Z4 Coupe, Mini Project Thread...?

Another new Z4 Coupe owner has entered the building. I’ve always had a bit of a glad eye for these cars, I especially love the hard tops, the lines just work… I mean I’m preaching to the converted here but yaknow.

I spent most of last summer trying to grab the keys to my old man’s S2000, loving peering over the long bonnet and the whole driving experience, especially compared to my rather muted (in everything but colour) Solar Orange TTS, that said, not sure I could live with that budle of revs and excitement day in, day out. Anyway, I finally decided to take the plunge and cash outta the TTS, it’s been a great car but expensive depreciation wise, and with the lack of mileage I’m doing working from home I thought I’d take the plunge.

I picked this up from a guy in Leicester, I’ll admit I went with fairly low expectations due to the whopping 4 (or was it 5?) lines and subsequent limited detail in the advert. A quick nose round the car which looks pretty honest for near on 90k - few car park battle scars but nothing too untoward - a good thumb through the extensive history and test drive and I’d already arranged to go back with some money! It's currently on CSL reps and AP coilovers.

Driving home in the pouring rain wasn’t nearly as hairy as I’d be thinking it might be, and boy, aren’t these engines just brilliant. I love the gearbox, too, and a bonnet so long it’s like the automotive equivalent of a Chance Vought Corsair. Here's a quick shot of it as it stood on a trip to work to Thursday:

First job was to give the inside a bloody good scrub, get all the make-up and chocolate and other such detritus out the way, and scrub the bi-colour seats up. The interior on this car is really great, with bi colour seats and matching leather dash (not seen that before, despite looking at these on and off for a few years now!), no sat-nav (yay, keeps the clean lines of the dash) but unfortunately, no heated seats. Still, it’s all a compromise right!? Also put one of the Peugeot 6561N3 stubby aerials on too, very pleased with that and it looks a lot better than the silly long one it was wearing.

It’s done about 4000 miles since it’s last oil and filter change, although that was coming up 2 years ago so the second job was to give it an oil and filter change, new spark plugs and also change the rear shock top mounts. That was done today, although we lost a coil pack on cylinder 1 after swapping the plug. Luckily a friend was able to collect a new one in time for me to drive home. Also changed the D/S cupholder as it was broken, them’s expensive bits!

I’ve also managed to track down some of the earlier owners, both were really nice guys and verified the history of the car. It’s previously been a forum car, see here: https://z4-forum.com/forum/viewtopic.php?f=11&t=71807 A photo from above member of the car in France (something I may re-create, watch this space...!)

Anyway, I’ll stop rattling on. I’ve got a ZHP knob waiting to go on, and just ordered a fresh gaiter and handbrake trim from JF customs so I’ll wait and fit all that in one. It’s booked in for a full detail and dent removal at some point in the next couple of weeks, along with touching up some of the kerbing on the alloys. Other than that, I’ll see how it goes...!

Some photos from the drive home today... the long way, of course. First time I've had a good go in the dry :D

Thanks for reading if you've made it this far (or just looked at pictures)

Looks a nice example. Do you happen to know which csl reps they are and what size tyres it's running. I'm toying with the idea of getting some and keep changing my mind on which to get.
 
Welcome to E86 ownership Harry - but be careful, they can be addictive! :roll:

Yours looks to be sat pretty low on those coil-overs but then you can always adjust it, and for some reason CSLs/CSL Reps just look so right on E86s. :thumbsup:

IIRC the Bi-Colour leather was quite an expensive option, as was the carbon-leather dash so the latter seems to be more common in Ms - might be why the 1st owner didn't splash out on heated seats! Although my 2nd E86 didn't have them and I didn't find it a problem, but then it wasn't a daily driver.

But there is just something that feels so right sitting low down just in front of the rear wheels with that view down the bonnet and an N/A straight 6 that revs to 7,000rpm fitted under it. Definitely a very different experience to any TT I'm sure!

A ZHP is a definite improvement, but you might want to add refreshing the gearbox oil and removing the Clutch Delay Valve to your list of future plans. Being on here can impact on your wallet. :laugh:

And careful what you say about the aerial - the whippy v stubby debate has been running for years!

Anyway enjoy. :driving:
 
Welcome....lovely car that but then I would say that.
Mine...

Thanks - I'm not sure on the brands of the reps, I'll check the tyre sizes later. The rears are 255 wide off the top of my head, and they're fairly stretched.

Thanks! Yeah, I'll see how I get on but will probably raise it up just a notch or two, make it slightly more practical (it only just gets on the drive!). I'm not tooooo fusssed on the heated seats, nice to have but I'll survive without. The dash is actually bi-coloured leather, not carbon, and it has piano black trim around the gearstick, a nice looking combination.

The gearbox was done at around 75k looking through the history so it's not too high up my hitlist, although I'll probably do it next year along with the diff. One of the previous owners reckons the CDV might have been done, but I'm not too sure and wouldn't really know until we pull it out. I plan to do it at some point.

Haha, I don't want to start a bunfight on the aerial front!

Thanks! Yours looks really great too.

What are peoples thoughts on doing the water pumps as preventative maintenance? One of the few things I'm toying with the idea of doing, I can kinda justify the cost for peace of mind as the TT would've been due a cambelt so it's money I'd have spent on car maintenance anyway.

Took the car on it's first long-ish run today, 100 mile round trip to Duxford. Don't they just cruise so well, I was enjoying watching the estimated endurance go up while sat at 70... That's an unexpected bonus!

Thanks again.

I changed my water pump and thermostat on my roadster as preventative maintenance at 90k miles. So I’d do it, if you believe it’s still the original pump.

For info, cheapest I found the pump was £250 from here...

Hi,

Fronts are 225/35
Rears are 255/30 however when I come to replace them I may get something wider as these are quite stretched. It's also got 5mm rear spacers on the rear so I'll probably loose those if I have wider tryres.

Thanks, looking like I might be taking it to France in September so I'll probably do it before then!
 
Thanks for the info, they were the sizes I was looking at as they give the closest match to the standard sizes.
 
Bit of a boring update but sorted a little niggle today, the passenger side seatbelt guide was missing so put that right. Seemingly you can only buy the whole assembly so not the cheapest fix...

From this:

To this:

KsARSaP.jpg

Also fitted the ZHP, what a difference this makes. The new leather set from JF customs arrived but having pulled it all apart I've decided I'll get another set of frames for the handbrake assembly rather than butcher what's on the car. Still, nice to clean under the hanbrake section so not wasted effort (not that it's difficult)

I need to sort out the foglights, any recommendations to dry them out?

When I got my 2nd Coupe they were clear, but misted up over the first winter. Someone on here recommended drilling a few holes in the bottom of the clear plastic covers and that seemed to work pretty well. Failing that I think the only option is to remove them and split them which I imagine would be pretty fiddly. :(
 
Bit of an update today with a new set of wheels sort of.

Before I get into the wheels, potentially worth touching briefly on interior, particularly the re-trim pieces from JF customs, I went to look at how difficult it would be to fit and while looking at that decided I wasn't 100% happy with the quality of the new handbrake lever handle, particularly the cut-out around the release button. I decided to return them, which JF cutoms were excellent in processing to be fair. The rest of the leather looked really nice, the gearstick gaitor especially but I didn't want mismatching bits and with all the original leather trim pieces removed and cleaned properly it didn't look half as bad as before so all of the orignal bits went back in.

I decided to turn that £50 into some leather restorer for the drivers side seat bolster, a second hand set of front foglights (not for the seat bolster) and some 5% tint off eBay (also not for the seat bolster). The leather restorer has yet to arrive but the foglights have. Currently in a state of disassembly, I'm wishing they'd sealed the back of them as well as they fixed the lenses on, total pain in the arse to remove so far. My plan is to strip and restore the eBay pair and while I'm doing that, put some tint over the ones in the car as the condesation really, really annoys me. It's off for a full detail on Thursday so will faff about with the tint when it's back from that. I've also spotted a bit of rust on the boot lid itself (on the internal face) so that will be sorted while it's at the bodyshop.

I've been running with the fogs on in the day in a vain effort to clear them up, but no dice and they still look like this:

y2wq9Wz.jpg

So the wheels. I love the look of CSLs, don't get me wrong, but I wish they were 18", I'm also not a huge fan of the stretch on the rears and just prefer the look of a bit more sidewall... So I've been pondering what to do and on about my 8th trawl through the wheel thread on here a set of 216 reps caught my eye. I started researching the wheels and figured I could probably run the OEM BMW ones for the E90 3 Series. They do some less agressive ones for the 1 series too but they're even less common and command more money. Offsets are a bit more than standard at ET34/37 F/R but basically less agressive than running 15/20mm spacers which is fairly common (or so I've read to believe)... to be pedantic it's like running 13mm spacers front and rear on the standards.

tWrSec3.jpg

I manged to find a really nice set locally and after a bit of man maths hinged around my friend buying the CSL reps for his E46 M3, I decided to go for it. I tried them on today - they're on a smorgasbord of ancient run flats so was just a trial fitting to see what they look like on the car - and I'm quite pleased to say the least. I think the rears will take the 5mm spacer I have currently on the CSLs just to fill the arches a touch more, but I'll try this next time as it's back on the CSL's for now while I get the 216's refurbished - they look OK from a distance but while I have 2 sets of wheels and no tyres for the 18's it makes sense to take advantage of the savings in supplying them without tyres to the refinishing company. Huge thanks to my friend with the garage for putting up with me in and out and helping a hand (OK doing most of the work)!

We also raised the coilovers a couple of turns as I've found it just a bit too low for the local roads (and both mine and my friends drive!). I'm pleased with this and the combination of 18" rims actually, I think it suits the car. Once it's settled and on the new wheels I'll take it for an alignment.

Anyway, less words more pictures:

I think I'll have them done in Hyper Silver or as close as the refinishers can get it, minus the BMW Motorsport graphics this time. I'm just not sold on it... Also have new centre caps on the way, too! Be interested to hear peoples thoughts on the wheels.

So it's now sat back in the garage on the CSLs, still have a list of jobs to to do including;

  • Waterpump, I have a new one sat waiting to go in as preventative.
  • Front headlight level sensor link arm is snapped so this needs replacing.
  • Even after changing the rear top mounts there is some noise over bad roads so need to look into this more, suspecting the droplinks.
  • Foglights
  • New tyres for the 216's, looking at having Eagle F1 Assymetrics all round
  • There is some driveline clunk noticeable especially when reversing and sometimes between 1st and 2nd, done some research and it seems this either falls between feature not bug and needing to pack out the diff drive flange with grease?
  • New exhaust backbox from the Zed Shed mid next month

I'm sure I'll find more to go at but really enjoying the car so far!

Thanks for reading.
 
Good to read you are pleased with the ZHP - it's a definite improvement! But the fog-lights seem to be a recurring problem so good luck with yours. :thumbsup: Thankfully my MC doesn't have them. :D

My MC came with CSL Reps fitted and though like you I think they look great I would also have preferred 18" wheels and a bit more sidewall.

And I've got to say those 216s look fantastic! You shouldn't have a problem with rubbing. I fitted some E89 Style 295 wheels to my 2nd Coupe and the fronts were ET29 but didn't rub. The rears were ET40 but there was definitely room for another 3mm!

It's great getting a car exactly how you want it. :thumbsup:

Thanks! Yep, really impressed by the ZHP, got to say was a bit nervous spending £60 on one but certainly worth it IMO. Only now I'm also tempted by one of the Storm Motorwerks ones, maybe something to try down the line. Yeah I appreciate the fogs are just a common thing, I might drill some holes in the set I refinish to try and cure it, although not sure how the paint I put on them will last like that.

Regards the CSL's, yes... I just can't help think the 19's look just a smidge oversize on the non-m cars in my eyes, I do love the design of the wheels though, they're stunning. The picture I keep coming back to is the last one in my first post, the rear wheel draws too much attention... Each to their own though, some people on here must think I'm mental!

That's good to hear your experiences the front offset, I think I'll certainly try the 5mm spacer on the rear. Was just aware that the stretch on the tyres on the CSLs potentially gives a bit of room for clearance, but having fitted them I reckon it'll be fine, especially if people regularly run 20mm spacers as standard. Ran out of time last night to take them on/off again.

One last photo as I realised I didn't post a more side-on shot showing the 216s:

Have to agree with you on the 19" CSL wheels looking a bit big on these cars. Some 19" wheels don't look as bad by design.

I'd be looking at 18" wheels also

Yes, I was tempted to just buy a set of 18" CSL reps but thought I'd try something a bit different, kinda wishing the 224's in the classifieds had popped up a few days earlier. Tempted to buy those too :lol:

Yep, common sense also likes the cheaper 18" tyres!
 
You can get fog light blanking plates genuine BMW parts about £50 for the pair and have them colour coded?

That's my plan B (or is it C?)... But yeah if it looks unsatisfactory with holes and the refurbed ones go bad then they'll be blanked off.
