The IronBox Drift Version adjustable front camber-caster plates are designed for BMW vehicles with coilover suspension where the adjustment range of conventional coilover top mounts is insufficient ⠀ Main features
Expanded camber adjustment — allows the damper position to be moved within the available strut tower opening
Selectable caster orientation — the top mount can be repositioned in 15-degree increments to change the adjustment direction on all listed chassis except BMW E30
Coilover-specific construction — designed for suspension systems using a separate upper spring perch
Motorsport spherical bearings — designed to withstand high suspension loads and provide precise damper movement
2024-T4 aluminium alloy plates — provide a strong and lightweight mounting structure
Steel bearing housings and adapter sleeves — provide strength around the damper shaft connection
Protected component surfaces — aluminium components are anodized and steel components receive a BLACKNITRIDE anticorrosion treatment
Optional E36 / E46 tower reinforcement plates — matching weld-in reinforcement plates can be added for BMW E36 and E46 installations

⠀ Important installation information
The shock absorber shaft diameter, thread and coilover spring-perch configuration must be checked before ordering
The strut tower opening must be modified to provide access to the adjustment screws after installation
The available camber and caster adjustment range depends on the chassis, coilover configuration and size of the modified strut tower opening
Installation with matching reinforcement plates is recommended for BMW E36 and E46
The optional reinforcement plates require welding and must be installed by a qualified specialist
A complete front wheel alignment is required after installation or adjustment
Spherical-bearing top mounts can transmit more noise and vibration into the vehicle than factory rubber mounts
All mounting hardware must be correctly tightened and checked after the first drive
