Sorry for going OT here but very interested to hear how you find the difference with the with the offset front control arm bushings.Hi Mate,
I live in Auckland and have just gone thru the bushing, rear subframe debacle.
On my 1999 2.8 Z3 mspec I have the following....
Black IE concentric bushings for the front control arms (offset to increase castor and further improve steering response)
IE rear shock mounts (replaceable red Nolathane inserts)
Powerflex purple rear trailing arm bushing
Powerflex purple rear axel carrier beam bushings
Powerflex pink differential mount bushing
Z3 Sport springs
Bilsten HD tourers replaced in the rear
Installed IE rear camber\castor kit to reduce tyre wear (I am going to get the bolts spot welded in place as they have a tendency to loosen).
Ingen carbon fiber air intake piping incl washable pod filter (ex E46 from TradeMe for $25, a slight modification and it fits like a glove)
I also run 235x17 all round now. Offset great in the front but I added 20mm spacers in the rear to move the wheel out to the edge of the body (like the front) and increase the width of the tyre track for increased handling).
Unfortunately the previous owner did look after the car, so a lot of work has been done just to make it safe.
I have had to replace the axle carrier beam and both rear trailing arms due to accident by previous owner.
The car is part of the family now and the combination of Nolathane bushings and castor\camber kit make the car much more stable and removes the twitchy rear steer....
I like the increased handling and stability and find that the additional noise and vibration is marginal.
I recently had to rebuild my rear brake calipers (seal kit) and replaced the rear brake hoses as they De-laminate internally with age.

I have powerflex purple throughout and BC Racing coilovers with adjustable camber upfront with -1 dialed in and that's made a nice difference with turn in. Just wondering how far you go before it becomes too responsive upfront.
