Moved from my other FS thread, as everything was getting a little muddled!
One conversion I never got around to doing before the zed left me, was the uprated anti-roll bars, which I have just retrieved from the garage who had assembled them. The ARBs are from an E46 M3. The front and rear ARBs were both second-hand, but have just been powder coated. This conversion has been done elsewhere before. Here is the spec sheet for the Z4 3.0i (this is the same for the 2.5i too, so far as I can tell):

and here is the one for the E46 M3:

All the parts are the same aside from the ARB and bushes. Brackets, etc. are all identical. The standard Z4 runs 24mm front ARBs, sport suspension runs 25mm - the E46 M3 runs an even beefier 26mm. Here is the assembled item, which the garage said should bolt on nice and easily. Comes with all new brackets, bolts, blue Powerflex polybushes - and a brand new (unopened) pair of Delphi (non-OEM, but quality) links (p/n 31356780847 on the diagram).
I'll sell this one complete for £45 plus postage. The Polybushes cost £30 on their own, let alone all of the other bits. It is very heavy - postage could be about £15, I'd guess - will firm it up for a buyer. Happy for someone to pickup...
The rear hasn't yet been assembled fully. It is a 21mm bar and needs special bushes to fit the Z4's brackets. I bought a set of Powerflex PFR5-504-21 bushes, but the garage said that it would be a tight fit - probably because of the powder coating. They could probably do with PFR5-504-21.5 bushes. Because of this, I'll sell this one for £30 plus postage. It's not quite as heavy - probably £10, but I'll firm up that price too...
Will post a pic in due course, but here are both disassembled:
Any interest, please PM me
