E30 325i rear 5 bolt Hubs

[Bimsy]

Hi All

Is there a conversion out there to convert 4 stud to 5 stud rear hubs? I have an E30 325i rear trailing arms with new bearings in the hubs and I want to fit these to my E36 Compact 318Ti, However , the 5 stud hubs on the compact will not fit into the larger 325i hub bearings. Is there a 5 stud hub which will fit?

Z3 (6 cylinder) ????

Any help would be gratefully appreciated >

Thanks.

the 5 stud hub and 4 stud hub i have are the same sized length and diameter where they fit into the arm. the bearing i use on the compact is the same size as yours. The 4 stud arms i have off an e30 take the same size bearing. the e30 arms are off a 320i touring which i think was the only 2 litre with a disk braked rear so earlier e30s might have had different sized bearings. sorry its no help to you but my e30 arms take the compact 5 stud hub with the same size bearing.

Cheers, I`ve done some digging and found what B.M`s have the larger bearing fitted so need to get the car back and strip it down and measure the hub flange shaft. There are flanges that fit the bearing but I need to know if the splines are correct and that the shaft is the right length to fit the rear solid disc over.

Did you send over a picture? if so I couldn`t open it.

All sorted done some digging and found the perfect swap.

Using the E30 325i Trailing Arms with the bigger hub bearing I can use the Z3 3.0Ltr Hub Flange which is the same as my 318Ti flange but it fits the bigger bearing, result.
Bigger beefy bearing and Z3 flange !!!
