fr tho is it bad for the car? Or is this somehow better?
no its not bad for the car. these are meant to reduce movement in the drivtrain package that would result in weird torquing angles under heavy acceleration. Which can break other things.

Coming from a background in noise/vibration/shock mounts, I would say there is a chance it could be bad for the car. Mounts serve more than one purpose, one of which is to absorb drivetrain shock. Truly no offense to Twisted or any other vendor, but I doubt any of them has ever seen a transmissibility curve, let alone understand one. I wouldn't put these or any aftermarket tranny/engine mounts on my car.
No offense taken.

the main reason for the mounts being so soft from OEM is simply driver and passenger comfort. the drivetrain moving less under high torque loads is FAR less damaging than the Drivetrain torquing (moving) heavily then snapping back in place. These mounts are for increased performance via reducing drivetrain slop from engine making more power than the OEM mounts were designed for where they literally split and come apart. They are not for everyone. Replacing mounts is NOTHING new, and has been being done longer than most of us have been alive.

They are being worked on. Had to make some prototype changes from the last version.
I'd like to inquire about an expected release date for the motor mounts being prototyped? I've yearned for this part since the day I got the car and could feel how soft the stock motor mounts appear to be. The engine torque when shifting and on sudden power delivery/off power lifting is rediculous. I would like to buy these transmission mounts as well, but am waiting until the motor mounts are available as well so I can do them all at once.

You looking for someone to test them on the street and track? I'd like to humbly offer my services. I will even pay a premium for the prototype component. Please, take my money!

Vargas has billet inserts for the motor mounts. Check 'em out. Deletes the rubber bushing; BMW does the same for their race teams.

I found 'em just after I posted the above reply to see if anything new had hit the market since I last checked. I will check 'em out - seems like it may fit the bill, though I'd still prefer a solid chunk of metal or polyurethane (and yes I know what that comes along with). Does anyone by chance know if the motor mounts are specific to the design of the A90 Supra or if components advertised for the Z4 will work? May be more options available, just not specifically marketed for our cars.

Almost anything engine or drivetrain for the G29 Z4 will work with the Supra.

@Thraxbert , has your opinion about these changes now that you've lived with them for a while?
Nope, not really. I stand by my original position. I like the visceral feeling they give to the car, but I know there are others who want a smooth and quiet grand touring experience. It really just comes down to how tolerant you are of certain types of NVH. For example, rattles and squeaks drive me crazy. But consistent vibration from solid mounts, a diff, or trans... not a bother because the pitch is low.

I tried them a while back in an attempt to reduce wheel hop. I made it about 2 miles into my test drive before I had to turn around and jack the car back up to figure out what on Earth I screwed up. I couldn't find anything, so I went back out for a drive, 2 miles later I turned back around and pulled them back off.

I'm no stranger to NVH, both my WRX and STi have/had stiffer engine mounts, tranny mounts, rear diff bushings, outrigger bushings, shifter bushings, etc. On those there was a slight NVH increase and more gear whine, but it was fine. The tranny mounts on the Supra are on a completely different level. The entire fucking car SHAKES when you're accelerating. It feels like a race car. Like an actual, should never be allowed on the street, race car. I don't recommend it for any kind of street driving, it's insane.

That said, you can buy mine if you want. They were used for <10 miles and still look new.
