Z4M's use an offset FCAB similar to the '95 E36M3 and E30M3. What I am trying to figure out if the Z4M front wishbone will fit the hole in the above mentioned FCAB's.

Is it a perfect fit?
Is the wishbone too big?
Is the wishbone too small and requires a sleeve?

The ultimate goal is to find out if we (the Z4M's) can use an uprated FCAB from the older cars or are we stuck with the OEM FCAB.

I do know you 'can' use a centered FCAB but you have to realize that by doing this you change the suspension geometry (scrub and thrust first come to mind) and you WILL ABSOLUTELY have to have an alignment performed after this switch. I have calculated what the changes will be but I am not sure of some of the assumptions.

I am actually willing to go out and buy the different FCAB’s but I need some data first before I attempt this or waist my money.
