I can't understand it either. its not something I'd have really sought out but once I read about it, seemed like a decent idea and $200 is a drop in the bucket for modding a car so figured it couldn't hurt. and now all I want to do is go drive around even more than usual! haha.
Some months ago, I wrote this in another thread, thinking about the Z1 Motor Mounts. Granted, I was thinking about them in the context of my old Maxima, which was a transverse-engine, FWD car. But I think the concepts still hold.
Pros:
- It's a handling mod, because body roll is reduced when the engine is more connected to the frame.
- It's a power mod, because energy previously wasted tossing the engine around is now being transmitted through the drive-train.
- It's a transmission mod, because shifts will be smoother with less movement.
- It's a driving mod, because throttle response will be significantly improved.
- It's an ego mod, because the added NVH turns your sedan into a racecar.
- It's an economical mod, because at $200, plus installation, the price is right.
- NVH that you can't turn off. However... you might actually like it.

i don't disagree 4 inches is crazy. but it's easier to cut material off than add it. unless you have a pen cap handy. haha.
but my thoughts are not only would it POSSIBLY look ok but it may be more fun/useful for spirited curvy drives because you can have both hands on the wheel with less time removed to shift. and I've always loved the look of old school Ferraris with the same shift style. I'm very prepared to hate it but $50 is a very cheap experiment so we shall see. Not at all defending my crazy, just saying if it doesn't work, i'll have no issues tossing it in the trash.
what does NVH mean?

It's a common automotive term that stands for "Noise, Vibration, Harshness".
The problem (?) as I see it with those extenders is the mid-section. About half a year ago, I wrote TWM asking them about a shorty extension. They said it was a good idea, and would forward the idea to other people in the company. Yesterday I re-opened that email thread and bumped the idea again. Don't have a lot of hope anything will come, but it's not like I'm in a hard-stop situation.
It's not really a 4" extension... think about it. If the extender is 4" long, but each end is overlapped by 1" threads, then what you have here is a 3" extension, which is no bueno, IMO. What I want is one of these extenders, but without that entire tapered mid-section. And even then, I'd still lop a little bit off the threaded ends.

Glad to hear you are enjoying the Z1 trans mount. Hopefully, you found a good fix for the height of the shifter. My shifter was ridiculously low too initially- to the point where I was dragging my knuckles on the shifter trim.
I experimented with some chrome spacers between the shift boot and the 8 ball shaped shift ****, but ended up getting a tear drop shaped shift **** and using a washer on top of the shift lever to raise the height. Now it's perfect for me.
I was trying to explain the NVH in a few threads when I got mine last year and with an aftermarket exhaust it is nice because the vibration almost enhances the exhaust by making it sound throatier. Like making the V6 sound more like a V8. I like the way it sounds at all rpms.

Well, John you've convinced me. I just placed an order for the TWM STS. I'm also upgrading the Transmission mount, but I didn't go with Z1. I'll share details on this other company's mount once I get it installed.

The only thing about the STS that bugs me is how low it sits once you get the entire console back together. I regained an extra 1/2" by sacrificing 1/2" of thread internal to my shift ****... and that made a really annoying situation almost irrelevant. Almost. I keep thinking there has to be a solution to get back to stock height. My original idea of buying a 10mm-to-10mm standoff in 1.25 pitch seemed a slam dunk... except that hardware doesn't exist. It just doesn't.
So I'm back to thinking about getting a coupling nut and manufacturing my own standoff. But I'm in no hurry, because things are good enough as is. It's going to be something I play with in the back of my head until I actually do something, or forget about it. If this is something you find a solution to, please share.

Chris from LatheWerks wrote me back, and he's amenable to the idea of creating a custom standoff. However, I think it's going to take a few more emails to get on the same page.
He always comes across as a really nice guy.
An alternative solution would be to have him cut a new ****, but lower the internals by 3/4". That would work, too, but be kind of expensive, particularly since I also have a winter ****. Unless I sold them online... IDK. I need to process these options.

There was a period where I was driving around with the entire center console removed, like in those pics up on top. And that was both before and after the STS was installed. The difference before/after was somewhat dramatic in the moment. Adding another inch of height isn't going to change it up that much, IMO.
Assuming 1/2" of thread contact is adequate, if I take a 30mm M10-1.25 coupling nut, and weld a threaded M10-1.25 post into the middle, cutting the extension from the nut by another 15mm, then the coupling nut would screw onto the shaft with 15mm of contact, and the **** would screw onto the extension with 15mm of contact... making the **** 30mm higher than otherwise.
So much math... LOL
Why only a 30mm coupling nut? Why not 45mm to max out thread contact on the shaft? Well, apparently the only commonly available M10-1.25 coupling nut is 30mm. Just like the availability problem with the stand-off idea, it's a piece of hardware that just can't be found unless you custom order 1000+ of them.

That's awesome, Liam. Really looking forward to your opinion.
