Control Arm Notes
Front lower, and upper/lower control arms are an L-shape variation. The forward leg of the control arm is set near to wheel center. The forward leg of the lower control arms is fitted with a "handling" bushing; the rear leg is fitted with a "ride" bushing. The "ride" bushing absorbs the brunt of road deflections while the "handling" bushing absorbs the brunt of the cornering forces. The "handling" bushing is 3-6 times stiffer than the "ride" bushing.

this will help us run the numbers and compare it to the Chassis Works & NAERC plans to see if the suspension can be adapted to work on your chassis.

Body width across ,front and rear the difference from Murcie & Ventador
which is wider C4 or C5 Front Suspension ,someone who know please post the difference
