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.
