The IronBox adjustable rear trailing arm brackets replace the original brackets on compatible BMW E36 and E46 rear suspension setups ⠀ The extended adjustment slots provide up to ±2° of additional rear toe adjustment relative to the standard suspension geometry ⠀ This additional range is useful for configuring rear toe for drift competition, correcting the geometry of lowered vehicles, or compensating for alignment deviations caused by previous chassis damage ⠀ The bracket construction also limits unwanted lateral movement of the rear trailing arm bushings, helping create a more controlled and predictable rear suspension response ⠀ Main features ⠀
Extended rear toe adjustment — provides up to ±2° of adjustment relative to the standard geometry
Bolt-on OEM bracket replacement — installs in place of the original rear trailing arm brackets
Drift setup capability — allows rear toe to be configured for different tracks, grip levels, and vehicle setups
Lowered-vehicle geometry correction — provides additional adjustment when the factory range is insufficient
Chassis geometry compensation — may help restore the required toe setting on vehicles with alignment deviations
Reduced lateral bushing movement — helps control side-to-side movement of the rear trailing arm bushings
More predictable rear suspension — improves rear axle stability and feedback under changing loads
Steel construction — provides a strong replacement for the original stamped brackets
Powder-coated finish — provides corrosion protection and a clean appearance

⠀ Rear trailing arms, rear trailing arm bushings, and replacement mounting hardware are not included ⠀ Important bushing information ⠀ The brackets are designed to limit unwanted lateral movement of the rear trailing arm bushings ⠀ Separate RTAB limiters or restrictor spacers may be unnecessary and their compatibility with these brackets must be confirmed before installation ⠀ Compatibility with oversized polyurethane bushings, spherical-bearing conversions, and other aftermarket RTAB solutions must also be confirmed before ordering ⠀ Important installation information ⠀ A complete four-wheel alignment is required after installation ⠀ The rear toe setting must be adjusted equally and correctly on both sides of the vehicle ⠀ Inspect the rear trailing arm bushings, trailing arms, chassis mounting pockets, threaded mounting points, and installation hardware before fitting the brackets ⠀ Damaged or cracked chassis mounting points must be repaired before installation ⠀ Ensure that the bushings move through the required suspension range without binding against the brackets ⠀ All fasteners must be tightened to the correct specification and inspected regularly during motorsport use ⠀ Installation, suspension adjustment, and final inspection should be carried out by a qualified specialist
