Hey Karl..(after you cure the tweak issue).....60w oil all the way around In my opinion is "way" too thick for medium grip (or even slightly better) asfault with the stiff 3mm upper and 3mm lower BMI TC-3 kit...especially for the rear...Try 40w in the front.....30w to 40w Max in the rear(try 30 first) , 2 hole pistons front and rear (if not already)...Try "No" rear swaybar for stock and 19turn...and go back to a silver rear spring, and if the problem still exists (which I don't think it will) go back to your green spring....I run a set-up Just about the same as yours after you make the changes...(except I run 4.5mm ride height in front and 5mm in the rear).....and my car is dialed in really good for medium to high grip asfault on rubber tires, I switch back and fourth between a oneway and a spool ,and it runs great without any additional changes.....let us know how it works out....good luck
.......Joe
