Thanks All! I've been playing with settings today and here are the results. Understeer is all but gone. Final settings for shocks are 9 (softest) for fronts and 6 for rear. Have located a 21mm turbo sway bar (thanks Pram) which I will add and then should finally be set. By the way, my earlier post on corner weights should have been 651 for LF, not 951... I,m not that heavy.

I'm no expert, but the first time I tracked my turbo I had understeer as well. I added a strut tower brace for $200 and it made a huge difference. Understeer was almost completely gone - after I added larger front tires (245 vs. stock 225's) then my understeer was pretty much all gone.
You may want to add the strut tower brace if you have not alre4ady done so. Good luck!

David,
Like Rob, I upgraded to 245/35-18 fronts on 8.5" wheels and understeer is gone, gone, gone. At the track, I get 40 psi hot all around after starting with 32 psi cold front and back (Pirelli P-Zero C's). Still on original factory shocks with Eibach 7209 lowering springs. Handles beautifully.
More rubber up front really does the trick, and a 2 psi variance in air pressure can affect handling more than I would have thought.
