I really would rather get the Porsche specific ones, I missed a set a guy had, he offered them, I hesitated, and when I got back to him a day later they were gone
30mm Sway Aways. New they at right at $300
This is what a gent who bought the VW ones posted:
"The t-bars from CIP1 aren't an exact match. The difference is the length of the splines on the outside end of the bars. There are about 1/2 inch more splines on these bars.
Why is that a problem?
It's not, unless your doing the hole-saw-in-the-rocker-panels method and removing the end of the t-bar cover to just insert the new bars from the outside.
There's no way to seat the inside splines first because the outside start in the grooves first."
Then in another post:
"The Cip1 bars are in my 944, work fine. I did 28mm with 275lb front springs, pretty well balanced. The only difference I found was the length of the splines. Factory bars have less spline. After looking at the sway-away, I think they are the same way. Not an issue unless your trying to swap them without dropping the suspension."
The short coming is that they only go up to a 28mm, the internal debate is between a 28mm and 350lb OR 30mm and 400lb. Mark R runs the first one because he "likes the rear a little loose" his car is mostly likely a few hundred pounds lighter then mine and he is on stickier tires. John and several other folks run the second option and like it. Tim C mentioned that various mixes of those rateing are used and it basically boils down to driver preferance.
On the other hand I could try the VW's and be the test dummy for the club as it could save folks lots of money if it works.
If anyone has some for sale, let me know.
