This full independent rear suspension is the only way to go. It is a true high horsepower package, with upper links and heavy duty CV joints. The upper link produces -.5 degree of chamber curve at 3/4 of local travel, especially during very high cornering loads.

A heavier car with great traction and 400 HP will be much harder on the same rear end. Our ends use the proven 9" Ford gears. Heavy duty Corvette u-joints and castors weld steel half shafts. We just don't have any breakage problems. For extra heavy duty high HP we have custom 4-bar auto hub uprights. Q: What widths do you have for your rear ends?
