Hello,

Does anyone have the correct numbers of all the polybushes?
Is there a full package kit?

Mine is a 2.8 pre-facelift (if that makes any difference).

Thanks, Koen
 
The Powerflex website is set up really well for part numbers. http://www.powerflex.co.uk/road-series/products/Z3+(1994+-+2002)-603/1.html

Here is the breakdown of bushes required for the Z3. They have prices, but found eBay was generally better priced than direct

Then you get this PDF file which shows you all their part numbers. I then went to eBay and searched for them.

Was thinking about going for their black-version....as my car is only for trackdays.
Anyone any experience with this black-version?

I don't see any "kits" on their site.
Although I have seen them (front packages or packages for complete rear suspension) for different types of BMW's.
Does that mean that they don't do kits/packages for the Zed?

Regards, Koen
 
What about the "30" rear shock top mount.
I've seen multiple aftermarket stuff as this mounting seems to be "not strong enough".
 
It would seem sensible to switch out the top shock mounts if you are changing everything else. I do know others have switched to the Rogue Engineering shock top mounts as an upgrade.

Exactly my question:
What would be best? any of these "aftermarket top mounts" (like Rogue) or the powerflex top mount (which also looks reinforced - looking at the picture).

If you are only using for racing, I would consider solid bushing, or hardest material you can find, takes the what if element away of a rubber bush failing.

These guys do Aluminium or Derlin for race:

I have seen similar alu-bushings, but I don't know.
Wouldn't that do just too much?
There are still vibrations on a car's suspension. If it can't vibrate a little, it will bend or crack sooner or later.......don't want that to happen either.
 
I suppose it comes down to racing metrics snd costs, if you want to maintsin geometry during the full race you would go hard bushing, and hope for the best, F1 teams do this and the BTCC teams,mand I exoerd many if the top rally teams also, on the other hand if your doing it for fun and don't want to be changing parts continuously then softer bushing is better but at the expense of competitive edge.
