Trailing arms are a common suspension upgrade for the FD. The factory lower arms come from Mazda with a flexible rubber front bushing. Bushing flex adds an element of unpredictability and is definitely not desirable. The TC Sportline trailing arms cure this problem. The front bushing is completely eliminated with ultra strong Chromoly heim joints. Additionally, these arms are designed to allow more clearance for wider tires and wheels.
The stock toe links have rubber bushing and are skinner then the aftermarket version in most cases. TC Sportline Upgraded toe links are larger in diameter, so it’s a stronger replacement over the stocks.They have spherical ball joints that will reduce flex and provide tighter suspension response. They also allow for more adjustments to suspension geometry as needed for competition driving.
