Cheers, I really like it. The downside is that like carbon black, it shows every bloody mark up as soon as the sun hits it.

Another catch up post…

Last week it was time to sort the front discs and pads and to change the passenger side wheel bearing so the disc retaining screw could actually be used. I had previously noticed that the dust shield was held in place with zip ties, so with the bearing off it seems like a good time to replace that.

Passenger side disassembly started

The offending stripped disc retaining thread. I had tried running a tap through it before but it made no difference.

Cover removed to reveal the 46mm nut.

The nut came off surprisingly easily given the factory torque setting and the bulk of the bearing slid off by hand just leaving the inner race behind.

My bearing puller fitted on perfectly. Watching a few videos on line and making sure it had flat ends ensured it fitted perfectly and it soon had the race off.

The rearmost dust seal was really rusty and basically disintegrated leaving a small piece behind that basically needed breaking off.

The old retaining bolt for the dust shield took some removing, but it was eventually removed.

New bearing fully pressed home following a slight battle getting the rear dust seal fitted. Front cover all popped on, ready for the disc.

I had been expecting the bearing to be a horrible job, but it was actually quite easy. Having bought tools such as the bearing puller made it loads easier obviously.

ATE power discs were fitted with ATE ceramic pads. Passenger side nearly there.

Drivers side was next. The discs and pads were pretty much new but NAPA and they created loads of dust….i had intended to just change fge pads to ceramic ones but I’m a bit of brake snob and like ATE stuff.

After a brief drive to start the bedding in process, I think there is a bit more bite to the brakes than there was previously. I need to do the rears as well which will see a massive reduction in brake dust.

Callipers will be painted in due course too.

A week or so later, I took a doc another nice evening to tackle the rear brakes.

Discs were pretty new but a bit crusty, particularly the drivers side.

Old disc and pad came off easily enough. The hand brake shoes and springs were cleaned up as best I could with a toothbrush and brake cleaner. They’re BMW branded so most likely original.

I’ve had a crack at adjusting the handbrake, so hopefully that’ll be a bit better than it was too.

Next jobs are to have the A/C regassed. It’s working ok, but there’s no evidence of it ever being touched, so I figured I might as well.

It’s off to Spires on 5th June for a proper alignment and set up which will hopefully get it driving nicely.

Top job.. Nice work.
That corrosion looks like something from a WW2 shipwreck!
Mine are crusty, too, just surface rust but looks a state.

It looks works than it is; when I wire brushed it nothing flaked off. I guess that’s the joy of a seaside car.

I’ll clean it up and treat the underside of the car as best I can this summer. Amazingly all of the bolts that I’ve had to undo have come undone pretty easily.

I’ll get that bit out the way first. I went into the office on Tuesday and parked in the nearest multi storey car park which I’m usually super careful in because the ramps felt awkward in my 335i which had much better visibility. I had a moment where I wasn’t as careful as usual and heard a scraping as I turned left. I assumed that it was my rear wheel and I was very angry with myself all the way home.

I arrived home, checked the wheel and it was fine. I then spotted this…. :headbang: :headbang: :headbang:

Image

I’ll get a proper repair sorted in due course, but in the meantime I made it look much better with some effort with a clay bar, fine wet and dry and some touch up paint.

Image

The better news is that I’ve been working my way through a few other jobs which success.

Firstly, I plugged in the connector that I’d removed to fit my aux socket so phone calls now work properly in the car. My BlueMusic adapter arrived and was super easy to fit and my phone connected first time. The infotainment at least feels a bit more modern than it did.

I used my wife’s E91 to drop my new wheels off for paint but the new rear tyres hadn’t arrived in time. I managed to squeeze a pair of Asymmetric 6’s in the boot of the Zed.

Image

My spacers arrived today so I spent a few minutes chucking them on.

Rear, before.

All of my suspension parts have arrived now, so I’m hoping to start work tomorrow night and finish Saturday in time for an alignment on Monday.
Hi Sam
Quick question, which spacers did you go for and where from?

Catching up on a few bits with my Z4.

The alignment that I had done at a local place was a bit rubbish to be fair and although the car was driving better than it was there was definitely room for improvement. I booked the car in with Spires in Leamington Spa.

First up it was popped on ramps to check the state of bolts / bushes etc.

Once Matt was happy with everything, it was then time for the actual alignment.

The passenger rear wheel was toeing out so was probably a major contributing factor to the car feeling a bit squiffy, particularly in right hand corners. The rear camber has been dialled down a bit and overall it’s massively improved and is much more confidence inspiring to drive now.

Next up was sorting the interior trim.

My car came with the gloss back trim which I understand rare and quite desirable but mine was in really bad condition. It looks like it’s got too hot and cracked in various places. I also don’t like the gloss black trim because it’s not a practical finish in my opinion. It shows dust and finger prints to easily as well as minor marks.

My solution was to buy a set of brushed aluminium trim and wrapped in 3M carbon vinyl. The wrapping part was easy but getting the trim off was another matter, especially the centre console trim.

Getting the centre console trim off required an awful lot of the interior to be removed….

With the console out, I was able to gain access to the three million torx screws that hold the trim to the console.

Certainly is a PITA . Good to see the jobs getting ticked off and the carbon looks great :thumbsup:
