I have a '90 C4 -- Willing to buy 21MM OEM rear fixed sway bar to minimize understeer

Must I buy the sway bar only or also the bushings and other parts ?

Tips or links ?

964C4

Do you have the part or parts number ?

It's the fixed rear sway bar of C2 year 1990

The list below is one I stole from Puma1824. Kudos to him for making it available.

He pulled this list together. You need everything here. Buy one from a Porsche dealer. I bought a used one on Ebay and paid more then these prices for new.

Best of luck.

Do you need the bar and bushings? I happen to have one sitting on the floor of my shop from a '90 that I removed during my suspension upgrade. If you want it.. I'll make you a good deal..

I'll have to verify that it's a 21mm but it's a stock bar from a 1990 C2.

If 964C4 isn't interested, I am. Regards, DanzC4

C4Russ: thanks for this superb information !

FotoVeloce: what price and can you check the part number, please ?

Cannot find my calipers and the PN is hard to read but it *looks* like:

964.70107 or maybe 964.10107 both 7's look like they could be slanted 1s

Does that help? I honestly dont' know the exact size of the bar until I find my dial calipers.. :/

AH! Here is a pic of the part # on the bar.

PS. That's not corrosion on the bar.. it's muck that I'd not taken the time to wash off.. just tried to clean it enough to see those numbers.

964C4

Thanks for the reply, but the part # should be:

964 333 701 07

Have you measured the diameter ?

FotoVeloce

I'll measure it when I get back home tonight. Werid thing is that there is no provisions for the '333' (or any other number) but the initial 3 and last 5 seem to be the same. I'll clean up the bar and see if there are other part numbers on it, and hopefully my dial calipers will appear from whatever corner in which they are hiding.

I highly recommend this upgrade. I bought the 21mm bar on ebay for $70, and the remaining parts listed above from Puma1824's list new from Sunset Imports (of course, no affiliation, just a customer). This combined with a stut tower brace have significantly minimized the standard stock understeer on my C4.

I too have the bar all ready to put on my C4 which appears to be exactly the same as Ave's. Are there any tricks to the installation, or is it a simple "unbolt the old, and bolt on the new"

Thanks, Craig.

Should be just a simple swap, as the frame mounts and drop links are the same. I have the TRG 3 way adjustable, and it fit no problems on my C4, using my stock drop links.

That's what I replaced that rear bar with, the TRG adjustables. Once the entire rear is up in the air, drop the forward pan (cover) and it's a really quick/easy job.

Not like the front. Even with most of the front suspension out it took some thought to get the forward bar weaved into the right possition.


PS. I could not find my dial calipers so I bought some new ones on the way into the office today. I'll measure the bar when I get home. Of course the new calipers cost way more than the bar, but.. I needed some new ones, right?

Rear bar (pictured in previous post) measured out at 21.1 mm in the center and on the ends.

Being curious I measured my stock front. It reports to be 20.2 mm Interesting that the stock bars have a smaller front than rear.
