On my quest to find some rear porsche stub axles, a friend has given me some porsche aluminum trailing arms with discs !
So do I strip them to get the stub axles, or should I use the whole trailing arm ?
Is this easy to do ?
Can you fit T3 drums instead of using the disks?
Are they strong, they look it ?
Any advice would be good !
Its to be used on my buggy with the Kombi box :thumb
Do you have any pics. If they are simmilar to vw ones I would try to modify them to fit and then polish them they would look awsome. Has he got anymore😀

they will fit, just need to play around with the spring plates !
The upper shock mount will be mounted to the roll cage, so not fussed about that. The bump stops may need some work ! They are about 75mm in width over the standard arms, but I'm having wheels made so I'm not fussed about this.
The only hassle is that I don't want to use the disc brakes due to the cost ! I would then also have to customise the front brakes to match, to much $$
well I can use the ally ones, but the stub axles are different to the ones you fit to beetle trailing arms🙁
If I find the steel trailing arms (which I have 😀) then the stub axles are the same as beetle, just has a larger CV flange. The steel trailing arms look identical to the IRS beetle/T3/superbug arm from the outside but has internal strengthening. It also comes with the porsche discs or drums. The backing plates off a beetle/T3 will fit.
As much as I love the aluminum arms, the steel arm option would be better for future spare parts etc as more beetle parts are interchangeable with them ie bearings, stub axle, brakes.
So I get stronger CV's and better CV angles using the 924 stuff (no need to modify) Stronger trailing arms but look the same (no need to strengthen) and the option of factory fitted disc brakes ! Cool :thumb
maybe, but if your interested then I should still be :P so no.......................maybe.............................no......................................will think about it ! but 555bug has first option 😀 for his help !
So does this mean the stub axles in the aluminum arms are different to the steel arms ?
If I have to run discs,what would you suggest for calipers and the front.
Hi Craig
Sorry my post was little hazy, Im getting over a wog, those cold and flu tablets give great dreams.
The steel 944 arms use a bug compatible axle and bearing, the alloy arm axles are different, im not how.
As for brakes, try too match what you fit on the rear, single piston 994 with the same on the front & so on.
If your only going to do hill climbs the rear discs maybe overkill and might not heatup properly. Make sure you get the correct spring plates for the arms, it a bit of work to fit them but being able to adjust toe, camber & height easily is worth the work.
Umm, Craig, take this with a grain of salt cause I'm only half serious......... Are these just for the wank factor ? or is your buggy heavy enough to need stronger rear trailing arms ?
Just curious, if you arent interested for the brakes, why bother ?
Like I said, please dont take offence, just dicussing and not trying to get personal.
i believe that the 924 turbo has an identical set up to the 82~86 944 ie single piston calipers, steel arms. In 86 they switched to twin piston calipers on steel arms, I believe that the alloy arms are from a 968 (late model 944) or perhaps from a 928 (v8 hmm).
Don't know if they help. Brad had aluminium 944 gear floating around for a while. He might of even stolen the stubs. I thought the stubs looked about right, they just had ABS teeth around the flange. But I didn't look very closely.

The buggy needs to be reliable, strong, functional offroad, and easy to replace parts in the future. I want to use the minimal amount of engineered/custom parts as possible.
Therefore the Kombi gearbox was chosen (good diff ratio and strength), this obviously needs to use Kombi CV's (using porsche,better angles) the stub axles then need the larger flange (porsche fits without mods), and when I started looking for the Stub axles I found I could get the whole arm (including disc) for the same price ! So I starting thinking.....:jesus....... why pull the stub axle out of the arm, when I could just use the whole arm !!! The reason I wanted to use the drums on the rear was to save the hassle of having to replace the front etc etc. and finding calipers for the rear .
The strength factor of the arm was an added benefit, but I feel that when the buggy is fully loaded for camping/touring it will be heavier than a beetle .
Its not a wank factor using the steel arms, as from the outside they look the same as Superbug trailing arms.:thumb
This buggy needs to be able to go all the places my Pajero went, without bending cracking or breaking anything. So this is why I'm going this way 😀
I will probably use the discs with a brake bias control 😎
:thumb my 76 beetle is my hillclimb car, the buggy is my midlife crisis car😀
I may use the alloy arms, just concerned about the modification etc to the spring plates etc.
If I damage a steel arm, at least I could replace it with a beetle one to keep me going ! If I damage an alloy arm, say in Kakadu, I doubt whether I could find a porsche one in a hurry🙁
the wider track would be good, as I could then use kombi axles and the Cv angles would be less for the same height . :thumb
Just a note about 944 handbrakes, they will hold you on a hill but thats about it, they dont really make much difference if you pull them on at speed, if you want steering brakes you would need to go hydraulic.

craig, the brake bias adjusters are about $150 from the big race parts shop whose name i can't remember after all these beers. ( 61 to 100 % front)(i think)

I was playing with the aluminum arms today and decided that there is to many mods to do. Internal hand brake,sourcing calipers, modifing spring plates, changing bump stops etc etc. Defeats the purpose of being easy to replace parts if/when I do damage ! For what I see as minimal gains.
