Our E30 (Z3) Rear Trailing Arm Gussets are a weld-in part designed to increase the strength of the damper attachment point and hub body on the factory rear trailing arm weldments. This product is ideal for those looking to run true coilovers, race dampers, or simply increase the rigidity of their E30 or Z3 rear trailing arm. Our gussets are perfectly tailored to fit the geometry of the factory arms, meaning that our gussets require no modification prior to welding them in place.
Manufacturing: The Trailing Arm Gussets are CNC laser cut from .120″ mild steel sheet. The cut patterns are then CNC formed to exact design dimensions ensure precise fit against your factory trailing arms.
Notes: These reinforcement gussets must be installed by a competent fabricator. All areas where the reinforcements meet the trailing arms must be prepared properly prior to welding. It is up to the fabricator/installer to verify that any chassis modifications made meet the regulations of any event rule book the vehicle may be subject to.
