MRT/GSP wheel-hub pair, BMW E36/E46 and Z4/E90
GSP wheel hubs for MRT E30 5-lug conversions or suitable original-part replacement applications. Choose front hub/bearing units or rear hubs. Supplied as two pieces.
Front hubs/bearings
- E36/E46 type. BMW OE 31226757024, GSP 9237002K.
- Includes the dust collar, nut and cap supplied in the manufacturer’s packaging.
- E36 and E46 non-M front hubs share the fitment. The E46 M3 aluminium-centre disc uses two retaining screws, so that application must not be treated as the same direct fit.
Rear hubs
- Z4/E90 LCI type. BMW OE 33416752381, GSP 9427034.
- Hub journal diameter: 42 mm. An E30 conversion requires a 42x75x37 mm bearing and large-bearing trailing arms, such as those used on 325i or facelift ABS versions.
E30 use requires the appropriate MRT adapter system. The rear-hub option is not listed as a bearing kit. Follow the vehicle workshop manual for installation and torque settings.
