$
110.00
This IronBox kit is designed for installing compatible BMW E36 or BMW E46 front brake components on the BMW E30 front axle

The kit contains front caliper adapters and installation hardware only

The adapters required to install BMW E36 or E46 front hubs and convert the original BMW E30 4×100 configuration to 5×120 are available as an additional option⠀

Before installing this kit, the vehicle must be equipped with a separate BMW E30 hub conversion adapter kit and compatible BMW E36 or E46 front hubs

The conversion uses matching BMW E36 or E46 front brake discs, calipers, and caliper carriers

The selected brake components must come from one compatible configuration and the caliper carriers require modification for installation with the adapters
