The mating surface for the bolts look different, flat vs ball seat. But the bolts are different length and different thread pitch, so that has me thinking the e9x bolt has to be used to thread into the e9x wheel bearing on the f80 spindle. But considering this is what is holding the wheel bearing and everything attached to it (calipers, rotor, wheel, etc). I don't know if I want to risk putting a square peg in a round hole if you know what i mean. I may consider just using f8x wheel bearings as that conversion is possible also. According to realoem. f80 wheel bearing bolts are shorter (M12X1.25X45) and one time use. e9x is M12X1.5X60-10.9. EDIT: Actually looking at the wheel bearing part on realoem, it lists 3 different bolts and 1 of them are M12X1.5 so I assume that is the one I gotta use. I was looking at part #4 which is the bolt itself and only one was listed.

Kevin, can you tell us what size the rear spacer washers are? Also, how did you reverse the E9x speed sensors 180 degrees on the F8x spindle? Does your abs still work?

Edit: the M4 wheel bearing bolts are M12x1.5 not 1.25 with a round collar. At least the ones I have are. Last edited by jcl17; 08-26-2019 at 06:43 PM.. |

I updated my post adding the screenshot of readoem showing that under the wheel bearing part itself (#3) there are 3 different bolts listed. Where as the wheel bearing bolt itself (#4) is what I was originally looking that. 31206783065 is a M12X1.5X45 bolt with a ball seat that will fit the f80 spindle which is what I think is needed to mount the e9x wheel bearing in the f8x spindle. But I don't have confirmation as yet.

You can't put an e9x one in the f8x spindle. It will not sit flush.

The mating surface is what is different. Zoom in on the knuckle where the four hub bolts go on the m3 and do the same on the m4 one. Notice one is flat like any normal bolt. The other has a round ball indent like the female conical connection of a wheel lug where the lug nut goes. I wish Kevin would chyme in how he ended up with the project. I’m near certain the hubs are not interchangeable. At least not safely considering the bolt mating surfaces are not interchangeable. Anyhow. I have one m4 hub, one m4 knuckle, and one m4 brake rotor and caliper to experiment on my e93 m3. I’ll let you guys know what I figure out and confirm the hub bolt issue myself Later next week when all arrives.

I've done this project. Had same issues missing in topic.
1. Bolts. Because car was in parts had to find solution quick. On hands we had Audi bolts with rounded head witch fit perfect. You can see bolts in pictures but I don't have part number. 2. Abs sensor for DCT. Pull it out rotate 180 deg and mount. Need to make special flusher to hold it in place. 3. Washers to center rear caliper. Use 2 washers for one bolt. 4 washers for caliper. Final result on Eibach pro kit: Last edited by Nostra; 08-17-2019 at 02:51 AM.. |

Completed my swap.
Wheel speed sensors were still reading the wrong direction for me at 180. But if I turned it to the outside 15 degrees until it pushes against the spindle then check the live reading it started reading correctly, sorry I didn't take any pics. Maybe I'll try to get some later. The correct direction if you look at the old position is the screw should be pointing towards the outside, not in the down or up position. 31206783065 are the wheel bearing bolts I used. I only used 1 washer for each rear caliper bolt.

This is a quick mock up of Nostra's picture of how I positioned the sensor. I also tried 180, 90 to the left and both still read in the wheel in the wrong direction according to sensor data of the live stream

I tryed one, but it looked not center... I was more satisfied with two washers on bolt. Did you check if it's center?
How you test abs sensor readings? I did test drive, and after 180 degree rotation downshifts felt smooth again, so I fixed them that way. |

The Hall effect sensor "should" work in the original orientation and 180 out of phase as far as my understanding of this goes. Can anyone explain this ?

Perhaps your car is different, but I confirmed by reading what the car sees from as wheel speed and direction.
