We run 96-99 M3 Front Control arms. These can be purchased used for cheap and new bushings can be pressed in easily. One of our Mid Atlantic drivers, Sean, will happily do so if you send him your arms for a core. These arms can also be bought new on Bimmerworld I believe.

Hi William:  Sean here in the #19 Spec3.  We use the 96+ M3 front control arms.  They can be slightly difficult to source but I have a couple spare sets and can press new E30 ball joints into the '96-'99 M3 control arms.  All the part numbers are:

M3 Control Arms
31122228462
31122228461

Lemforder E30 Ball Joints
31121126254
31121126253

Let me know if you'd like a set and we'll figure it out.  

Something else to consider is that your 1992 325i came with a non-vanos engine.  We all run the 93-95 single vanos 2.5 motor.  Not necessary for DE but eventually you'll need to swap the motor to be competitive.  Good news is that lots of people like those non-vanos motors because they handle turbos very well.  So you should be able to sell it easily.
