Anyone have any experience with alu trailers? Would they be as durable as steel ones?

They can be, but to get them to be the same strength as a steel one they need to be made of quite heavier gauge material that negates a lot of the weight saving of the material. They will also suffer more from fatigue and electrolysis compared to steel as well, especially at the points were there is steel to alloy contact, or electrical current run.

lol classic.

yeah it tows good. had a flat already so need to ditch the rubber. :D

we had nothing but trouble until we changed to proper trailer tyres. haven't had a single tyre problem in the 3 years and 000s klms since

Another update, weve been doing a little bit on our trailer over the weekend, the final prep is very tedious and frustrating, cleaning all of the old paint and rust off.

We bought a new set of guards which werent too expensive, we reinforced the outer egde so they can take us 80-110kg guys jumping on and off of them.

The guards were fitted ontop of the side rails as we needed a little extra clearance for the tyres. We also fitted the 50x50mm tube for the front rail uprights, plus the extra second set for the wheel rack, which is 40x40mm and removable.

We also re-fitted the spare wheel holder, and made up the jerry can holder. We thought 2 cans are enough for the moment and if we need more we'll put one in front of each guard later on.

We bought some hinges and other stuff to make up the swining number plate which will also keep the second set of ramps from sliding out.

Now just to keep cleaning off the old paint from the checkplate and rails, then well give it a quick spray job :banana:

one tip. incorporate a way to lock down those jerry cans or some theiving asshole will pinch them and there goes $20 worth of can and $40 worth of fuel. :blink: well double that if they take both!

Haha yeah thanks, we thought about that, but we thought if were going to leave the trailer somewhere with the cans in it, well just put the cans in the car instead. Probably have to open the windows though!

well actually.....

in my experience people might be surprised how seriously some folks are with competitions, and how low they might sink. As a result I always lock jerry cans away overnight to ensure they are not "played" with. For the same reason I always check tyre pressures and wheel nuts if I've left the car at the track overnight.

this all started to sink in for me at my first race meeting - it was the last round of the year, and the champ leader (who was ahead by 1 point) had to pull in at the end of the warm up lap to have his wheel nuts tightened....

fatz wasn't one of his mechs was he? still remember being taken for a few laps of EC in Pete's R31, most of it sideways, then he goes "we gotta go into the pits to tighten the wheel nuts they get loose after a few laps". :(

Here are some pics of the trailer we have to tow my Silvia.

It was originally built for a 500kg clubman sports car we have but we have since modified it to fit the silvia.

Basically the wheels are inboard, not sticking out, meaning it is only about 6 foot wide, not really any wider than the tow car, it has no suspension, it runs quite tal light truck tyres, has disc brakes and weighs about 280kg with the spare whell and ramps, when weighed for rego was 260kg, but didnt have ramps or spare fitted. The axle is rated at 1500kg and the tyres have combined rating of 1700kg.

The car weighs 1130kg so all up it weighs about 1420kg ready to go. When towing we use stabiliser bars (which can be seen in the photos), and it tows very good, straight and stable, we have now done 4 trips from Coffs Harbour to Willowbank, and one to WSID for Compak attack with no issues.

The good thing about it is there is no need for a 4wd to tow it due to the low weight and the fact it is the same width of the tow car there is no need to worry about how wide it is.

Hope you guys like the tow car, for your interest it tows very well, also averages about 13l per 100km fuel economy while towing at 100kph.

We also tow it behind my dads new Xtrail with no issues.

can't see why a skyline can't tow either....99% the same chasis as stagea, same motor, same rear subframe etc.

not so sold on a single axle trailer for 1500kg but hey if you are happy and it works :P

how do you find the stabilisers? I've heard they are a good idea for big loads on IRS but have never seen or used them

The stabilsiers are great, my dad would not tow anything any distance without them.

Helps to keep the trailer tracking straight, and stops the rear of the car pitching, doesnt bounce up and down on the rear of the vehicle over undulations.

We have towed it without them behind my father inlaws 80 series cruiser and it swayed around a bit above about 95kph, with the bars on behind the skyline or xtrail it is great. Dad said he would have no issue doing 140kph or so with the trailer and car on behind the skyline it tows that good.

Would definately recommend some form of stabiliser bars regardless of the tow vehicle or size/type of trailer.

Which is why a twin axle is safer because the second axle prevents this.

Time to revive an old thread...

I've been considering selling my tandem car trailer and buying a proper enclosed trailer.

The type i've been looking at are known in the USA (ebay) as 'cargo trailers' where they sell for around au$4k in 14x6 sizes but here they go for around $12-15k.

Anybody had any experience importing a trailer from overseas, I realise that some things like lights, tyres may need to be changed to be registered however since the trailer is too big to fit into a shipping container the biggest worry at the moment is actually getting it here and the costs for that + duty and gst.

I saw in passing that DOTARS look after trailer imports as well as cars so maybe check the website. certainly trailers are still a place (one of the last) where you can "build it" yourself, get it engineered then registered.

If I remember you trailer is too small for most cars, if so resale will suck. It might be worth looking into enclosing what you already have....I bet the enclosing would be half the price of a new trailer.

Yeah mine is 13x6 where as standard width is 6'6 so once again in life im 6' short!

To enclose my current trailer would cost no more than $2500 however i'd much rather a new 15x6'6 chassis with drop axles and build it up from that which will cost $2800 for the bare chassis + about $2500 to enclose it.

The problem is I can't weld although my neighbour can and he is also retired so would just be a matter of drawing up some plans and paying him to do it (i've discussed it with him before). He isn't the worlds neatest welder but that is why i'd buy a chassis rather then get that made at home

    • With same diff ratio, tyre diameter and road speed, the tailshaft rpm is the same regardless of the gearbag's ratio. Given that very quick drag cars are probably doing similar road speeds to the fastest circuit cars (circa 300 km/h), and there will be many of either category that can't go that fast and so you'd have inummerable matchups between drag and circuit car speeds at smaller numbers, and given that they are probably using rather similar tyre diameters and probably using similar diff ratios, and...where any of those numbers were different they could quite easily be in opposite directions thus cancelling out.... I think you'd find that there'd be more similarity than difference in tailshaft speed between these two use cases, no?
    • they might see those prop shaft speeds for 1 to 2 secs only 
    • A year of slogging through this bearing issue and finally fixed. What a nightmare. The oil pressure increase did not fix the problem. If you would like to read all the details in case you ever run into a similar issue visit my thread on Yellow Bullet. https://www.yellowbullet.com/threads/continuous-rod-bearing-issues.2689569/?post_id=74193031&nested_view=1&sortby=oldest#post-74193031 In the end the rod bearings themselves were the issue. I had switched from ACL (first engine) to King because that was all we could get at the time and I thought nothing of it. Put the ACL's back in after a year of taking the pan off multiple times to change many things. Issue resolved. Can't believe it was just the bearings themselves all along. It has now been about two years since I drove the car on the street or had it at the track. At some point I had installed all solid and spherical bushings in the rear but had never aligned it since it just went on and off the dyno. Alignment was the first thing to do. (Old photo but same concept) Then I took the transmission out and went through it. This was my first gearset install and I've done about 15 since this one and learned a lot and wanted to apply some of these tweaks to mine. The aftermarket shift forks take very well to some modification and I wanted to make that change. Shifts are now super smooth and no having to find the gear. I also recut the 5th and reverse shift sleeves - always wanted to try this and see how well it works. It works very well! No grinds or having to do a second attempt going into reverse and 5th is perfect. Before During After Going back in In rummaging through my spare trans parts box I found the only parts I've ever broke on a stock trans; the 3-4 shift fork - twice!  
    • It also depends on gearbox ratio. Those drag cars running 7s passes aren't doing it on an overdrive gear ratio (probably). 1:1 is "fine", the critical RPM for a 50' single driveshaft in chromemoly is 6900rpm.... ....but when you shift into 5th and use 0:73 or 0:8 it all changes. Do you know their rear diff ratio? etc. That's the stuff that matters with regards to it. Whether it actually matters given your use application is also relevent. You may never get into those scenarios, like most ruined GTR's from Western Sydney don't :p
    • but for how long? would it handle a few laps around SMSP in anger?
