Has anyone made/used a car trailer with independant suspension - using a al-ko/avonride type pre-fabricated trailing arm system...

like these:

Im about to build my own 2000kg car trailer, im thinking about giving them a go to get the trailer lower, lighter and smoother towing.

we havea camper trailer that uses that style suspension - seems to work well with a 750kg trailer.

you'd need to get the load rating for the setup though as the rubber inserts might need to be a different density for towing a car.

where are you looking to get the setups from?

It seems to be mostly Qld based mobs that handle them...

I have to ring them and get more details, but from what i can work out the smallest braked axle set is 1100kg, and the largest un-braked is 900. Which I guess means if you get one of each you can only really run 1800kg on it, or you have to go for a pair of 1100kg ones and have all 4 wheels braking - which probably isn't a bad thing.

I'm yet to find out how expencive they are, if the get a bit rediculous I might have to go with drop axles with leaf springs instead.

They seem to be hard things to get, cant find anyone in adelaide that deals in them.

Vehicle Components in QLD don't handle them any more.

Found one online shop that has them - about $2000 for a pair of 1000kg axles with 10" electric brakes on one axle.

I have found a local supplier, they need to ring up the factory and get a price for me, but they seem to be fairly reasonable.

Hopefully they will also save a lot of weight, solid 45mm axles seem such a waste of steel when slightly larger but hollow axle would be half the weight and a whole lot stronger.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
