Not only that...
When I was running 350lb coil overs up front, I had the MM 380-430 (or whatever the stiff TA springs are) in the rear and the car was so softly sprung in the rear it would lift the inside front tire 2-3 inches off the track at MAM. I have since gone to a 500 lb circle track spring intended for the font of a car...using a Griggs adapter and the tires stay planted.
