I had a conversation with a friend who owns an A1 vw rabbit. It dawned on me that my car shares some suspension components with vw. So here is the question. Has anyone looked at Early VW performance suspension for upgrades to our cars? For example Tubular Lower Control Arms for the front suspension. Just a thought.

I have VW Rabbit control arms on the front of my 924. $30 vs $130 for the Porsche equivalent. I don't see why performance tubular control arms for a Rabbit wouldn't work.

From an article I posted some time back:

"The engine was Audi's 1984cc LT commercial unit with an overhead cam head from VW. Suspension used Superbug bits, VW Scirocco lower control arms and steering, and disc/drum brakes from the VW K70."

I've wondered ever since then whether, if someone had the time to do all the parts cross-referencing, we could take advantage of the huge amount of work that's been done on hi-po VW parts? The problem is knowing exactly which parts were used where. It would be a Herculean effort to track down and cross-reference all the part numbers, then search out all the upgraded/after-market/hi-po replacement parts available. But I've got my suspicions it may yield some great upgrade options...

That's where my front spherical bearings come from - they're VW A1 chassis aftermarket parts, and cheap - only $285 a set. The equivalent parts from Racer's Edge are about $500 IIRC. Of course, the RE parts are a much nicer design, and I'd go with them next time around...

The suspension is derived out of necessity from parts already in production. The control arms are not the same but can be used as the VW units have no sway bar tab. The struts are from a super beetle as well as the rear trailing arms. The brakes are unique to the 924 but the drums were sourced from the ROW VW product line. I like to call this:
Parts bin engineering at its best! The door handles give it away as to the bloodline of this car.

The 924 front sway bar can be adapted to the VW control arms using the inbound holes on the VW items.

I have both parts in stock. seam-welded and powder-coated for all years. choose your color.

Good point here on the seam welding, I've been told it is a must for the rabbit arms.

I think you mean to say that the rabbit arms will fit directly to a 944 with the use of early mounts. The 924 sway bar cannot be used with the stock drop links with Rabbit arms. A simple tab can be made for this to work.

The 924 front sway (at least the 1980 version) bar can be adapted to the VW Rabbit control arms using the inbound holes on the VW items, without having to mount ears.

You can use the hole in the arms to mount the links for the sway bar arms, but they are not designed for the that. If you do use them that way, the arms crack. I have seen lots of ruined arms that people have done this do that indicates that the arm holes must be reinforced if you are going to go this less expensive direction.

Since the holes are not located where the original mounts were, the angle that the links hit the swaybar is also changed, which means that the swaybar will not act on the car with the same force that it would will the original factory links in the designed locations.

True, with this method the arms must be reinforced at the holes, just as they should be seam welded before installing. The angle of the drop links is changed, but I've noticed no difference in hard street driving. Maybe if you track the car you would notice a change.

Why not do it right?

Welding plus rabbit a-arms is much cheaper than the $130 each 1980 Porsche a-arms with the ears pre-welded. I don't usually skimp on parts, trust me I've got the binder of receipts to prove it, but I just couldn't stomach the price of Porsche a-arms when there was a reasonable alternative.
