This is a set of rear trailing arms for your Cadillac ATS-V chassis. Available for both coupe or sedan and includes the '13 ATS (non V)
They are made of .120 tubular steel and have solid polyurethane bushings, far superior to the factory pressed sheet-metal arms with rubber bushings.
There are 3 bars per side, so this complete set will include 6 total bars. The install should take less than two hours.
They are a huge improvement over stock. Far more stable in the rear around corners and straight line acceleration.
