood
Your in Germany... AP or Brembo should be your first choices

I always thought Wilwood made good brakes... Not the case Dattoman? Whats wrong with them?

[dattoman]

Generally speaking... cheap US trash
Poor casting techniques , prone to flexing , no dust boots ,pads are hard to get here , 20mm thick pads squirm on the backing plates when hot ... etc etc
They have certainly improved... but... the guys in Germany... theres so much more he could do than slap on something very average and try to go racing
The amount of AP and Brembo stuff he could lay his hands on off say... old Porsches... would be staggering
Depending on his wheels... a set of Big Reds or even 928 S4 calipers would be an enormous improvement over any off the shelf Wilwood caliper
Lotus Brembos... they work well on Toranas too with suitable brackets and 300-330mm discs (depending on wheels)

I say adapt something to the spindles you already have
Changing the stubs will lead to suspension and steering issues that will have you chasing your tail for years trying to sort out

[The German]

Yes

Dattoman can be right with the Wilwood quality, i know there is not much Wilwood here in Germany and i dont know how good Wilwood is in US Motorsports.

I had a 4 Piston rear caliper in my hands and i can say its realy light and you as a customer has to choose the options what should be inside of the caliper,if you choose aluminium pistons (for low and mid temperatures) they will die soon at races.

Wilwood has calipers with rubber seals for the pistons as i could see are available. Also stainless steel and titanium piston calipers for extreme temperatures.

I think it is like everywhere ,good money,good quality.

But as i said,i have no other Willwood informations from a driver here at my place.

I try to find out a light weight lower front hub solution for this 108mm bolt diameter.

Otherwise we go to a 120mm bolt diameter (BMW) to get more options with wheels later on.

We about to build a AP disc brake system in the German classic way, to use existing aftermarket discs.

I did see a Mustang II spindles wich looks like the Holden ones and this Mustang II spindle has maybe a lot aftermarket solutions.

Exploring is fun....

........what about having HOOTERS Cologne on my car as sponsor?


Uwe

[dattoman]

Well if it was me.....


I'd start with making a billet hub ... use 6061 or 7076 grade alloy treated to T6 hardness (don't go making it off my picture then say it doesn't fit... check your own work)








Then buy a pair of CP5200 calipers from AP Racing



Then a pair of 330mm discs to suit... 28mm thick
Commodore discs are 83mm top to bottom measurement and pull the caliper back nicely from the wheel face just as an example
I'd do these 2 piece and have an alloy hat (using your own measurements )



Then make a billet adaptor bracket to mount calipers also from 6061 or 7076

Should end up looking abit like this when front mounted onto a Torana (I think this has CRS 2" drop stubs)



Then check your wheels for clearance



Wunderbar .............

Should keep you busy for awhile

Anything else you need ????????

Sweet !

....keep me busy.

Thats this moments when i do belief the reason for a Forum.
