Regular price $489.00

This kit allows you to retain your original E30 rear trailing arms but utilise newer components for 5 stud conversion and to gain vented rear brakes.

The basis of the kit is the special hubs we supply along with caliper adapters to allow you to use calipers from the models listed below, along with a matching 294mm vented rotor:

Calipers/Rotors from:

E46 325Ci/325i

E46 328Ci/328i.

See attached images for 40/19 marking on caliper and 506 marking on caliper carrier to ensure the correct calipers are used if sourcing your own.


Base Kit Contents:

1 Pair of NEW 5 stud hubs

1 Pair of E30 rear wheel bearings

1 Pair of caliper adapters and Hardware

 We are no longer able to supply a full kit with calipers but please contact us for any additional information on fitting this kit.


This setup will only move your rear wheels out by about 2mm from the factory 4 stud location which is much less than the other 5 stud options such as 318ti rear. The factory handbrake is still compatible with this brake setup and does not need any modification to fit. Standard E30 axles match the spline of the new hubs which means this is a bolt on solution once the new hubs and bearings are installed.

Small modifications to the dust shield may need to be made on some cars along with brake line placement.
