I had the softest rear sway bar in my M03 on carpet, and the Car kept sliding at every turn eventhough I had type A slick Tires in the rear... I removed the swaybar, and the rear stayed planted. I use red springs, 80wt oil all around... I also had a swaybar on the front, and it made the front too stiff, so I took it Off... The M03 seem to Work well without any swaybar, but I did limit the droop with spacers inside the shocks...
