Bernie, your set up with this suspension is incredable! Im looking for every bend or turn in the city i can find to push the limit
Driving a RS with a well tuned suspension serviced by somebody who understands 997 CUP/Grand-Am cars can really help unleash the possibilities of the 997 platform and such knowledgeable service is an asset to any 997 owner looking for proper professional care of their Porsche.
no other auto maunfacture/marque is this much fun to tune!
looking foward to more tuning fun in the future!

A plot of the toe change would be really nice if possible. Are you having both the front and rear bump steer set?

The stock car doesn't have a flat (parallel) toe link, so it is already more sensitive to dynamic toe changes (bump steer). It was even worse in the 2004 GT3.

^ Here I am, reading about bump steer this and bump steer that, wondering what it is (as an adjustment as in "I'm getting by bump steer done"), do a search, come up with a gazillion threads and Rad (?), you just cleared it up with two short sentences. Thank you

You just want the toe link parallel to the ground with the car at rest. Add spacers until you reach the flat angle, this will provide you the most stable dynamic toe.

Don't make me borrow a bump steer gauge and do the work myself... please!

Yes, everything is a compromise, what you gain in bananas, you lose in oranges, so what would be the downside of having a setup that minimizes bump steer from the factory? Maybe loss of travel, so loss of comfort on a "road" car

So as long as I'm exposing my ignorance, why wouldn't the factory want to achieve the "most stable dynamic toe"?

Fortunately the fixes are easy and considering the benefits, cheap too however.

The toe links from the 997 GT3 are from the 996, the dog bones are shared by the standard Carrera and Carrera 4S (and Turbos and Cabs). Reusing parts saves them money, but brings you less than ideal geometry.
The older the GT3, the more they share parts with the Boxster and Carrera.
