But doing so with spacers is a bodge.

BMW themselves used spacers on the front of the e92M3 GTS to clear the strut, if it's good enough for them...

No doubt because was cost-prohibitive to re-engineer the hub assembly for such a low-volume model. And you'd have to be very good indeed to detect the difference that 5mm spacers will bring on a RWD car.

Spacers were a factory option on some 996 Porsches.

A manufacturer-endorsed bodge is still a bodge.

Your observations are spot on, but, it’s on the assumption that BMW got the track widths correct in the first place. Given how ****ing awful the standard set up is, and that the Z4 was a parts bin special, I doubt it is right. Had no issues running 10mm spacers all round on 224s on road or track. Initially I followed Exdos’ recommendations and I can’t credit him enough for his education & knowledge on Z4 set up.

Apologies if my earlier post came across snarky. There are strong benefits and rarely downsides to increasing track width. But doing so with spacers is a bodge. It adds to the gap between the hub face and kingpin which brings its own problems.

Having said that, you'd have to be very sensitive to notice 10mm spacers on a RWD car. It's the folks stancing their FWDs with 25mm spacers who don't seem to realise or care about what they're doing to handling.

Nothing to apologise for!! And you are 100% spot on with the stance brigade
It’s been quite the journey getting my Z4M how I like it. It is perfect? No, far from it, but its *way* better than standard

I think I need everyone to come up to Scotland so I can experience all the options first hand

Still leaning towards Intrax or Nitron at the moment, have sent an email to Nitron and will see what comes back. I’ll also get in contact with Martin from Race Parts.

Argenta, even on the stock wheels? I think every thread I’ve read about the KW V3’s suggests you need spacers.
Do you have any pics of the fronts?

Thats my point, that person really got the ball of rumour going...
Yes! Stock wheels, no spacers. At least 8-10mm clearance to KWV3 which is pretty OEM I'd say.
What pics would u like?

[Zspy]

If you don’t have any pictures to hand then no problem. I was just wondering if you had any pics of the inside of the rim with the KW’s fitted.
