You are right, but a little difference is that he have an M3... DSC Sensors are specific to Exx M3 & 1M

i will make a test tomorrow to verify if mechanically, the Exx no M Sensor fit in the Fxx M knuckle.

About the screws i think that you can make a test with it, but after, it would be better to fit new screws because they are probably "torque to yeld" styles, & for brake calipers it is really better to fit new ones IMHO. with nord-lock washers / or strong loctite.

Did you ever machine the spacers?

what do you think about the cover plates?
Do you thinks it is better to fit the 380mm Fxx M types 34112284743/4 or the 360mm Exx M types 34112283723/4?
(if i am correct, no M types have a different shape & won't fit the knuckles)

Yeah he have m3, i mean in 335 But he have m3 and also he use Bearing of e9x m3

Not M sensors, almost in measures if i not bad remember is same as m3 sensors.

Maybe is possible use e9x not M bearing and wheel mount. With this os possible use original dsc sensors.

My 4x screws from subchassis are new.
In this days go to machine spacers and screws.

Coverplate for moment i not buy, when i have all mounted, i buy this.
First i will try with not M coverplate maybe add new drill... if nor way.
The best way is e9x 360mm But im not sure if have same goles as m4 knuckle

"Not M sensors, almost in measures if i not bad remember is same as m3 sensors."

you are correct, measures are exactly the same & not M E8xx fit 100% in M Fxx knuckle. there is one only one difference in head orientation which have an 90° offset. I hop electrically it will be OK.

if not work, we can try with F ///M sensors in my case knuckle come with this.

Mine come with too, but one was cut.

By the way, the connectors are not the same. ..

i have male and female connectors if not work with original sensors, i will try. if work with F ///M, i send you part numbers

[ruben_17non]

Ready:

[ornicar]

Perfect! you are faster than me i hope that it will match 100%

[ruben_17non]

i order:
1x 34112282445 Brake disk 345x28MM L
1x 34112282446 Brake disk 345x28MM R
4x 34111123072 Screw for M disks
8x 36136890324 Wheel bolt M14X1.25
1x 33326768884 Nut M10
1x 07119905418 Screw M10 for strut carrier
1x 34522283398 Bracket for ABS and brake tubes R
1x 34522283397 Bracket for ABS and brake tubes L

Dust plates for moment i not order, and brakets for ABS im not sure if is need.
if is need change DSC Sensors i will try with M4 sensors, only is need change connectors.

I hope I have not forgotten anything about order

the second picture, is Fixed with CSL disk because is bigger

Hey,

i have tried to fit the discs today, with the 9,8mm spacers it is Not OK, the caliper touch the disc. I have to put some 1.2mm washer to perfectly center the caliper. maybe the offset of m3 e46 discs was not the same that the csl ones?

so correct spacers have to be 11mm.
