porsche arms or just stub axles
I have some porsche steel trailing arms, for those wondering they aren't very different at all to the beetle ones except the stub axle is 100mm and
the spacer I think is longer.
My question is, Is it easier to swap the whole arm which has drum brakes to remove and clean and paint or remove just the stub axle only?
2nd question do I use porsche 924/944 cv's or kombi ones, or are they exactly the same strength and price etc?
Cheers Kris
P.s the reason I need the stub axles and spacers is to have wider track engineered.

the stub axle is the same as beetle (except flange) so it will fit straight into your beetle arms.
Kombi and 924 CV's are the same.

Do you want to rebuild your arms with new bearings etc, or just fit the stubs ?
If you are just fitting the stubs, it's just a matter pushing the beetle stubs out and pushing the porsche ones in.........its relatively easy.

Yeah I think the bearings are all in good condition still, possibly rebuilt when the project started, so I just need the stub axle.
If I have the stub axle with the 100mm flange on it the engineer will no they are from a porsche and engineering wide porsche wheels is easier.
Basically if I have porsche stub axles then I can have porsche wheels and track.

Thats funny needing the Porsche stub to run Porsche wheels. I can see from a strength reason that it works for Porsche so kinda lazy engineer as in
Europe loads of people run Porsche alloys with spacers on beetle stubs and never heard of one breaking.
Anyhow, what style Porsche alloy you fitting?

Yeah I also believe they'll never break, thats what a lot of people say but there is no way of fatigue testing beetle ones, so its the easiest way to
get a wider track engineered. Its just another thing to do trying to get an ej20t bug on the road.
The wheels are 18x8-10 om simmons

Least with the EJ20T you don't have to worry about the stub shearing as people say 150bhp is the max for Beetle stubs  Never been proven as it's always shock loading that does it.

150hp...never heard that one. I think the weak point is the cv and that has more to do with the suspension and as you said shock loading. Stock VW irs
(double joint ) axles are very strong!!!!

Swing-axles aren't bad, either........and no CVs to worry about.
I'd rather wear a Beetle out by racing it than by polishing it!

Like I said one thing I've heard here and there but never proven as seen many a drag bug do fine with them.
CV is the weak point and less likely to snap then a SA shaft
