BMW's Shortened from above shift lever

The shift lever is the Z4-2.5 one. Number on the right is the ratio of the shift lever. Be interesting to see what the Z4-3.0 one looks like. Will post a pic of it when it comes in.

Very short below fulcrum point.
No advantage to gain short throws with the reduced height above f/p.

I drove a 2.5 Z4/5 speed, but I can only recall that the shifts were effortless...
Now I know why.

You're too fast, I already edited out my booboo.

It looks "crimped" too...

My booboo. It was initially posted as Z3-1.9. All my uploads move over on the hour.

Z4-3.0 Shift lever

Received the Z4-3.0 shift lever today. This one and the 2.5 one open up some interesting short shift possibilities.
One example: A M-Z3 shift lever in a Z3-1.9 results in interference on most cars. The Z4-3.0 shift lever should work fine. Like the M-Z3 one, this lever has to be bent to duplicate the stock neutral position.
The uniform crimp at the base of the shift levers, shown in the following pic, was done using the tool Richard Mix made for me.

Ron,

So how about the Z4 3.0 lever in a MZ3?

It would give you a 1.8% reduction in shifting throw and the same increase in shifting force. The shift knob would set 5/8 inch lower than stock which is a nicer height in my opinion.

Thanks. Sounds like a plan since you you aren't doing M levers any longer.

It "looks" like the Z4 3.0 lever would fit a Z3 2.8.
Would these swap?

Sure. 18% reduction in shifting throw versus 16.5% using the
M-Z3 shift lever.
Go with the Whalon knob or one of BMWs shorter knobs for more.

Which of the above would make a nice addition to a 1.9 with a Whalen knob. I don't know too much of the science behind the levers, all I know is that the Whalen made my shifts shorter and smoother which is great. Would any of the above shifters work well with my Whalen in making shifts even shorter w/o causing problems

Thanks

The Whalon shift knob results in the following reduction in shifting throw on the Z3's using the stock shift levers.
Z3-1.9, 2.5, 2.5i = 14.2%
Z3-2.8, 3.0 = 15%
Z3-M = 15.3%



The M-Z3 shift lever in a Z3-2.8, 3.0 along with the Whalon knob would give you a 29.2% reduction in shifting throw. Nice mod. No bending required.
The Z3-2.8, 3.0 shift lever in a Z3-1.9 along with the Whalon knob would give you 33.7% reduction in shifting throw. Nice mod.
The lever would have to be bent to duplicate the stock neutral position. The M-Z3 shift lever in a Z3-1.9 along with the Whalon knob would give you a 44.8% reduction in shifting throw. Too much. Not recommended. This lever also has interference problems with the
Z3-1.9. The Z4-3.0 lever which is within a couple % of the M-Z3 lever looks like it will clear, but we haven't tried it yet. This lever would have to be bent to duplicate the stock neutral position as well.

Terry,

I'm trying to talk Ron back into Stygar Short Shift production.
Pester him if you'd rather go that route.
Same goes for anybody else too.

I prefer my lighted M knob, so I have made my own (a couple actually).

How hard was it to make your own? Instructions?

I keep pestering Ron, but so far he hasn't come through.

He even has one left he has been keeping for a spare. I would be happy with that one.

It's yours if you want it. $150.00 for the lever with new suspension (nylon cup), two spacers (yellow washers), one circlip and some expendable.
Shipping included USA.

No.
I have brown Delrin AF (Teflon content) bushings in the shift lever of my cars. I have also done some by request.
The bushings I was refering to are the black Delrin front shifting arm bushings. The front of the shifting arm mounts to the tranny case via the guide pin (***** clip). Like the shift lever, they are press fit and hand reamed to size.

Ron,

Thanks. I will be in touch. I am out of the country right now.

I get back late 12/20.

E46 330 Performance

Will be interesting to see what the E46 330 performance shift lever looks like. The stock E46 330 shift lever has a ratio of 4.74:1. The E46 330 performance, claims a shorter shift. I assume that it will have a lower ratio similar to the M-Z3 shift lever. What's different here, is that the M-Z3 shift lever is not bent. The E46 330 performance shift lever is. Will post pics of it when it comes in. If it is what I think it is, it will open up a lot of short shifting possibilities using BMW stuff.

Ron as always is right on top of things..

Ron, Would you mine posting the part number for the two Z4 shifters? Thanks

I seem to remember you being partial to the 1 1/8" shortened shifter that you use to make. I had one in my previous Z3 Coupe and still brag on you. It was sweet! Thanks for all that you do for this forum..
