Control are bushing or arm differences between Turbo and Turbo S?

[Streetcrawler]

--------------------------------------------------------------------------------

One of my lower front control arm bushings is torn. Its the rear frame end.

I know most just replace the entire control arm.

From looking at parts catalogs and the control arms them self it looks like the bushings can simply be pressed out and a new one pressed in.

There is at least one aftermarket company making a bushing for about $48 each.

The Porsche part number is 955-341-242 with about 5 versions. Some list as "Hydrolic" some as "Rubber" some as for "Turbo S) (IE8A) and some for (IE81) or "everything else". The Prosche part numbers vary in price from $30-$60 each depending on which version you want.

Unfortunately they don't give physical specs or even good pictures of the parts. I'd be really curious to know why the "Turbo S" is singled out as different. Is it just a firmer, maybe more durable rubber bushing that may provide a more sporting ride? Or is the control arm itself different with a different size hole in the arm? (the "Turbo S" arm is an assembly, so hard to tell if the arm is differnet or just the bushings. Part # FWIW 955-341-018)

Anyone?

The turbo S bushing is not a hydraulic bushing like the other bushings, it is solid rubber. I would assume its much firmer than a hydraulic bushings since the Turbo S was supposed to be much sportier. As for whether or not its interchangeable and will install in a non turbo S control arm, I don't know for sure. It would be interesting to read the E81 upgrade install instructions and see if it mentions anything in relation to this.
