Also ordered M3 lca and rear subframe bush inserts, so much for just sorting out a dodgy shock absorber

I think that should be it for the suspension should I hold off doing the lca until I can get an alignment done straight after? Was going to attempt to do the b12 kit, bush inserts and lca all on the same day, and if I can’t get the alignment done afterwards it’ll be about a week until I can get it done? Been reading the car will drive awful until it’s aligned

If you swap over the LCAs, you won't be able to use it without getting the alignment done. If you propose to drive it far to wherever you will get the alignment done, you will have to do an approximate alignment with string etc before you drive there.

Start putting penetrating oil on the track rod ends now. They seize up. Both of my cars have had seized track rod ends - only discovered when trying to free them off for alignment.

There’s a garage near me that can do the alignment so don’t think I’ll worry about the string. I’ll do the b12 first and maybe following weekend do the lcas. Can spray up the rod ends too and leave it to work for a bit. Thanks for the heads up 🤙

Is it worth changing the upper rear shock mount? That’s the one thing I forgot to order. Could go powerflex (or similar). Does anyone know the thread size on the b12 rear shock, m10 or m12? Just compiling the last few bits before the install on Saturday 🤞

Might as well change the rear upper mounts while its apart as they do wear, get genuine BMW ones from Cotswolds on here part numbers below, 2 of each does both sides.

Guide support, lower part : 33506771738
Guide support, upper part : 33506771737


Thread size, which end as they are different top and bottom ? they are both M10 but different thread pitch, if you buy new top mounts you will get new top nut as its part of it, bottom nut should be ok to re-use but if you want new its part number 33506784003

The top thread, as powerflex do two kits, one for a m10 and one for a m12. I haven’t read anywhere about anyone using the powerflex kit though, so not sure if that’s for a reason! Maybe they’re too stiff? I might get a new nut for the sake of it, less chance for something to go wrong Image cheers!

I've used the powerflex ones on mine when I replaced the suspension with the B12 kit as part of the refresh. I can't say what difference they make individually or if they are even worth the extra over new standard parts as the whole lot was replaced in one go. I've used powerflex stuff on previous cars with good results so thought why not in this instance.

They were very well made and will probably last much longer than standard items in my opinion.

Got the kit on the car at the weekend, the front stayed the same height and the rear came down about 20mm. So no dramas there. Bit of a PITA job and had to make do with some tools I didn’t have but got there in the end. Haven’t given the car a nice run yet but feels good on the commute into work. Also done the camber pin mod whilst I had the new top mounts it was easy to press the pin out.
M3 LCA and rear subframe bushings to go this weekend hopefully!

I went with these too, seem well made
