Every police officer and vehicle inspector in the country knows that spacers are illegal in all States unless they are supplied by the vehicle manufacturer. Porsche fit them to some of their cars.

I've just listed my dash on ebay - pretty sure it's a 260Z. I will be in Canberra at the end of the month and could deliver if anyone there is interesred. http://cgi.ebay.com.au/Datsun-Dash-Gauges-260Z-240z_W0QQitemZ320315613202QQcmdZViewItem?hash=item320315613202&_trksid=p3286.c0.m14&_trkparms=66%3A2%7C65%3A1%7C39%3A1%7C240%3A1318

A couple of thoughts: Wosa - considering jerryb's interest have you considered doing a writeup of this on HybridZ as a means of generating more orders. Plenty of its member have the Wilwood setup so they will already have the hats, rotors or main calipers. You might consider doing a full writeup (photos, etc) in the 'brakes' forum and then seek orders in the 'group buy' forum - include cross-referencing. Remind them how good their exchange rate is. Gee, I can remember saying that about us just three months ago! Also - could others who have posted on this thread consider modifying or deleting posts which are not relevant. PA

I have a complete 260Z dash and a complete 240Z dash that I no longer need. They have all the instruments fitted and I think the wiring is still in both. I have no idea what they are worth so the fairest thing to do would be to put them on eBay. I will try to have the 260 posted next Sunday for a week.

With the present perilous exchange rate you might be better off considering a local product (fronts and back) http://www.k-mac.com.au/ (click on "New Products" and then on "Datsun") I assume from their advertising that the items are street legal.

This design for the parking brake is not an original idea - and Wosa doesn't claim otherwise. It is just that he is applying it to the S30. It has been used on many modified and ICVs particularly in the US, UK and also in Australia. They can be purchased off-the-shelf for other vehicles. If the concept has already passed engineering certification here in Oz several times I don't see there will be any capability issues. I have every confidence in the product.

Woza - Count me in. That's only $250 per side which is the same cost as three tanks of petrol. If the car is off the road for three weeks while I fit the brakes I will save that much in petrol - any longer and I am making money. That's how I explained it to my wife and she agreed! One question - are the brackets aluminium or steel?

Here's mine. As you can see, just a few minor things still to be done!

Do some proper research and stop listening to and perpetuating urban myths. ADR stands for AUSTRALIAN Design Rules, not NSW Design Rules. ADR apply in all States. The term 'dust seal' is never mention in the ADR, it only state that "...the braking equipment shall be so designed, constructed and fitted as to be able to resist the corroding and ageing phenomena." I have spoken directly to the engineers at the RTA (not gone on some BS hearsay) and they have no problems with seal-less calipers. I suggest you get an engineer who is better informed and doesn't over-interpret the requirements. Finally. Not having dust seals is not an issue as long as you clean up the exposed piston surface before you press the piston back into the caliper when fitting new pads. If I wanted to pick an issue with a self-opinionated engineer I would argue that seals are prone to 'ageing phenomena' and fitting seals would be contrary to the ADRs - Let them argue that!

Wosa - you might try a ship chandler - plenty around Fremantle from what I hear!

The way I understand it, the AZC hats are the Wilwood hats - the same way many of his other items come from this supplier, http://www.nosms.com (I've bought parts direct from them). Dave is something of a middle man with some items. That's not a criticism, in fact he does a great job bringing it all together where you know everything matches up.

Not so. They are a Wilwood stock item, #170-1754

Why not just buy all the rear components from Wilwood and save yourself the cost of the unwanted AZC bracket?

My apologies Chuck. I misread your request and thought you were after the catalogue number of the main rear calipers. I can confirm the number of the parking brake calipers are 120-2281 & 120-2280. Damn ... these senior moments are getting more and more frequent!

The rear calipers I got from AZC are both #120-8606. You might get lower prices at other suppliers but it will probably be cheaper all up if you just get one package posted from the AZC. To my knowledge there is no such thing as seafreight these days for items like this, it's all airfreight. I paid around $350 about 12 months ago but fuel has gone up a bit since then so it might be higher.

To answer some of my own questions I have gleaned the following information over the past few days. The Wilwood 'rally' Powerlite 4 spot caliper does appear to incorporate a PARKING brake. http://k80rum.co.uk/Mechanical_Handbrake.aspx The calipers and cable are around $600AUS before shipping. The Powerlite caliper is radial mounted as opposed to the lug mounted style on the AZC kit's Wilwood Billet Dynalite, as the regulations allow only one mounting bracket they could not be adapted to the AZC brackets, you would have to manufacture your own mounting bracket from go. Also, the non-handbrake Powerlites in the Wilwood catalogue indicate their fitment on rotors only up to 11" - the AZC kit rotors are 12.2". I don't know if that will create problems but I personally don't want to spend $600 to find out. I'm going with Woza. Whenever I enquire about Wilwoods everybody mentions that vehicles fitted with Wilwood calipers without piston seals cannot be certified in Australia. I read the ADR on brakes and all it states is the components should be able to resist corrosion, I would surmise the dust seals might prevent wear and scoring on poorly maintained vehicles but would not be a significant factor in preventing corrosion. I spoke with the engineers at the RTA today and they have never heard of seal-less calipers being unsuitable and there are no regulations related to it. Sure it might aid longevity but being careful when you change pads that you cleaned the exposed piston before pushing them back into the caliper body would achieve the same outcome. Come on guys/gals, order up big on Woza's bracket and the price will be lower. Remind your partner that it's Fathers Day on Sunday. Note: I have no association either privately or professionally with Woza.

I'm thinking these calipers may be limited to active rallying manoeuvres (Scandinavian flick turns, etc.) and perhaps not for long duration parking applications. If the actuation mechanism is as supposed by woza and there is only one pull-point on the hook device (assumption), couldn't the edge of the pad in contact with the outer most portion of the rotor act as a pivot causing the pad to apply an equal and opposite reaction force on the piston and SLOWLY force it back into the caliper. The same way you force old pads off the rotor when you are replacing them. If I'm right (not a given) wouldn't the initial handbrake force applied by the pad or at least the area in contact with the rotor diminish after a relatively short time. Again, if this is so and the piston is forced back, what happen first time you apply the brakes after parking the car with the handbrake applied. I'm guessing it will all depends on how evenly those hook pieces apply the pressure to the pads.

Yep, you're right, guess I didn't look hard enough. Here are the calipers http://www.rallydesign.co.uk/popup_image.php?pID=11370 and here is the cable. http://www.rallydesign.co.uk/popup_image.php?pID=13239 Thanks NZeder

Are you sure these are not for the hydraulic handbrake setup, i.e. rallying application? They don't look mechanical to me. The only mechanical combination handbrake/rotorbrake I can find is the one cylinder (floating) example shown in my previous post.

Just a point about the Wilwoods with the built-in handbrake (see image) - make sure you will have rim clearance. I am only running 15" and there was no way those calipers would fit, that why I went for the two separate rear calipers, plus the fact the 4 spot rears look fantastic. Woza in on an absolute winner with his design. If you are buying the Wilwoods then Dave at Arizona Z can source the handbrake caliper for you - saves a separate freight charge. That's not an ad for him it's just that he was the cheapest supplier I found. Wilwood don't appear to list the Mechanical Spot Caliper on their site now they have the built-in unit but the units are available according to Jegs etc., and as I stated from Arizona Z. http://www.wilwood.com/Products/001-Calipers/033-cpb/index.asp

I'm installing an LS1. It passes the National Code of Practice requirements to which NSW will eventually sign up.

Thanks - I covered the unibody construction. I can see where your engineer and the regulators are coming from on this. Changing the configuration, even the gauge size of components, will affect the deformation pattern of the vehicle in an impact. From that perspective I would agree that careful consideration needs to be given to replacing the engine bay rails with a heavier gauge material - the last thing you want on impact is for them not deforming but coming through the firewall into the occupant compartment. I don't think an S30 would have any ADR compliance requirement regarding cabin intrusion other than the side intrustion bars in the doors - anyway the steering wheel is likely to kill you before anything else. I doubt any modification which strengthens the occupant compartment would likely be rejected on a car of the S30 vintage. The lastest update has NSW adopting the National Standards in Jan 2009, i.e. three years after the other states!

I contacted the RTA today and was advised that there is ... how shall I put this ... 'a significant degree of inexactitude' in this statement. PS. Thanks for the sleepless night! PPS. I note your edit and I actually do appreciate your post, it made me double check the situation.

As Pauline would say "Please explain!" I would be interested in the background to this statement and any relevant references you have. I have just had a set of full-length, deeper and heavier-gauge rails made up (copies of the US Bad Dog design) and was planning to install them next week. http://www.baddogparts.com/
