A bit of more work between either the rain coming horizontally through the garage / workshop doors or -5c frosts …
So today managed to reconcile how to tighten a 22m nut that fixes to the Ohlins internal damper strut that uses an Allen screw internal to the nut that requires holding to lock it..
I have 3 other versions of a 22mm locking device on order…issue is the nut is recessed in the damper tube..very little room for most socket types..
Meanwhile I spent ever hours with some 120 scotch pads roughing up the caliper paint and using more meths to clean the crap off..
Then sprayed them topsides with etch primer before hopefully tomorrow turning them upside down to spray the rest before the Phoenix gold and 2 pack lacquer..
Whilst they were drying refitted the first Ohlins damper carrying the 80nm/mm vs 60nm/mm spring..
Even routed the abs cable (on second attempt) the right way around the leg ..unlike the Ohlins service centre…naughty ..

Another day..
So finished spraying the primer on the other side of the calipers..
Then tackled the right hold Ohlin's strut..
Like so many things once you've climbed the learning curve life becomes so much easier.
Use the spreader tool on the bottom of the knuckle, sprayed loads of penetrating fluid in the gap..
Left it a while then the knuckle would slide down quite easily and managed to get the knuckle off the end of the strut with little difficulty.
So swapped another 80nm spring in place of a 60nm...looks like a bit of coilbound on the old spring..but no sag..
In the menatime got some lovely BMW Phoenix Gold spray paint on the the caliper top side..lovely colour..
Not sure whether the Brembo logos should be in white rather than blakc this time?
After that slippedthe RH strut in easy enough.
The folks before me have made a mess of the brake / ABS brackets so a bit of tidying up required.

New OEM rear lights fitted today.
Just looking at that last photo I took, those exhaust tips could do with a clean up. Does anyone have any recommended methods? I have Barkeepers Friend which I will try first, any other suggestions?
Solvol Autosol plus elbow grease..

Nice wheels
Took my car to BMW Stoke. They looked at it immediately and now booked in for warranty work in Jan with a hire car. Needs a new sump gasket. Noticed a little weep when I carried out the gearbox service. Needs the subframe Dropped which needs an engine support so not worth me doing it. 
Good job you have the warranty ..Took my car to BMW Stoke. They looked at it immediately and now booked in for warranty work in Jan with a hire car. Needs a new sump gasket.

Yes fab..sadly 5 mins after photo one of the rear calipers dropped on the floor..not so perfect finishProper job that. Black looks good!
A mixed day..carefully and successfully buttoned up the front end…thought I was on a roll…
On the backs I was trying to re-use the old M5 rear calipers and their cradles..all lovingly painted..
However..the now ‘proper’ brackets I’ve made for 345mm and 370mm rear BBKs are now machined and the odd combination of M5 cradle with 345mm ‘proper’ bracket fouls in various ways unless I use spacers..the whole idea of the ‘proper’ bracket was to remove the need for spacers to avoid clamping / flex / vibration issues..
So I’ll have to do it ‘properly’..that is use a F10 5 series cradle (the M5 caliper and the F10 5 series caliper are the same bar colour) with the ‘proper’ 370mm adapter bracket…of course I’ve run out of paint so there will be a delay…
If you followed all that you’re doing well..
