The IronBox reinforcement plate kit is designed to strengthen the rear subframe mounting points of the BMW E46 chassis ⠀ Age, drivetrain load, hard launches, drifting, track use, and stiffer suspension components can cause cracks or separation around the rear axle carrier mounting points ⠀ The steel plates are welded to the affected areas of the body to distribute the load across a larger surface and reinforce this known weak point of the BMW E46 chassis ⠀ Main features ⠀
Rear subframe mounting-point reinforcement — strengthens the areas where the rear axle carrier attaches to the vehicle body
Helps prevent chassis cracking — distributes suspension and drivetrain loads across a larger section of the rear floor
Suitable for preventive reinforcement — can be installed before visible damage develops
Suitable for professional chassis repair — can be used after existing cracks and damaged sheet metal have been correctly repaired
Weld-in installation — provides a permanent structural reinforcement of the mounting areas
Formed during installation — the plates are shaped against the vehicle body for accurate contact with the original floor
2 mm steel construction — provides additional strength while allowing the plates to follow the contours of the body
Raw weld-ready finish — supplied without coating for correct welding and subsequent corrosion protection
Designed and manufactured in Ukraine by IronBox
