The Fays roll center is adjustable where the Saleen is not. However my understanding is that the Saleen being fixed in the center of the differential is exactly where you want this anyway(?).
As to the urethane vs. solid bushings on the WL - I'll have to look into that.

Your question regarding the roll center height adjustability will have to be answered by those more knowledgeable than me. What I have learned from this and other respources, inlcuding starting to reread my suspension and handling books, is that everything is related and complicated and what you do in one area affects other things. It is also dependent on what you want to do with the car and how hard you want to drive it.
In the thread above F1Fan states "the one thing that I have not been able to fix is the different feel of the car when turning left vs right. This is due to the simple factthat the roll center is moving up and down and rightand left even when the car is driven in a straight line and this iseasily felt when driving through a corner or a series of left/right turns. The more you optimize the chassis the easier it becomes to feel the difference between the Panhard bar car andaWatt'slink car.".
This indicateshe is has already made enough other changes and is drivng the car hard enough and is a good enough driver to be able to tell the difference with a Watt's Link compared to a Panhard bar. I doubt if I will ever reach that level of capabilty,
One of my personnel objectivesformy car is to be able to get safely and quickly around Mosport during our local clubs track dayin June. What will also be interesting is to get my brother's opinion on howmy car handles as he is a die hard Porsche fan and has lots of seat time at Mosport in both road and race cars For those of you not familiar with Mosport here is a track map - http://www.mosport.com/trackmap.htm. What is missing from the map are the elevation changes and the areas where the surface changes from asphalt to concrete. These add to the challenges for the suspension and driver.

RE: Watts Link - Which?
For those who are interested here is a link showing how the Saleen style Watts linkage works http://en.wikipedia.org/wiki/Watts_linkage. Note that the idea dates back to 1784!
From what I can rememberthe other style has a pin on the back of the differential and the pin slides up and down in a vertical "Slot" in a bracket mounted rigidly to the chassis.
If you also click on the two pictures on this Saleen page you'll see their parts in detail http://www.saleen.com/SC101_Services...10-1007-A16241*
Note that I have used the common spelling of the name, "Watts", linkage instead of the correct spelling "Watt's" as the Forum search engine considers the single quote.
