We used E36 tie rods on my car. The e30 ones don't fit the rack and the Z4 ones don't fit the car as I understand it.

No unfortunately I did not get any progress pics and once installed it's hard to see (obscured by everything else in the engine compartment). You can see the part he shortened here though: http://www.realoem.com/bmw/showparts...82&hg=32&fg=30
I think he cut away 3/4 of the sliding adjustment area.

Yes; the sliding piece has some very interesting parts inside that we choose to omit- full race car
*********
There are 4 -5 ball bearings on each side held in place by a plastic retaining clip; the shaft is designed to slide telescopically on these ball bearings.
*********
We choose to weld it solid as there are voids and the BMW engineered design of the steering shaft is compromised when cut down drastically in length. Our team has a professional materials engineer on board as well; so we don't tread lightly on anything safety system related.
We had our machine shop weld steel rods into the ball bearing channel to fill the void and weld it all together. I did not feel that plastic retainers holding a bunch of balls are going to survive our race abuse; banging back and forth every single time you turn; I always turn in while braking as well so many more forces adding up.......caged car and body by Tc design......stiff and solid bushings/billet engine mounts.........basically NVH up the wazoo.
******
I did not take any pictures or post details on purpose as this is a critical safety piece and I cannot be responsible for another's safety due to modifications.
We use this in a wheel to wheel endurance race car and your life is in danger every time you strap into that car and roll on track.
I'm not suggesting anyone improperly modify a steering part and take it on the street.

The most ideal solution would be to contact tiny tim and order a custom new piece made from flaming river u joints.

I believe these questions have all already been answered in this thread.
If not the bmw factory data published is avail online.
For bmw's:
Newer chassis= higher rack ratio number and more total angle.
If you have the budget and ability to fit a z4 rack; I don't see why a older z3 unit would be an option.

So. Z3 rack vs Z4 rack
-BOTH are linear?
-Z3 less tuns to lock but Z4 has more travel?
Which is the faster rack? If you were to turn both racks one revolution, which would have traveled the farthest?
Well I found one on ebay for $150 so it looks like that will be the route Im going.= Heidi 1988 325 -> 335i. 7200rpm built M30

Does sliding e85 non M Z4 coupler look like that?
And one of these 2 grooves in the shaft filled with these ballbearings is sort of visible?Last edited by raudonis; 02-17-2014, 07:40 AM.My transaction feedback on r3vlimited :):Clickety click

There are about 5 ball bearings? I forgot ours has 0.

Thanks for the information on this. I picked up a Z4 manual rack and thought I would contribute a few measurements I took from it.
Travel: 144.6mm
L2L: 3.0 turns
Rack ratio: 48.2mm/revolution
Steering ratio: 14.5:1 (e36 uprights)
18.9mm shaft, 48 spline (could be one or two off here as it was a quick check and hard to keep count). Seems like it's probably 3/4"-48.Last edited by mike156; 02-21-2014, 11:35 PM.
