Prospective G37 manual tranny buyer

My next mod (after I get the RJM pedal assembly installed) is for sure going to be the Z1 urethane trans mount. After installing my TWM short shifter, it's hard to get into certain gears while driving spiritedly. I know it's not alignment of the actual shifter because it's smooth as butter at a standstill. It's crazy how much movement you can see of the **** when you get on power / lift. The oem mount must be mush. Seems like the urethane doesn't add crazy amount of NVH like a solid mount would. We'll see if that cures my shifting issues or if I will need to do motor mounts too.

The poly trans mount might be the perfect compliment to a STS for these cars. If you get a STS, first (or part & parcel) upgrade the tranny mount to poly or aluminum. I'm thinking poly, because I'm not a masochist.
4DRZ?

Yes! LOL, but it feels like something just lined up here, and you nailed it.

Not sure how much louder it will be with Z1 or CZP motor mounts though. Anyone use these yet?

I totally believe that. You'll experience much the same with stiffer engine mount bushings.
Back in the 90's, there was a guy who would drive his red MR2 Turbo to work only on sunny days, and park it in the far corner of the Kodak R&D lot under a car cover. Seriously, a car cover, while at work.
I bet that was you.

On some cars, the shifter is mounted to the body and those cars will benefit from stiffer bushes as it reduces the flex between the shifter and body. (most front wheel drive comes to mind)
Some gearboxes you can be gentle with and some you can't.
The G37 gearbox seems to work best when not being gentle. It takes a bit more force to get it to do what you want.

Shifting on the 1-2 shift is smoother if you avoid short shifting. Shift at no less than 3000 rpm for a smoother shift. I also use the clutch spring mod. It helps.
After all of these years of owning my 6MT sedan I still cannot find a suitable replacement car. This car offers so much for the money. I love the look over some of the German sport sedans but fear the reliability over the long haul. My brother has a lot of little issues with his 335i M Sport but his car looks awesome with that appearance package.

Just this past summer my brother was looking for a used low mileage 2 seat convertible as a summer toy. He had his sights set on a used, out of warranty, BMW Z4. I actually talked him out of it (based on repair and maintenance costs) and instead found him a 2010 370Z with less than 7000 miles that was locally owned. He couldn't be happier with it!

The thing about the G37S 6MT that I find so appealing is the sleeper quality to it. G Sedans are a dime-a-dozen. But a proper 6MT Sedan, with worthy sportscar options direct from the factory, and a few simple bolt-on mods... you end up with a personal and unique experience.
In your world, I suppose the analogy is owning a 335is. Unique and worthy, yet still indistinguishable at a casual glance from the 3-series that litter office parks.
That said, the G you want will have LSD. The 335is... nope.

The only car I thought about other than a G was the N54 versions of the 335i or 535i. 535s are impossible to come by with a manual and the options I wanted, and the e90s that have the n54 are a bit fugly, especially out front. Also, out of warranty turbo BMWs that I would want to tune considerably seemed like a recipe for financial ruin. They are fast AF, though. My buddy just got a 1M Coupe, and with a few bolt-ons and tune, that thing SCREAMS.
The G is not as fast and takes a LOT more money to get even in the same ballpark (mods do VERY little when you're used to turbo cars). But they have good bones (BBK, LSD, hydraulic steering, 6MT, gorgeous exterior / interior *IMO, killer exhaust note *IMO), so I'm happy with the car. Even though it's nowhere near as fast as a turbo car could have been with the same $ in mods invested,its still a great bit of fun.

Since our shifter is mounted to the tranny and not the body, I can't see how shifter bushings will help your shifting issues.
On some cars, the shifter is mounted to the body and those cars will benefit from stiffer bushes as it reduces the flex between the shifter and body. (most front wheel drive comes to mind)
Some gearboxes you can be gentle with and some you can't.

It's hard to get it to go into gear at a certain location when the entire transmission shifts around and that location is constantly moving.
If I'm driving along at neutral throttle and hammer it, I can watch the **** move back 1/2 inch. Then when I let off, it moves forward an inch. And if I clutch in, it will move back a 1/2 inch to where it started at "rest".
With a short throw shifter that has the movement tightened up, it makes for some craptastic shifting.
