i would say not enough rear bias to keep the rear end planted...i've found that getting the rear of cars to do more braking has helped settle cars down in brake zones (less weight transferring forward keeps the rear end from getting 'light')...of course this is with bmw's so it may be way off for porsches 
and as almost everyone else has said, check the rear alignment...

yes, you shifted the bias forward (more so than it already was) making the front brakes do more work and causing more weight to be transferred towards the front under braking...

I agree with the LSD. When I had mine upgraded to 50/80 it dialed most of the squirminess out.
Also switched to the Turbo S brake bias valve for more rear bite to help offset the big blacks in front.
What about more rear wing??

Thanks to all of you for your input.
A couple of follow ups, first, if I change to Pagid Yellows up front and keep the blacks in the rear would that equalize the braking front to rear, correct?
Second, anyone have a suggestions on what toe settings would reduce the squirm vs. what seetings would caused more of the problems.

I currently have been running 1.3mm of toe-in in the rear. Guards Transmission told me that normal break away numbers are between 45-60 ft lbs. Two events ago, my break away numbers were 53 ft lbs, which GT said was good and in spec. The locking diff is 80/50.
diff is less than a year old with only 6 race weekends on it.
