Thanks again for your input, I am starting to think it's the sticking pistons creating warping in the disc. The pads aren't green ones but they seem to be tuffer than the disc so that could be a problem as well? I also want to reco the steering rack to eliminate that as a angle. The car has a bit of negative camber ( 1.8 ) because of the ra60 struts which is another element to the equation? They were done by IDB

Looking to get the reco kit for the callipers soon and get the disc machined , but probably after get another car for a month, I plan to put in the 4age rwd in that time as well !!

Slide pins got me thinking about my motor bikes front brakes, might lube up the pins on that sucker.
