With the PORSCHE 996 calipers and M3 E46 brake discs we offer a really nice brake solution for the E30 included a 5x120 conversion in front.

The brake and the ABS ready 5x120 hub solution make the E30 axles 15mm widther then standard 4x100.
Wheels should come from the 3er series BMW E36, E46, E90 Z3 Z4 with offset from 30 - 47mm. Picture shows BBS RC 040 7,5x17 ET47 from E36 on E30 with 20mm additional distance plates.
This solution doesnt work with E38, E39, E32, E34 wheels on E30 standard body, but these wheels are ok for Pandem Bunny rocket E30.
On rear you should work with the E36 323ti compact hubs on standard E30 Suspension to make the 5x120 Conversion. This make 19mm more each side, perfect for the ET35-46 wheels. With my Adapter 294-8B you can mount PORSCHE 986 calipers on the E30 together with 294x19mm discs from Z4 2.5si E85 Series.
