The power steering system uses a Z3 power steering pump with N62
Exhaust is not completely finished but is a true dual all the way back, into E92 M3 resonators and X pipe and then dumping just past the mid pipe. Eventually I am going to rebuild this exhaust, it sits a little too low right now and drags over speed bumps and it's way, way too loud like this.
Suspension consists of mostly all stock Z3 non-M components. I have aluminum E30 M3 control arms and Koni yellows with H&R's and an M strut bar assembly because the M strut bar is contoured in a way to provide better clearance where I needed it.
The E30 M3 control arms are a pretty significant weight savings of over 50%, a 6 lbs saving per arm in unsprung weight.
The Koni cut-a-strut's are for M application, but I used non-M strut bearings to maintain correct suspension geometry.
The rear has upgraded E46 M3 upper shock mounts.
Quite happy with the fitment. The springs are designed for the M engine and the total weight seems to be pretty close to the V8 swap because the ride height is about identical to my M's with this suspension.
Eventually I will get around to rebuilding these Fikse FM-10's. The rear has about 1" spacers and I plan on buying new barrels that are 1" deeper in the rear.
