Our new to us 2015 F31 325D M Sport
Discussion
Up on my pals ramps this afternoon to assess the suspension and see what's what / what needs replacing...
All shocks/springs are original dated 2015, as are all the front arms
Rear arms have been replaced in 2020/2021 - all OEM BMW. Both front/rear ARBs need new bushes and the front drop links seem ok; but they'll all get replaced as they're not expensive
Fine tuning my parts list on Autodoc and will get that ordered in the next day or so...
Decided to go with Bilstein B4S shocks and Eibach pro-kit springs with new top mounts/fittings from BMW etc (rubber mounts, gaskets etc) as well...
Having been out in my pals 320D who's just had that done as his MOT failed with 2 leaking rear shocks; it drives superbly, handles well and is much better than my F31 as it is currently...
The drive out in an F30 330D on B16s showed me how superb they are; but not for a daily driver with a few long road trips planned... Just too firm unfortunately

All new suspension parts ordered (shocks/springs etc)
Gone for Bilstein B4Ss all round; new Sachs top mounts, Eibach pro kit springs etc via Autodoc, 41% off - can't complain at that! £700 all in, delivered![thumbup](/inc/images/thumbup.gif)
Will get the dust boots/rubber perches and gaskets etc from Cotswolds BMW & then it can all be built up on the bench and each corner swapped out smoothly etc![wink](/inc/images/wink.gif)
Going to give the arms/links/bushes another full once over on Tuesday whilst it's on my pals ramps for 30mins (so I can replace the front drop links that have failed) and see which other arms need replacing as I forgot to take a proper note the other week and have forgotten![rolleyes](/inc/images/rolleyes.gif)

Back on my pals ramps this morning
Going to replace all the front arms, drop links, track rod ends & tie rods etc... All original BMW from 2015!

Rear arms are a mix of original BMW 2015 and some dated 2020, so will replace the 2015 ones and the eccentric bolts/washers/nuts too as they're rusty as hell![eek](/inc/images/eek.gif)
![](https://i.postimg.cc/sDTHyHTS/replace2.jpg)
Just ordered them via Cotswolds BMW
And this happened on the way back home![biggrin](/inc/images/biggrin.gif)

It should be driving nicely after that refresh.
Those bolts are really crusty! The joys of road salt.
Yeah; they're bad (literally flaked as you looked at them) Those bolts are really crusty! The joys of road salt.

I'll get on them with WD40 for a good few sprays and then closer to the time, Wurth Rost Off Ice etc << Bloody good stuff and would highly recommend it!

100k refresh, sounds about on the money!
Will drive nicely after.. Mine was 120k and 20yrs and the difference was phenomenal.
Yup Will drive nicely after.. Mine was 120k and 20yrs and the difference was phenomenal.

Made a huge difference on my previous Jap import E39 touring and 540i Sport pal; makes it feel like a whole new car
![wink](/inc/images/wink.gif)
As it is, the F31 drives fine, no untoward clunks/rattles or wayward handling etc; but you can also feel its age and it's a bit loose at times...
All in it'll be worthwhile & well overdue refresh!

My 330d completed its 100,000th mile last month en route to Caffeine & Machine and scrubs up well for the mileage. I’ve often found the UK obsession with low mileage cars odd because if a car is well maintained, the mileage is often just a number.
Least you know its been used and looked after then!
My previous Japanese import E39 540i was prime example of why low miles isn't always better. 20 years old, 53k miles and every part of the suspension needed to be replaced, cooling system also and all fluids etc... Some of the rubber bits literally crumbled

Front & rear suspension arms, links and inner tie rods/track rod ends & their bellows ordered today via Autodoc with their 31% offer running

Quite a few bits, but it all needs doing really
Gone with a mix of Moog, Lemforder & TRW - some TRW & Lemforder parts were out of stock; but having used Moog a LOT over the years on my E39s and E65/F01 7'ers, I've never had any issues, so happy to stick with them![smile](/inc/images/smile.gif)

It's going to be like new when you're done.
I like those winter mats, they look good and much easier to clean than most.

I'm looking forward to seeing how it drives after all that lots replaced
![biggrin](/inc/images/biggrin.gif)
Yeah they're decent mats; got the interior mats 2nd hand but like new (still in their original packaging too as the seller had moved onto an X3); a quick spray with ACP and a wipe off and they're done... Cannot stand those rubber mats that are like a mesh and you can't clean them without removing them and rinsing them off etc
OEM BMW CF/alcantara handbrake fitted ![biggrin](/inc/images/biggrin.gif)
Looks well and feels good in the hand

First of many parts ordered arrived via Cotswolds BMW also; this is all the necessary rubber bits, gaskets and some bolts for the suspension overhaul. The rest of it is arriving via Autodoc and snail-mail![laugh](/inc/images/laugh.gif)
Some bulbs in there too for a change this weekend and a spare bulb kit etc

Headlight bulbs changed; gone with the Lunex 6000k ones for now. Faffy, but done. Wheel off job; fortunately the little service hatch is big enough to manoeuvre my fat hands ![biggrin](/inc/images/biggrin.gif)
Osram Xenarc D1S bulbs removed; passenger side had gone yellowish, so time to change them anyways...
Front indicator bulbs swapped out for the Osram Diadem chrome ones too; looks much better

And freshly washed too with a good coat of AGs' Rapid Ceramic spray to see how that fairs over the wetter/dirtier months:

Probably the last full wash I'll give it now until early next year when the weather improves; will stick with contactless washes for now
