If you try to push the sleeves out you will ruin the bush as they're bonded in place. I would make solid spacers rather than use several washers, or just cut the ends off the old shock sleeves?
Thanks for the feedback, solid spacers are now on order.

I measured the original bush/spacer combo at 54mm, and the new at just 40mm, but the bolt when fully inserted is about 3mm out, so will be using a 10mm 12/20 spacer and a 2mm m12 washer on the outside. That should give 2mm more thread contact than before but roughly in same alignment, and most importantly, nice and secure.

Oh oh, not a good day...

So all was going well.
I painted up the old rear top mounts which were in perfectly good condition.DSC_2168.jpg

The induction elbow I'd order turned up. So removed the airbox and sized it up...

Bit of trimming...

Attach the K&N at the 70mm end...

On to the maf housing with the 80mm end...

Perfect... I't away from the engine, low down and i'll add the ducting later to take air from in front of the wheel well.
Anyway, I need to mock up some sort of mounting bracket, so for now. A bit of offcut is the perfect way to fit the wee 1.0 Micra Green Filter I found in the garage a few weeks back.
Yes, yes, it'll starve at high revs, but i doubt it'll be there long.

So, I'd already removed the rear calipers and cleaned them up, so quick coat of primer...
DSC_2189.jpg

A few coats of colour...
DSC_2191.jpg

And time to start bolting things on...

DSC_2196.jpg

Oh, this is going to be good...
DSC_2197.jpg

Oh oh.. show stopper!
The 325mm E46 330 Sport brakes fit the Z3 just fine, and the 17" 5 spokes (style 18) just fit over. Great I thought, and they look awesome!

BUT.....

The wheel weights don't clear the caliper!

I tried moving them inward a little, but still no good, so we're stuffed.

For now, i've popped the 1er's 18's back on and there's loads of clearance. You'd think about 0.5 inch... right?
Nope, nearly a full inch. The problem seems to be the design of the Style 18's just restricts the clearance space.

So what to do?

I have several options.
1) Sell on the 330 Setup & Revert to OEM Brakes, and get some matching disks and new pads. Cheap and get the keep the original look.
2) Sell on the 330 Setup & go for a E46/Z4 300mm setup. Hopefully break even, but time and effort wasted.
3) Sell the freshly refurbed 17's and buy another set of 1er 18's. They do look great, and I've never seen another Z3 on them before. What are a freshly refurbied set of 17's worth? I have brand new tyres still to be fitted, though could return them.
4) Had this idea... Remove the tyres, and move the weights to the inside? This that a done thing?
5) Fit a wheel spacer. The Wheel is tapered so the further out it sits, the more clearance it'll have. Will trial fit a 3mm spacer tomorrow and see if that might work..
6) Haven't thought of a sixth option.... any ideas?

You can get the wheels balanced on the inner or the outer edge i think. They set the machine up for the different placement would be worth asking but sure it can be done.:thumbsup:

I think you have to have a lip on the rim for that to work, which the Z3 rims don't have. Something like this....


Can't move the weights any further out without placing them on the visible face, which would look pretty horid.

Will nip outside here and take a few more photos...

You can set the machine and using stick on weight fit it on the inner edge or just behind the spokes.

You can balance behind the spokes.

Can be set to balance like so can you get it cleared with weight on inside edge?

I think you guys are vastly underestimating the clearance issue here. There is about 1.5mm between rim and caliper, there is about 1mm of clearance between caliper and spoke.

Unless the weights go over the edge on the visible part, i'm not sure how to make this combination work...

Looks a bit daft, or am I being too critical?

Does the gap improve when you fit the anti-rattle spring Aaron, the calliper isn't pulled completely back to the carrier without it fitted. It may not be quite as bad as it looks?

That really is mega tight im sure you can space the fronts on the stock set up but not sure even that would give you clearance :(

I don't think it's as bad as it looks Ant, without the spring on and not even had the calliper pumped out (which will pull it away from the wheel) it can't be anywhere near it's final operating position. I think Aaron needs to finish the brakes before making any decisions.:)

You're right. That would help things a little. I didn't want to fit the springs yet as the paint was still soft, but i'll get the rear's on (since I know they're staying) and then get the front left bled and fitted properly before giving up.

Lol one more time....
DSC_2213.JPG

Right, no time like the present....

In saying all this, my dad has now announced he'd quite like a set of 1er rims, but i'd love to keep the wheels original and retro.

As Jim would say, "And then the fight started" ;)=))=)) I think there'll be more room when you get the callipers pumped out too Aaron. Like the colour mate.

Ok, Tony, I owe you a pint, or rather the guy down the road trying to sell his 1er rims on ebay wants £600 off you, since I don't need to buy his wheels any more.

I carefully stuck the clips on and bingo, about 2mm of extra clearance and a rotating wheel with a very carefully positioned wheel weight.

Thanks Tony :thumbsup:

Tbh, I feel stupid now as it's sorta obvious now, but I guess the disappointment of my dad standing looking in amazement at the big brakes, closely followed by "err, those wheels don't rotate" kinda threw me off.

Right, just nipped in from the cold to spread the good news. Back to it. Taxed the car earlier today as an incentive to get it on it's feet. Who needs to sleep anyway?

Been there and done that mate, I'm just happy that you can keep the original wheels if that's what you're wanting. You are both going to enjoy that car regardless of what wheels it has.

Tony.

ps. I drink Foster's;)=))

Yeah, I'm chuffed they get to stay.

When we started out looking for a Z, we had the intention of finding something a bit unloved or in a less desirable spec, and making it better within a limited budget. There aren't a lot of OEM Z wheels, other than the style 18's, that we liked, so had even picked a set of aftermarket, along with some other bits that we would use on the project.
We never expected to get a car this good and I really value the rarity of it's original spec, with the paint, seat colour and background history so the wheels from the original build sheet need to stay.

Even all the stuff i'm taking off the car, I'm cleaning up and putting in storage. The radio (sorry @oldcarman), brakes and suspension and airbox, even the original mirror glass all getting kept incase we ever feel the need to restore to factory spec, but for now OEM+ is the vision, as it was for the M3 and Pug.

Actually, I've not actually shared any info on how we came to own this Z yet...

Anyway, about 5 or 6 weeks ago, an ad appeared on Gumtree, and I literally jumped in the car and went to see it. Having looked at a few other Z's, and knowing my way around these cars well enough, I knew as soon as I saw it, that it was the right car. But it was in a field, covered in filth.
How did it end up here?

The car had actually been sold for scrap to a local breaker. Yeah, scrap! :confused:
It's had one owner, only 58k miles and full dealer service history, and as we now know, was it almost perfect condition, except some wobbly seats and one rotten outer sill. The battery had died, so the owner got it toed to their local dealer who replaced the battery, fired it up and announced the ECU had blown. New ECU + Battery + Toe Charge was more than the owner was willing to pay, since that involved messing about with the EWS, keys, etc..., so told them to get rid.
They contacted the breaker, who only really valued the engine, gearbox and diff for scrap and had actually advertised those parts on ebay, gumtree and facebook back in December. I've even printed out copys of the scrap ad's for the history file. Fortunately, no one was looking any of those parts at the time, so the car sat waiting to be broken.

However, over christmas the breaker decided to take a look at it and found a fault in the alternator (or maybe someone came looking an alternator and he was going to sell this one before they realised it was over volting), so he swapped that plus the ews, ecu and some other bits off another m52b28 car he had lying in the field and bingo. Z running smooth. Apparently he was considering keeping it himself, but i think he's got enough vehicles about so just wanted to move it on.

Anyway, the punchline of this story is that he only wanted the scrap value of the engine, gearbox and diff for it. Ok, 50k running gear goes for good money, but still, the rest of the car was free, and I blagged a few other parts out of the yard whilst i was there, including these brakes and a purple tag steering rack for the M3.
The rest you may already know from the thread: I collected it, drove it straight to MOT, passed, home, cleaned, cleaned again, and now upgrading some parts, before servicing, some more cleaning and finally handing the keys over to my dad.

Been a fun project for me to work on, and have definitely become a Z fan just learning about them and seeing the enthusiasm from everyone I've spoken to. Far more than I see for the M3 or Pug

Can't wait to get it complete, take it for a drive and feel the difference from the day we got it. :woot:

What a great story Aaron. Those ads you've printed will look great in the service history, which by the sounds of it has all the right stamps already. I'm in a funny situation here. I want to see the car in all it's glory when finished, but I've enjoyed this thread so much I don't want it to end.
Your dad is going to love this car mate. Well done.
I really appreciate all the time and effort you have put in to keep us all informed of the progress you have made. For people like me, who don't have the skill to tackle these jobs, these threads give us an insight into a world we wouldn't normally see.
Thank you Aaron. Phil
