Dumb Question Thread - No Flaming Allowed

[0-60motorsports]

Not really applicable to the E46 M3 but I haven't had any answers on the M5 boards.

The S85 (as does S65) has a bedplate that forms parting lines on either side of the F.M.S/R.M.S so when replacing these seals your are supposed to use a special prepping compound/adhesive.

It's about a $150 kit for the prepping compound,"sealant" syringe/needle/tool to push adhesive from syringe.

I did the FMS on my S85 recently and just smashed some Toyota FIPG into the parting lines and called it good.

I am now going do the RMS as part of a LW flywheel install but want to know just how important,or not, the use of the correct adhesive is.

Yes in theory you should

Dont want to spam the dumb questions thread with my FCAB issue too much, but figured followup with pics of my findings. So; faulty install by my indy’s mechanics when doing the new LCAs last year (had the Turner FCAB installed by them prior that, ~2 years ago) OR had the FCAB just failed/broken?

Thing is i had seen that the passengers side had that crack right after the lca install but didnt think much of it… i didn't complain to the shop thinking it was just a superficial plastic outer piece and there was no noise or creaks at the time. I feel if it was broken before they did the lca install they would've said something.

Also I wasn't able to replicate the creaking sound with the front end in the air unfortunately.

I have the same issue on mine (not as bad), however mine are about 3-4 years old at least. I need to replace them fairly soon.

what offset would be ideal for a 18x9 wheel up front to run without spacers? have full adjustability with coils, camber plates, etc

Look like it broke right at the cast line
