Brake options for 5 lug adaptors on 51mm struts

[alistairolsen]

Hi,

If one uses a set of adaptors to run 5 lug hubs on standard E30 51mm struts, what options are there for larger brakes?

Thanks

Depends on the adapters. Most use E36/E46 brakes of which there are several brake size options

Front :
- e46m3 csl (345x28mm), piston size 60mm
- e46m3 (325x28mm), piston size 60mm
- e46 330i (325x25mm), piston size 57mm
- e46 325/328i (300x22mm), piston size 54mm

Rear :
- e46 330i (320x22mm), piston 42mm
- e46 325/328i (294x19mm), piston 40mm

Oh, there is a 42mm rear piston option from the E46....interesting. Though I guess that would still have parking brake fitment issues.
