Is there a "sweet spot" for lowering the suspension for tracking an ITR?

It looks like there are a bunch of ITR folks with coilover experience on tracks. So there must be some concensus as to how far you can lower the suspension on the ITR and see gains with a stop watch and pyrometer, and not bind the suspension/throw the geometry out of whack.

 

I drive a GS-R on ground control coilovers, and measured from the jack points on the corners, the front is 5 and 3/8 (ground to jack point) inches, and the back is (cant remember the back) it seems to be the idle set up from talking to everyone...hope this helps you out in anyway...ask Warren (username on the bard). He and some of the other ECHC ITR boys would be the best to ask.

 

I lowered my GS-R until I had about 2 degrees of static negative camber and called it soup. Tire temps = pretty even.
