Steering rack OEM BMW or OEM Mazda
Untapped market - BMW E39 530i - can find decent examples 3k or less.
Reliable 3.0L inline 6, 5spd ZF gearbox, all aluminum suspension components, steering rack with a ton of angle stock, factory power steering cooler.
Pros: reliable, factory power steering cooler

BMW
You have to trim a good 2 inches out of your firewall depending on where your rack is mounted. I’ve found that all racks are not perfectly the same and some require more trimming. I used a bur bit and die grinder and got it done in a few minutes. I also made my own grommet plate from Abs plastic. The z3 rack is by far the best thing I’ve done to the e30.
Pros: best upgrade, improved handling
Cons: firewall trimming required

In terms of performance, bushings have already been covered, but I haven’t see a Z3 steering rack been mentioned yet. It basically makes the steering snappier and the car feels more go-kart-y.
Pros: steering snappier, go-kart-y feel

I have installed two Z3 racks, I love it... Bought both used on Ebay from CA from low mileage cars and look fantastic, wouldn't hesitate buying used from a salvage if you know the mileage.
Pros: love it, look fantastic

I put one in my car and didn't retrofit servotronic and I firmly believe that was the best steering i've ever felt in any car in my life.

Pros: highly recommended, improved handling

The G30 5 series had broken steering rack... all happened under warranty period too. They got it fixed for free but that's the most problematic new car my parents got.
Cons: broken, problematic
