Hi all, just joined forum and wanted to ask some advice. I have read a lot online about the benefits of fitting an anti roll bar from a E46 M3 to my E85 2.5

also I recently bought my Z4 in Ireland and the owner explained that the drivers headlight has a beam deflector sticker fitted to pass the annual mot as the headlight is from a left hand drive mode. Looking for a driver headlight with orange strip indicator or a set if anyone has any

Cheers
 
ARBs are best upgraded front and rear at the same time. If you stiffen the front without the rear it could become more prone to understeer. I think the e46 M3 fits but not on the rear. H&R do uprated bars which is what I have front and back plus they are adjustable.
 
Steve is right that they should usually be replaced as a pair, unless you are trying to alter the handling characteristics.

I fitted a stiffer Eibach rear only E46 M3 bar with polybushes to my Z4M Roadster (to promote oversteer) a couple of months back and it fitted straight on, well, after I'd replaced the droplink that I snapped trying to remove the standard one! Truthfully there is little handling difference on track, but the M bar is pretty chunky anyway.

On realoem the standard E46 M3 rear arb is the same part number as the Z4M Roadster, so just check it will fit a non M Z4. :)

The M rear ARB will not fit a non M car.

I put the M front on mine. And it made a big difference I didn't change the rear. But i did fit a LSD so i am sure that helped the feeling of balance.
