Offered by IRP, this kit of adaptor brackets for the BMW 3 Series E46 allows an extra pair of rear calipers to be fitted without welding and without any special modifications.
This kit must be fitted with a second set of E39 calipers. It is then possible to install a hydraulic handbrake on an entirely separate and independent circuit, a great solution for drift use.
However, the ABS sensor must be removed. It is essential to clean the contact surfaces thoroughly before fitting the brackets to the rear control arms using the screws and hardware supplied.
Installation requires rear brake calipers from the BMW E39 :
- Left brake caliper OE : 34211163649
- Right brake caliper OE : 34211163650
