IronBox BMW E30 / E34 / E36 Compact / Z3 Rear Camber & Toe Plate Kit

The IronBox Rear Camber & Toe Plate Kit adds adjustable rear suspension geometry to BMW semi-trailing-arm rear axles that do not provide sufficient factory camber and toe adjustment
⠀
The steel plates are welded to the rear trailing-arm mounting points on the subframe and work with eccentric bolts to change the position of the trailing-arm pivots
⠀
This allows the rear wheel alignment to be corrected after lowering the vehicle or configured for drift, track, stance, and other performance applications
⠀
Main features
⠀

• Rear camber adjustment — allows excessive negative camber caused by lowering to be corrected or additional camber to be configured
• Rear toe adjustment — allows the rear toe setting to be corrected for improved stability, handling, and tyre wear
• Weld-in installation — plates are welded to the existing rear trailing-arm mounting points
• Two hardware patterns available — choose plates designed for BMW or VAG eccentric hardware
• Eight-piece kit — provides the plates required for adjusting both sides of the rear axle
• Raw steel construction — supplied without coating because the plates require welding during installation
• Suitable for multiple applications — useful for lowered street cars, stance projects, drift cars, track cars, and custom suspension setups

⠀
Compatibility
⠀

• BMW 3 Series E30
• BMW 5 Series E34
• BMW E36 Compact — E36/5
• BMW Z3 Roadster — E36/7

⠀
Important installation information
⠀
Professional welding and suspension alignment equipment are required for installation
⠀
The rear subframe must be inspected for cracks, corrosion, deformation, and previous repairs before installation
⠀
The mounting points must be measured and positioned correctly before the plates are welded because incorrect positioning can reduce the available adjustment range or prevent correct wheel alignment
⠀
The eccentric hardware must be tightened to the appropriate specification after the final camber and toe settings have been established
⠀
A complete four-wheel alignment must be performed after installation
⠀
Installation by a qualified suspension specialist and welder is strongly recommended
