you just use torana ones,the hq-z are two inches(exageration) too long

so you lose half your turning circle

And they are also too high where the tie rod end is positioned so you get terrible bumpsteer if you use any of the HQ to HZ series steering arms on a Torana.

[fuzzypumper]

Toranamatt69, your basically saying I have to spend $300 on A9X steering arms from HArrop to stop the caliper from fouling and correct the turning circle and bump stop issue ?

If so were do I get them from?

[dattoman]

Harrop arms won't clear the caliper....... it still needs grinding
They are recommended if your using HQ stubs on a Torana ...... you can use the Torana arms as alot do ...... but may encounter bump steer issues
Depends how lowered it is too
Till its all bolted up and you can see the angles of the rack ends you won't know I guess

And you'd buy Harrop arms from...... um Harrop I guess

[arrimar]

why go to all the bother of grinding etc when a hq caliper will bolt straight on with a hq-z stub? if your after great brakes ,go for something exotic. if you want to use standard equipment then use something that fits.
here is what i wanted to replicate.

L34 pbr caliper.


this is what i had.
standard torana pbr caliper.
remove and throw away,remove stub and throw away.


this is what i did.
HQ pbr caliper.
put left hand hq stub on right hand side of car,fit UC steering arm,fit disc and caliper.
repeat for opposite side.
route hoses in a safe manner(ignore pic/not finished)
ensure caliper doesnt foul upper control arm.(some arms need a clean up of lower edge.)


now thats not rocket science is it?

[fuzzypumper]

So why HQ calipers as opposed to HZ or better WB alloy ones? Is there a clearance issue with the later calipers on steering arm, control arm or brake line positioning ?

Also why use a HQ stub as opposed to a HZ stub? I believe one lowers front by an inch , but which is which? Considering I will be increasing rim size to 14" I suppose the difference will be only half an inch.
Currently my car is only lowered slighty and my tie rod arms are perfectly horizontal.

Azureblueslr said "these are a must have in my oppinion regardless of cost (i dont think there that expensive anyway ) ".
These A9X arms might be a must in the end but in my opinion $300 is a bit much for 2 pieces of steel with 3 holes in them.

HQ calipers are a more rigid design and have a much better selection of pads available, the down side is they are heavy.
The later HZ alloy ones flex heaps and wear on the slide pin bores which are both undesirable - I'm not sure what the WB used.... Datto your turn

All the HQ through to HZ stubs will give you a 30mm drop and are essentially the same.

I have driven my car around using both UC and the A9X steering arms and the difference is quite noticable and I have also measured the bumpsteer and it supports what I felt when driving it - I would spend the $300.

$300 is a bit steep but that is called supply and demand (AKA extortion) - I am just happy someone makes them, would be hard to pry them from the A9X buggers these days - you could get solid gold ones for the price those cars' parts go for.

Perhaps a better option is to get a hoppers kit and use your Torana steering arms and stub axles and end up with even better brakes whilst maintaining reasondable bumpsteer?

Go back and read this tread from the start. There are some very informative pictures there as well.

[fuzzypumper]

Yes Sorry ALX76, Im repeating issues.

Well I suppose at $300 for the A9X arms plus another $300 for Pins, calipers & discs , its till approx half the price off a hoppers kit @ $1200.
However by the time you add the fact that you need new rims & tyres due to the stud pattern change it may get up there again.

Does anyone know what stud pattern the hoppers kit is and what model disc it uses?

@ $1200 they will give you any stud pattern you like.
your 13" wheels won't clear any of the mentioned upgrades,
as for any other questions about the hoppers kit maybe ask this guy http://www.gmh-toran...?showtopic=7766

[antelopeslr5000]

You can find the arms here.

[REDA9X]

good to see you here Joe.

[micklx]

How much more grinding to the caliper bracket is needed if UC steering arms are used instead of A9X (Harrop)arms ?

[antelopeslr5000]

A9X Caliper.

[Torryhead]

hey pal, i know this is an old post but hopefully you have it tagged. i have been reading through what you blokes have been saying about the A9X stubs but none of the pics work for some reason. was wondering if you could post them again or send them to me. thanks mate. i'm looking into lowering my car an inch and different stubs seems to be the best way

Dan

hi all
Im back from my holidays at tassie, and are back into the torana. Shouldnt be long before she rolling again.

Sorry YiriSS, but im on the central coast ( between newcastle and sydney about 4 hours from coffs harbour ) not sure if youll be down this far but pm me for more info.

As promissed here are the rest of the shots from the conversion

thats all for now. If anyone needs anymore info get in touch with me.
cheers julian

[76lxhatch]

would you have to take too much material off the caliper?

To fit the alloy Girlock with Torana steering arms, probably yes
