e9X speed sensor questions for F80 brake upgrade

Blanky · 07-30-2023, 10:49 PM

I’m about to upgrade my e92 M3 with the following OEM kit:
F80 M3/4 calipers + rotors (F&R) + F80 Front knuckles but I'm stuck on whether to:
A. Use my old (e92 speed sensors + spindles/hubs) and modify+rotate the e92 speed sensor 90 degrees to get it to work?
or
B. Use (F80 M4/3 Speed senor + spindles/hub) and wire them into the e92 wiring. (this I would prefer if it works)

I have also read the e92 spindle/hub will fit on the F80 knuckle but I don’t know if they are matched with the corresponding model series sensors.

I have read a few posts some of which are conflicting on this topic but none have clarified this detail 100%.

Many thanks

The hubs are allegedly interchangeable but the F80 hub is a nicer part than the E92 so you're losing some advantage by keeping the E92 part. If I were doing the conversion I'd use an F80 sensor and splice on the E92 connector using solder and high quality heat shrink with sealant in it.
