Im currently looking at a brake upgrade for my LX hatch and are going to fit a UC crossmember, but I want to keep standard stub axles and track to remain standard width.

Had Hoppers in mind but called them and they tell me their brake upgrade kit will push the track out 8mm per side.

With the wheels I'm running, (15 x 8 Superlites) that's not gonna work, they are close to guard lip already.

What are other brake upgrade options keeping standard track?

Datto??

Add an extra degree of neg camber

 

I thought Hop's had a 0 offset kit nowdays

[TORLX8]

Yeah I thought they did too Datto, but they reckon they need extra 8 mm per side so calipers clear uca.
So just 1 degree of neg camber would be enough to keep top of tyres under guards you think? Won't create too much uneven tyre wear?

[neglectedtorana]

McDonald Bros have what looks like a good HQ kit using Wilwood callers, they could probably make you one in Torana pcd

I don't know but think offset would be the same as std

Add an extra degree of neg camber

 

Wheel track is measured from the centre of one tyre to the centre of the other at the point where the tyres contact the road, adding NEGATIVE camber would INCREASE the track measurement (tilting the top of the wheel inward means also tilting the bottom outward).

Thanks Neglected. I also found some Wilwoods that reduce track by 1.6mm per side and in Torana pattern.  http://www.pro9.com.....php?PCID=10724

I know there has been some discussion on here about Wilwoods not being legal for road use but it says these ones Engineer approved. I guess that means they're ok for road use?

 

That makes sense Bigfella. Thanks. So having wide wheels and tyres is not going to keep standard track either.

 Maybe I should've been more specific and said standard width brake hub to brake hub?

 

[dattoman]

I thought you were just trying to get the wheels away from the guard... hence my glib remark about laying the tyres in abit for clearance

I know the track is still different... but I don't think you give a flying about that (for rego purposes) just to keep the tyre from the guard... right ?

[TORLX8]

Yes absolutely correct there Datto.
What do you think about those particular wilwoods in the link in my previous post?
I realise you must get thousands of brake questions directed at you so I appreciate the input.

[TORLX8]

That's the BW1100LH ones I'm referring to.☺

As I understand it, the older Wilwood calipers did not have dust seals and so did not meet the requirements of the Australian Design Rules (ADR), as such they were sold "for off-road use only" (as so many things are).

 

Apparently the newer stuff does have dust seals and I have seen many Wilwood setups approved by various engineers.

 

So having wide wheels and tyres is not going to keep standard track either.

 Maybe I should've been more specific and said standard width brake hub to brake hub?

 

Sorry, I misunderstood your original post, it sounded like you were concerned with the actual track measurement not simply tyre to guard clearance.

[dattoman]

Those calipers appear to have a black ring around the piston

So appears they have a dust boot

 

The issue I have with Wilwood and similar cheap US caliper is flex

They have a spacer put between the halves to make them suit a vented disc... and only 4 little bolts holding the caliper together

So in my mind they may be prone to flexing under pressure

Not to mention the small pads...and the stupid 1/8" -27 tapered fitting

 

Unfortunatly most better quality (European) calipers are much larger and are difficult to fit in the space provided

[neglectedtorana]

Engineer has approved the Wilwood callers I am using

Those BE1100LH is pretty expensive compared to the McDonald Bros kit

Agree with Datto the 1/8 npt threads are annoying to deal with and find the correct fittings but I got mine connected and bled on the weekend

[TORLX8]

Think I will steer clear of Wilwoods after reading the info you guys have posted. I see McDonald Bros also have a PBR kit which might be worth contacting them about. Hopefully they are same as Torana width.

[Uncle Chop Chop]

Wheel track is measured from the centre of one tyre to the centre of the other at the point where the tyres contact the road, adding NEGATIVE camber would INCREASE the track measurement (tilting the top of the wheel inward means also tilting the bottom outward).

 

If you use pythagorus theorum, 1 degree change would only alter track by a few mm.

[LS1LX]

Can you machine the hub of the wheel to bring it in? Is the hub thick enough for machining like hotwires

[ozyozyozy]

Agree with datto, the pad size on the wilwoods is not there.
The wilwood 6 piston calipers i have seen use a smaller pad than the ap racing 4 piston.

[TORLX8]

Well I contacted McDonald Bros about PBR kit and that also pushes hub out 5 to 10mm.

Plenty of meat on wheel hub for machining but wheel is already very close to UCA.

Found these on fleabay.

 

The writeup sounds good, but what do you guys reckon?

[neglectedtorana]

Don't know anything about them but pretty sure Rare Spares stock those Baer brakes, have seen them in the display in the Sydney store

[TORLX8]

Has anyone tried this Baer brake upgrade kit?

[rexy]

Well I contacted McDonald Bros about PBR kit and that also pushes hub out 5 to 10mm.
Plenty of meat on wheel hub for machining but wheel is already very close to UCA.

By machining the hub to adjust for the extra width of the brakes the wheel should maintain the same relationship with the UCA as it does now.
Go for it.

[TORLX8]

Shit you're right there Rexy. What was I thinking??
Great pickup. Thanks.

[rexy]

If it was me I would fit up your new stuff and see how close things are before I got the wheels altered.
The hoppers and UPC stuff is much the same. Nice polished or painted calipers would look good.

[TORLX8]

Yeah the rears already have 8mm off hub, so will be perfect for trial fitting for fronts.
Yet to decide on caliper colour or to polish.

[Bigfella237]

By coincidence I noticed the other day that Wilwood are now offering their calipers in a choice of 24 colours (or "colors" if you're American)...
