I am also running the old skool front end on my Quad 12.
Servo shoe gooed flat to the chassis and pushed forward with ball stud in the back of the servo saver.
.020 front springs with 5000wt diff oil on kimg pins
0.5 degree toe out, camber set so tire wear flat
T.M. Purple or Cyan, or Magenta front tires
In my CRC tubes, I am currently playing between Mugen 5000wt diff oil and Corally Red Stuff (which I find very stiff).
Adam the blue stuff must make it super stiff
