21 Here is a shot of the front tubular control arm in place (before installation of the front swaybar). Multiple mounting positions in the K-member allowed the angle of the arm (relative to the ground surface) to be dialed in for differing ride heights. The MM tubular control arms featured a true A-arm design (meaning they featured a brace between the V section to improve strength). Though we chose the standard control arms for this performance street application, they are also available in forward offset configuration (revised ball joint location) which increases the wheel base by 3/4 inch. Note the new steering rack bushings and adjustable tie-rod ends.
