Hello All,

I need new trailing arms/control arms (not sure what to call them) and would like some adjustable or more performance oriented ones rather than OEM ones. Is there anywhere I could find them or do people not make them? If there are ones, my car will be more street oriented but would go to the track every so often. Thank you for any advice you all bring.

 

Why do you think you need new trailing arms? Unless they were bent in an accident or have rusted to the point of being structurally unsound, just repaint them and install new bushings.

I don't think anyone makes aftermarket control arms. The arm itself is one big piece of metal, it doesn't provide any sort of adjustment. Toe is adjusted with an eccentric bolt on the outer control arm bushing in stock form, but you could get aftermarket toe links (the long ones running from the middle of the subframe to the wheel hub) if the stock adjustments aren't enough. Camber is fixed from the factory, but you could get aftermarket camber links / dogbones in different lengths or fully adjustable ones (Mazdatrix or AWR) if you lowered the car and have excessive negative camber.

This thread gives a nice overview of the rear suspension if you're not familiar with the setup:
